一种基于整车道路载荷谱的低成本零部件结构耐久性试验方法

The Durability Test Method of the Low-cost Component Structure based on the Vehicle Road Load

为提高零部件与整车结构耐久性能设计的相关程度,提出一种基于试车场实际道路载荷谱时频域转换及试验加速理论的零部件结构耐久性能试验方法,可满足自主开发中零部件结构耐久性能试验的高质量、低成本要求。

In order to improve the correlation of the component and vehicle structure durability design, a durability test method of the component structure based on the actual road load time-frequency transition and test acceleration theory. It can meet the requirement of the high quality and low cost of the component structure durability test during the independent development.
