供弹机传动轴刚度有限元分析

Finite Element Analysis on the Transmission Shaft Stiffness of Feeding Mechanism

应用 I-DEAS 软件的有限元分析功能,对高炮自动机供弹系统的传动轴刚度进行了分析,同时讨论了提高传动轴刚度的方法并进行了验证计算。针对体单元节点没有转动自由度的局限,提出了一种施加Constrain 单元准确输出实体结构任意一点角位移的方法。

This paper analyses the stiffness of the transmission shaft of the feeding mechanism by IDEAS FEA software, and discussing its improvement methods, and makes verification computation. In allusion to the lack of rotation DOF of solid element, a new method of measuring the angle displacement of solid structure is also brought forward.
