摘要
根据路试采集的载荷谱,制定台架试验方案,利用有限元法与试验法考查某开发车型框架式驾驶室的疲劳耐久性,并将结果与对标车比较;仿真与试验结果吻合,共同考核出该车型的设计薄弱环节.最后,提出一种将加载力的下降速率曲线作为指标来评价驾驶室当量寿命的全新方法.
According to loading spectrum collected in the road test, the bench test was designed. Fatigue life simulation and test of a frame-type heavy truck cab were conducted, and the results were compared with those of the benchmark. The results of simulation and test were comparable, and the design weaknesses were checked out. Finally, a new method was proposed that force decreasing rate was regarded as an indicator to evaluate cab＇s equivalent life.
