Based on the ANSYS, the model analysis has been made on the base of PYQ202C Press Machine .
基于ANSYS软件,对PYQ202C平压压痕切线机机座进行了模态分析。
The optimum design method is applied in PC base in this paper.
对PC机机座进行了最优化设计 ,建立了以机座弹跳值与机架质量的加权和最小为目标函数 ,包括 7个设计变量 ,2 2个约束条件的优化设计数学模型 。
So the dynamic stiffness of the base can be increased and also the production cost can be reduced through improving the wall thickness t1.
基于ANSYS软件 ,在对动态灵敏度分析原理研究的基础上 ,以机座外壳四周壁厚t1 和工作面板厚度t2 作为设计参数对PYQ2 0 2C平压压痕切线机机座进行了动态灵敏度分析。
