摘要:
针对某轻型客车杂合车在路试5 000 km时车架出现疲劳裂纹的问题,综合采用多体动力学、有限元和疲劳分析方法对其进行疲劳破坏仿真.在MSC.Adams/Car中建立该车的多体动力学模型得到其在B级路面的载荷历程,在MSC.Nastran中采用惯性释放方法对其进行静力学分析,在MSC.Fatigue中对其进行疲劳寿命分析,通过对结果深入研究,找到该车架产生疲劳裂纹的主要原因,提出了合理的改进方案,最后对改进后的车架结构进行了寿命对比验证.
Abstract:
Based upon the fatigue crack problems of a light-bus hybrid vehicle frame after run 5 ,000 km,a fa-tigue crack simulation is done for this with the comprehensive application of multi-body dynamics,finite ele-ment analysis and fatigue analysis.A multi-body model is set up in MSC.Adams/Car with load spectra of B-grade road acquired,a static analysis is conducted by using inertia relief technique in MSC. Nastran,a fatiguelife analysis is performed in MSC.Fatigue, the main reasons that lead to fatigue breach is analyzed to find out.One measure is proposed to pick out according to demand. In the end,the verification of the modified modeland the comparison of the fatigue life between the prior and the modified project was done.
