Automotive vehicle system and parts system solutions

1 Overview

The automobile industry is one of the most important industries in the world and one of the most competitive industries. In the modern car design process CAE analysis plays a very big role, the fierce competition in the automotive market development cycle and quality of the car made a high demand, CAE role is that it can drive lean design and rapid car development process , Can save a lot of development costs, shorten the development cycle.

CAE technology applications for the automotive business has brought great returns. Statistics show that the application of CAE technology, the new car development costs from the development costs of 80% to 90% down to 8% to 12%. For example, the Ford Motor Company in 2000 after the application of CAE, the late development rate of 50% reduction, prototype cars and test costs by 50%, investment yield increased by 50%. Toyota developed a new Corolla Passenger Car using CAE technology to reduce development time to 18 months. Mazda relies on CAE and the test to shorten the product test and the completion time of the prototype, the completion of its product prototype from 3.5 months to 1.5 months, the test cycle from 4.5 months to 2.5 months.

If CAD is to help engineers create richer, more beautiful, more practical geometric entity design, then CAE in product design quality, life expectancy, performance and cost play a more important role.

CAE technology mainly uses the finite element method, the simulation technology, the optimized design. CAE technology application almost runs through the whole process of car design, in modern automotive product design to play the color is more and more important.

2. CAE simulation technology in the automotive industry an important role

1) CAE technology can simulate the performance and condition of components and even the vehicle before the new models are developed, and avoid the traditional design - trial-testing - improve the design-re-trial process and reduce the consumption of human, financial and material resources Development costs, so that most of the problems of automotive products can be resolved at the design stage through simulation, thereby improving the design quality and efficiency, greatly reducing the product development cycle and costs;

2) CAE technology has changed the traditional design to rely on the experience of qualitative analysis, the lack of quantitative data design methods, the use of CAE means to make the product weight loss, performance optimization; the same time, using CAE calculation can be more in a short time to compare more programs, Get better and even optimized design to improve the quality of development; can also find the real cause of design problems, design engineers to provide changes in the direction to reduce the error, shorten the development cycle;

3) The application of CAE technology makes some knowledge of experience in the past design can be saved and reused in the form of quantitative, convenient and convenient. CAE technology can provide design engineers with a lot of simulation test data and technical parameters to increase the enterprise's Experience the accumulation of knowledge to enhance the design of the automotive industry capacity;

4) CAE technology enables design engineers to pre-evaluate the structure and performance of the vehicle during the product design phase, thereby significantly reducing the risk of new models. At the same time, CAE technology can significantly reduce the number and cost of tests, and some can replace test.
