Embodiment Construction

[0037] The multifunctional movable barrier and the modeling method of the automobile collision simulation analysis of the present invention are developed with genuine software such as Ls-Dyna, Hypermesh as a platform. During the modeling process, the center of gravity position, mass, collision angle, collision speed, and stiffness of the honeycomb energy-absorbing block of the movable barrier are all parametrically designed, and the corresponding data can be input according to the purpose of the movable barrier, which can be directly entered into the software The program calculates the corresponding result. The present invention can improve calculation accuracy and analysis reliability in collision simulation analysis and calculation, improve calculation convergence and shorten calculation time, is beneficial to define contact, and can prevent crashes or exit from calculation in collision simulation analysis and calculation. With the rapid development of my country's automobil...

Abstract

This invention relates to a kind analytical procedure of automobile collision multifunction emulation and removable counterguard. The invention includes: found removable counterguard model; define removable counterguard's car frame, tyre, subpanel as rigid body of nonoccurrence distortion and relative displacement; build removable counterguard's upper and down beehive absorbing model on described subpanel, and set the correlative size of removable counterguard as specific model parameter; carry in real vehicle parameter corresponding to removable counterguard's model parameter; thereby utilize state removable counterguard to emulate need measuring vehicle to carry out vehicular different kinds of collision test analysis. This invention can advance computational accuracy and analyses reliability, and advance calculation astringency and short calculation time.

Description

technical field [0001] The invention relates to automobile collision simulation technology, in particular to a multifunctional movable barrier and a modeling method for automobile collision simulation analysis. Background technique [0002] At present, the car crash simulation tests done by domestic car companies and research institutes lack a multifunctional movable barrier, which can not only do a variety of car side collision simulation tests, but also can do car traffic accident reproduction simulation tests. . The movable barriers in the existing foreign crash simulations are single-purpose. For example, the movable barriers used in Europe can only be used for the ECE R95 side impact test. And there is not a kind of movable barrier at home and abroad that can be used as the vehicle causing the accident in the simulation test of the reproduction of the automobile traffic accident, and needs to spend a lot of time and energy to set up the model of the vehicle causing the...
