重型卡车金属结构件可靠性设计变量控制方法研究

Research on Control of the Design Variables of Heavy Truck Metal Structure Part Based on Reliability Index

文章以重型卡车金属结构件为研究对象,提出了金属结构件特征可靠性指标的概念。以某推力杆可靠性设计为例,介绍了基于特征可靠性指标,利用载荷谱、金属结构件材料P-S-N曲线进行金属结构件设计变量控制的方法。

This paper takes metal structure parts of heavy truck as the object of study.We put forward the characteristic reliability concept.Taking the reliability design of thrust rod as an example,this paper analyzes how to combine load spectr-ums and P-S-N curve to control the design variables based on the characteristic reliability index of the metal structure part.
