摘要
提出一种工况载荷定义方法,即在试验场场地内开展整车目标工况的载荷测试,采用极大似然估计法对关键参数进行威布尔(Weibull)分析,最终确定该工况载荷定义,以前悬架系统部件应力为例确定其评价指标,并开展了悬架系统承载能力实物试验和虚拟验证,结果表明,悬架系统实际承载能力满足设计目标,且虚拟验证可实现悬架系统实际承载能力的预测。
A definition method of condition load is proposed,i.e.carry out the load test of the vehicle under the target condition in the proving ground,and the maximum likelihood estimation method is used to make Weibull analysis of the key parameters,and finally determine the definition of condition load.Then,the stress of the front suspension system components is taken as example to determine its evaluation criterion,and conduct physical and virtual experiments of the suspension system load capacity.The results indicate that the actual load capacity meets the design objective of the suspension system,and virtual experiment can predict the actual load capacity.
