基于虚拟载荷的悬架台架耐久试验方法

A Bench Test Method for Suspension Durability Based on Virtual Load

为加速试验认证周期、降低试验成本,采用了基于多体动力学的虚拟载荷生成方法及其数据处理流程,搭建了悬架系统道路模拟试验台架,分别进行了基于虚拟载荷和基于试车场真实载荷的耐久试验。通过耐久试验零件失效模式与失效发生时间的对比分析,验证了基于虚拟载荷的悬架道路模拟试验方法的有效性。

For speeding up vehicle test and validation cycles and reducing test cost,a virtual load generation method based on multi-body dynamics and its data processing procedure are adopted,a test bench for road simulation of suspension system is built,and durability tests based on both virtual load and the real load of proving ground are conducted respectively.The comparative analysis on the mode and occurring time of suspension part failures in durability tests verifies the effectiveness of suspension road simulation test method based on virtual load.
