Lin Qiangsheng used to think that the Japanese made the car body so thin, mainly to play a role in cushioning and protection when hitting pedestrians, ensure the safety of pedestrians, and reflect the spirit of humanistic care. Please search to see the most complete! of novels

But now it seems that the Japanese are doing this entirely because they have made the cushioning and energy absorption technology so advanced that there is no need for a hard car body, and the protection of pedestrians is just an additional effect of this technology. When the car is fast, it hits it, and no matter how soft the car shell is, it is useless, and the pedestrian still finishes playing.

In addition, he also learned from Nobuhiko Kawamoto that the design of the buffer energy-absorbing structure of various automobile manufacturers in the world is good or bad due to the problem of computing power, and the effect of the energy-absorbing buffer is also high and low.

Japanese automakers have invested a lot in this technology, one is because Japan has many small people and limited resources, and the other may be the ultimate spirit of the Japanese, this technology is extremely suitable for the national character of the Japanese.

Honda even refers to the buffer structure of the front and rear parts of the car as a buffer energy-absorbing structural part, and the buffer zone does not perfectly interpret this definition.

The buffer energy-absorbing structure is not contradictory to the rigid structure of the whole car body, but is combined, and the energy-absorbing structure is located at the front and rear ends of the car body, which is relatively soft. The central crew compartment frame structure will not have an energy-absorbing effect, but will still be made as hard as possible.

These two parts are usually made separately from different materials, with the former mostly made of composite materials, while the frame in the middle is protected with super-strength alloy steel. They are combined to play different structural roles.

The ideal overall body structure should have both an efficient impact buffer energy absorption area at the front and rear ends, and a strong enough occupant protection cabin. In the event of a collision with a low velocity, the energy absorption zone absorbs and dissolves the impact force, so that the impact force is transmitted to the occupants as little as possible.

Once the collision velocity is too high and the energy-absorbing area collapses, the impact force is still not absorbed, and the remaining passenger compartment will no longer try to absorb energy, but will rely on a solid frame to resist the hardness to ensure that the occupants have as much living space as possible. No crush injury. Because in most car accidents, the occupants are not killed, but squeezed to death!

Well, it's miserable to think about, except of course for cars that fall apart when they hit it!

The "soft" and "hard" components of the car body are blended together, and the buffer zone not only folds itself, but also conducts a part of the energy to the rigid cockpit structure during the folding process. Let the entire body share the impact force.

This is an extremely complex system engineering, and the Chinese automobile industry in the 80s has not yet reached this level of design!

Lin Qiangsheng almost immediately thought of learning Honda's technology. Thinking of Pixar, which he had just acquired in California, Honda did not show him their computing design capabilities, but he felt that the Japanese must have a strong computer design center.

Pixar's design capabilities are also very advanced, and its parent company, Industrial Light & Magic, claims that its computer technology is second only to the United States, of course, the outside world also thinks so.

Lin Qiangsheng can use Pixar's advanced computer technology to design a buffer energy-absorbing structure based on mechanical principles, or extend it to develop his own 3D car design software!

He found this to be a very promising and meaningful thing. Applying Pixar's computer technology to the design of the automobile industry can make a big step forward in the level of China's automobile design!

Nobuhiko Kawamoto continued: "In fact, there is a limit to the effectiveness of the energy absorption zone. With the current energy-absorbing structure technology, in a collision within /h, it is still necessary to meet the conditions of the real room, including the impact object, angle, etc., so as to basically prevent the occupants from being fatally injured. Of course, collisions in the real environment are much more complicated than in the real room. No two accidents are exactly the same, so /h is just a reference scale, and by no means all accidents below this speed will be fine.

Beyond /h, e.g. a collision occurs in /h. Obviously, the impact energy at this speed has greatly exceeded the resolution capacity of the existing buffer energy absorption technology, and the casualty of the occupants cannot be guaranteed. This is not a requirement for manufacturers to meet the crash tests of various countries. It is no longer to improve the protection ability, but to use the existing technology to do it at all. Neither Germany nor the United States can do this, including other Japanese car manufacturers, but at present, Honda is the best in the industry! ”

I saw the reserved expression on Soichiro Honda's face, as well as the arrogance on the faces of Kawashima Preferences, Kume Isshi and others.

Lin Qiangsheng reacted, nodded approvingly and said, "It's really amazing technology!" Mr. Honda. This buffer energy absorption technology is very, very remarkable, and important. It can protect the safety of occupants to the greatest extent, and I found that even the safety of pedestrians is also involved, this technology is indeed a good technology, imagine how much traffic accident mortality can be reduced every year, it is indeed worth promoting! ”

Soichiro Honda and others nodded yes, and also agreed with Lin Qiangsheng's words.

Lin Qiangsheng said: "China's roads are complex, most of them are of poor quality, and so far there is no highway open, which has caused a lot of trouble for drivers and pedestrians. ”

Soichiro Honda nodded after listening to the translator's words, and Lin Qiangsheng continued: "Mr. Honda, seniors, Honda has a very advanced buffer energy absorption technology, and China is also in great need now, please Honda Company to grant this technology to my Dongxing Company!" ”

"Huh?" Soichiro Honda was surprised, and Kawashima and Kume Shishi also looked at him with wide eyes in shock.

"Please, please teach us this technology, China's traffic situation can't be improved for a while, but we can still do something!" Lin Qiangsheng said sincerely, bowing twice in a row.

Hiroshi Honda touched his head, and he found that Lin Qiangsheng was so thick-skinned. Come on, your assets are richer than our Honda!

Soichiro Honda hurriedly said: "Hurry up, Lin Jun doesn't have to be so polite, this, we can teach your company's designers." ”

Kawashima likes to smile, and Kume is Shino looks up, as if there is a very novel business on the roof of the shed!

Lin Qiangsheng secretly said in his heart, nonsense, can you teach it, if our designers can come out of the cottage after reading it, then what technology is transferred, we must understand the details of the buffer energy absorption technology, and even why a support rod and a cushion are there. This process technology is what China lacks the most!

Soichiro Honda did not agree or refuse, and Lin Qiangsheng was not pressed too urgently, and he visited Honda's engine research institute.

Honda's engines are world-famous and have a very illustrious history. Honda originally started as a motorcycle, and the most critical thing about motorcycles is the engine, so Honda can be said to have focused on engines for decades. And it is also the only car manufacturer among the five major Japanese manufacturers that has participated in the F1 competition, which is the very famous World Formula One Championship. It is the most expensive, fastest, and highest-tech sport in the world, and it has the highest commercial value. The most glamorous and attractive sporting event. Because of its wide range of influence and high popularity, it is known as the "three major sports in the world" with the World Cup football tournament and the Olympic Games.

The sport is not well-known in China, and Chinese don't seem to be keen on speed racing, even if domestically organized events are always a niche sport. But in Japan, the event has a lot of fans.

Honda is the largest engine manufacturer in the world. Its history in F1 is divided into two phases: 1964~1968 and 1983~1992, during which Honda won a total of 71 Grand Prix.

In the period of providing engines for the McLaren team, 1983~1992, Honda won 5 consecutive F1 Drivers' Championships and 6 Constructors' Championships.

In 1983, Honda returned to F1 with a 1.5-liter V6 turbocharged RA167E engine that created a myth of 600 horsepower, beating Ferrari, Ford and Porsche. In 86, a new myth of 900 horsepower was created, and in 87, the maximum power reached 1050 horsepower.

Honda has taken advantage of turbocharging to the fullest. Until now, no manufacturer has been able to create such a large horsepower on a small displacement platform.

Of course, if it is said that the high-horsepower super-strong machine that needs to be overhauled after a race is not comparable to civilian functions, who will not lose life, but there is no doubt that the technology of no manufacturer of the same era can compete with Honda.

Honda, on the other hand, is at the forefront of many manufacturers in civilian engines, Honda's high-performance cars. The high-compression ratio engine without turbo is equally powerful!

The Honda Civic's B16B red-head engine, 1.6L naturally aspirated, actually reached 190 horsepower, which is simply terrifying.

Since the 80s, there has been a trend of high-performance cars in Japan, and at this time, various Japanese manufacturers have been chasing speed and passion more purely. It is under this special historical background and persistent car-making concept that a series of high-performance classic models were born, and behind each high-performance car there is a restless "heart".

They are Mitsubishi 4G63. Typical representative of the red-headed machine, 2.0-liter 16-valve turbocharged; Honda's K20A, double overhead camshaft and variable valve timing and lift electronic control system; Subaru EJ257, variable valve timing system. In addition, the Cummins 2.8 diesel version of the 170 horsepower red-headed machine is also a great product!

Lin Qiangsheng has coveted Honda's engine technology for a long time, because Dongxing's engine factory can indeed reach this height (naturally aspirated engine), as long as you master Honda's know-how!

Take the RA167E turbocharged engine distance, it can reach 1050 hp after supercharging, and the V6 engine with a mere 1.5L displacement can do it, the power density is quite high, and the advantages of turbocharging are vividly exerted, leaving the opponents of naturally aspirated engines behind.

The stroke of this engine is only 50., and the piston stroke on a typical car is considered normal above because it is necessary to maintain a certain torque, especially at low revs. Such a short range shows that the number of times the work is done at the same time, and the power is naturally improved, coupled with Honda's ultra-high pressure turbocharger, the normal atmospheric pressure is, so the non-supercharged engine can inhale less than or equal to air at most, and the boost pressure means that the suction volume of the cylinder is 4 times more than that of the atmospheric engine!

The engineers of the F1 teams are not fools, how can they not understand such a superficial truth, what is difficult to achieve is only the strength and assembly accuracy of the cylinder block, pistons, and connecting rods.

Therefore, Honda's excellence is not in its engine scientific research level, but in the piston quality with less than the manufacturing technical error that has been exercised in countless rigorous races, the connecting rod that can withstand 1275 times the gravitational acceleration, the crankshaft that has undergone high-speed treatment, the all-magnesium aluminum alloy cylinder block, and the assembly technology of extremely precision machining! )
