摘要

为更加合理地利用耐久性和设计寿命,实现机械构件的多方面优化,从履带车辆承载关重件-扭力轴的实际出发,运用Solid Works软件进行扭力轴的参数化建模,通过数据接口将模型无缝传输到Ansys Workbench软件中,以该软件为平台对参数化模型进行瞬态应力分析与耐久性疲劳分析,运用Design Exploration模块对扭力轴进行多目标驱动优化设计,将优化后的结构重新在Ansys Workbench中进行分析和验证,结果表明:优化模型满足扭力轴使用耐久性寿命,自身重量下降9.9%,验证了优化的合理性。

Abstract

Strat from the structure of torsion shaft to more reasonably use durability and design life,realize the various optimization of mechanical construction.A parameterized model of torsion shaft was developed based on Solidworks and imported into ANSYS Workbench by data interface.Transient stress and durability fatigue of parameterized model were analyzed in ANSYS Workbench.The multi objective optimization of torsion shaft was designed in Design Exploration module and the optimized structure of torsion shaft was reanalyzed in ANSYS Workbench.The result of optimization design shows that optimization model meets durability life of torsion shaft and weight decreased 9.9 percent.The result demonstrates the correctness of the optimization.
