| 摘 要： | 针对组合机身压力机的结构特点 ,采用自由界面模态综合法进行振动分析 ,为使计算模型符合由拉紧螺栓实现各组合部件间弹性连接的实际结构 ,形成了弹性连接刚度阵 ,并对相关结构的刚度阵进行了修正 ,用该模型对一新型双击式螺旋压力机进行了计算 ,计算得到的固有频率与实测值相符。

| Abstract: | In this paper, vibration analysis of a new double strike screw press has been given based on the structural characteristic of its combined frame by using free boundary modal synthesis method By forming elastic coupling stiffness matrices and correcting stiffness matrices of relative substructures the computation model is made to correspond with actual structure with elastic coupling The theoretical results of natural frequency are in good agreement with the experimental ones |
