Lu Wenjun said with a smile: "Xiao Yang, then you quickly tell me what functional modules this software has." Pen, fun, pavilion www. biquge。 info”

Yang Weining nodded and said with a smile: "Next, what I want to introduce to you is the curved design function module. We are often familiar with surface problems, and we often encounter a large number of freeform surface problems in engineering, but after looking at the surface generation module I designed, I believe you will soon find that surface design will become so simple and efficient. ”

Yang Weining opened the surface design function module of AUTOCAD, created a simple freeform surface on the screen, and then clicked the edit bar.

Soon, everyone saw how Yang Weining used editing functions such as stretching, bending, and twisting to perform nonlinear modification on the freeform surface he had built.

Looking at the curved surface on the screen and changing its appearance casually according to Yang Weining's ideas, there was a burst of exclamation at the scene.

If the 2D drawing function just now opened a window to another world for the engineers of the 611 Institute, allowing them to have an intuitive understanding of computer-aided design, then this surface design function completely made everyone realize the power of this software.

It is important to know that in engineering, aeronautical engineers often encounter a large number of freeform problems.

At this time, they generally use multi-section views and characteristic latitudes to approximate the freeform surface designed.

However, the three-view method is incomplete, and it often happens that after the design is completed, the sample produced is very different from what the designer imagined, or even completely different.

The designer cannot guarantee whether the surface shape of his design can meet the requirements, so he also needs to make a clay model according to the scale as the basis for design review or scheme comparison, which is slow and cumbersome, and also greatly delays the development time of the product.

If designers can quickly and easily build and modify surface geometry, many projects can dramatically reduce design time.

Thinking of the time benefit, the onlookers couldn't help but have their eyes lit up.

IN ANY CASE, WHEN THE TIME COMES, YOU MUST APPLY FOR A COMPUTER AND AUTOCAD SOFTWARE FROM THE LEADER, AND MANY PEOPLE HAVE SECRETLY MADE UP THEIR MINDS.

Compared with those ordinary engineers with low political sensitivity, Lu Wenjun and Li Weikang, the two first- and second-in-command of the 611 Institute, think more.

The application scope of this software is not only limited to the aviation industry, but also in aerospace, ships, automobiles, energy, chemicals, general machinery, electrical equipment and other fields involving the manufacturing industry, has a wide range of application prospects, once it is popularized throughout the country, almost the entire Chinese industrial system has an important role in promoting.

It's impossible to imagine how much of a benefit it will be.

So as the developer of this software, Yang Weining is probably not just about getting national attention.

This kid really put a big satellite, and he must find a way to tie this kid to the chariot of the 611 Institute.

Lu Wenjun and Li Weikang saw the thoughts in each other's eyes at the same time.

Yang Weining naturally didn't think so much, and next, he showed everyone the assembly design module, drawing-space (2D/3D) integration module, aviation sheet metal module, electrical equipment and bracket modeling module, cable routing path module, wire harness installation module, electrical generation module and finite element generator module.

The Assembly Design module enables designers to build and manage mechanical assemblies based on 3D parts.

Assemblies can be made up of parts from multiple active or passive models, and the contact between the parts automatically defines the connection, making it easy for engineers to perform early analysis of kinematic products. Auxiliary part definition based on previously defined parts and automatic placement based on the contact between them accelerates the design of assemblies and allows subsequent applications to use this model for further design, analysis, manufacturing, and more.

The Drawing-Spatial (2D-3D) Integration Module fully integrates 2D and 3D environments.

The product enables designers and draftsmen to generate projection and planar cutaways from 3D geometry when creating 2D drawings. By controlling the 2D-to-3D correlation between models, the system can automatically generate patterns and cut planes from 3D data.

The Aerospace Sheet Metal Design module enables design and manufacturing engineers to define, manage and analyze entity-based aerospace sheet metal parts, and because Yang Weining uses process and parametric attributes, designers can add material properties to the geometric elements of sheet metal parts to describe them, so that designers can obtain design intent and provide necessary information for subsequent applications.

The Electrical Equipment and Bracket Modeling module provides designers with the tools to build a library of electrical standard parts. THE LIBRARIES BUILT WITH THIS PRODUCT CAN BE USED FOR AUTOCAD ELECTRICAL BUNDLE MOUNT PRODUCTS.

THE CABLE ROUTING PATH MODULE, WHICH USES THE SYSTEM PATH DEFINITION PRODUCT, ALLOWS USERS TO DEFINE A 3D NETWORK FOR ELEMENTS SUCH AS PIPES OR WIRE HARNESSES IN AUTOCAD DIGITAL MOCKUPS. The system automatically finds the best network path and automatically checks the connectivity of each node, taking into account the path in relation to the supporting constraints. User-defined rules can also be checked to ensure compliance with technical requirements.

The wire harness mounting module allows users to easily design and lay 3D wire harnesses in large or complex assemblies. Several features of the product automate the design, connection, modification, and analysis of laid wire harnesses. When optimally used with equipment built with electrical equipment and bracket modeling products, wire harness mounting allows the user to handle the parameters and constraints of the wire harness while the system manages the geometry.

Electrical Generated Templates, which use a 3D design built with a wire harness mounting product or a library of electrical and support parts created with an electrical device and bracket modeled product, calculates and analyzes the 2D template layout of the wiring harness.

Finite element model generator with automatic meshing function for easy generation of finite element models. The FEM Model Builder has an open architecture and can interface with other commercial or proprietary solvers. THE PRODUCT IS TIGHTLY INTEGRATED WITH AUTOCAD AND FACILITATES THE MODELING AND ANALYSIS OF THE ENTIRE FINITE ELEMENT MODEL IN A CAD/CAM/CAE SYSTEM.

These functions developed by Yang Weining are all extremely mature functions and technologies applied by CAD software in the aviation industry in later generations, but in this era, there are many unheard of concepts.

Even Professor Kuang Shilin of Huaqing University, who has been tracking the development of CAD technology in recent years, was dumbfounded, not to mention the engineer Rong Fei, who came into contact with CAD technology for the first time.

For them, these functions displayed by Yang Weining are like the Zenith technology depicted in science fiction novels, vividly displayed in front of everyone's eyes.

The expressions on everyone's faces also changed from casual at first, to some surprise, from surprise to sluggishness, from sluggishness to shock, and then from shock to disbelief.

In the end, everyone looked at Yang Weining's eyes, as if they were looking at a living monster.

Where the hell did this guy come from?

You must know that these functions introduced by Yang Weining later are all functional modules specially developed for the aviation industry in later generations, involving pneumatics, hydraulics, electrical, flight control, avionics, engines, overall layout, etc., which are very targeted.

The question is how old Yang Weining is, no matter how superb his programming skills are, if he does not have a certain level of understanding of the various professional classifications of the aviation industry, it is impossible to develop such a powerful professional module.

Not to mention, these modules involve all aspects of the aviation industry, and even Lu Wenjun, an old revolutionary who has been immersed in the aviation industry for decades, does not dare to say that his understanding of other professions can be so deep.

Especially the final finite element model generator, even if many people watched Yang Weining's demonstration, they felt like they were listening to a book from heaven, as for Chen Liangwei, Liu Yue, Jing Dongyang, who could keep up with Yang Weining's ideas, the expressions on their faces became extremely serious.
