汽车侧面碰撞移动变形壁障试验方法

移动变形壁障是实车侧面碰撞试验时用来撞击试验车辆的标准试验工具，移动变形壁障前部的吸能块可采用不同的材料和结构，其性能对试验结果起主要影响，因此必须对吸能块及检验方法作相应规定，以保证试验结果的一致性，介绍了国外对移动变形壁吸能块性能进行考核的各种试验方法和评价要求，这些试验方法能够为我们进行侧面碰撞移动壁障的设计制造及检验提供参考。

Test Method for Movable Deformation Counterguard for Vehicle Side Impact

The movable deformation counterguard is the standard test tool in vehicle crash test to impact the test ve-hicle from side direction.The energy absorption block at the front of the movable deformation counterguard can use differ-ent materials and structures to get different stiffness,whose property has key inffluence on test results,so it is necessary to make conditions for the energy absorption block and the verification methods to ensure the consistency of test results.Vari-ous test methods and evaluation requirements for assessing performance of the energy absorption block in other countries are introduced.These test methods are references for design,manufacture and verification of the side impact movable defor-mation counterguard.
