汽车稳定杆拟动态实验分析

Simulated Dynamic Analysis for Automobile′s Stable Pole

本文主要通过汽车稳定杆在疲劳试验中应力、刚度拟动态试验,采用电测法[1],在分析杆件中实际应变和位移的基础上进行逆解分析,从而确定稳定杆的实际刚度,支座摩阻反力矩和应力集中系数,为建立稳定杆的简化力学分析及其疲劳寿命预测提供试验依据.

The real rigidity, the frictional moment of support and the stress concentration factor of stable pole are analyzed and determined through the stress and rigidity simulated dynamic test in fatigue experiment by using the method of electronic measurement. The reverse analysis method is used based on the real strain and displacement that we have acquired. The results are valuable for simplifying the mechanics analysis and predicting its life span.
