Design And Simulation On The Side Crashworthiness Of Automotive Body

With the Chinese cars as well as the rapid increase in the rapid development of high-grade highways and improve vehicle performance as the passive safety related to the important task of thousands of households. China has set a positive vehicle collisions, side collisions, as well as the three-car collision after collision mandatory national standard system, which is to increase and improve our car's passive safety played a positive role in promoting. FAW Group B in a combined class of vehicle development, the following problems have been studied and made some research:·details of the July 1, 2006 in the domestic implementation of the "side-car collision Restraint," a mandatory national standard, analyzed and compared, the United States and Europe in the three-car side of the collision regulations of the difference.·introduced to enhance the security side of the vehicle and carry out engineering design: from the car to start the development process through the body in white, decorated inside and outside, security configuration, and so on the various aspects of engineering design, to ensure that new high passive safety, Analysis of the collision into the body and improve the safety requirements.·the establishment of a model's side-impact model and in accordance with the ECE R95 regulations on the car body for assembly of the side-impact analysis of the simulation, and real vehicle collision with the test data were compared. Simulation results to a large extent consistent with the test results to verify the consistency between the two. On this basis, the results of the simulation and test for the existing problems are discussed, analyzed the various sub-systems to improve the side of the body of the anti-collision performance, put forward a program to improve the optimization and improvement program for the second Simulation.This article from the mechanical theory of elastic-plastic finite element method and the starting point for analysis of the simulation analysis of the theoretical contents, car body-building side of the anti-collision of the evaluation. TNO Netherlands use of the company's software MADYMO set up a car body parts of the main finite element simulation of mathematical models and corresponding data processing and simplified;In this paper, the establishment of the simulation model, simulation model verification and simulation model to improve the process of summing up the establishment of a simulation model and simulation model to improve the methods and experience to explore a feasible and effective procedures, the results of other similar models on the side Anti-collision analysis of a certain reference.
