32 T随车起重机吊臂有限元分析及优化

摘要

以32 T随车起重机吊臂为分析对象，以有限元分析软件的Workbench 为平台，进行强度、刚度计算，通过分析受力最危险工况，证明吊臂设计满足要求；并在平台中将一节基本臂参数化建模，以减少质量为目标函数，以满足强度、刚度要求为约束条件，对其臂厚进行尺寸优化，计算出最合理的结构，以节省生产成本。%Based on ANSYS Workbench software platform, the strength and rigidity of 32T truck mounted crane boom is calcu-lated by analyzing the force of the most dangerous working conditions , then the design of boom is proved that it can meet the requirements .Simultaneously , the parametric modeling is built for a basic arm, which established the objective function on the basis of reducing the mass, and the constraints are meeting the strength and rigidity requirements.the size of the most reasona-ble structure of the arm are calculated and optimized which could save production costs.
