摘　　要：某卡车空气滤清器支架在进行45 000 km耐久试验过程中时,多次出现断裂现象,通过MSC Nastran对该支架进行振动耐久分析,验证故障失效模式,提出两种改进方案,最后通过台架试验和耐久试验验证改进结构.结果显示运用有限元法能够有效的指导结构改进,节约开发成本,对于同类问题的解决具有借鉴意义.Fractures are repeatedly occurred on a truck bracket of the anti-theft alarm horn during road duration test, the duration test on bracket is analyzed using MSC Nastran. According to the analysis results, two new design examples are put forward and validated using the bench test and duration test. It is an effective method in analyzing and improving the structure design by using finite element method, and it provides a good example in solving related problems.
