摘要
针对某型轿车变速器悬置支架在道路试验中失效的现象,提出了有效的解决方案。建立了悬置系统动力学模型,进行动力学仿真分析并获得载荷数据。进而应用有限元方法对变速器支架进行分析;根据分析结果,使用连续体结构拓扑优化技术对支架模型进行优化设计;结合台架试验和疲劳寿命预测对变速器悬置支架疲劳寿命进行分析以验证改进方案的有效性和可靠性。
Aiming at the failure of transmission mount bracket of a model of car, a dynamic model for powertrain mount is set up and a dynamic simulation is conducted to get the loading data. Then based on these data a finite element analysis and a corresponding continuum structure topology optimization on transmission mount bracket are performed. Finally, both the rig test and fatigue life prediction are carried out to validate the effectiveness and reliability of optimized design of transmission mount bracket.
