摘要
对火炮变齿距断隔螺纹机构进行动力分析,考虑了螺齿间存在间隙的弹性支承,提出了简便的接触判断办法。实例计算和模型实验的结果基本一致。本文为变齿距断隔螺纹机构的强度校核提供了比较精确的应力计算方法。
The dynamical stresses of the bolt of broken-screws simplified as plane model are calculated by Wilson-θ method, and basically coincided with the experiment of the model. The bolt is called the bolt of unequal pitches; also the elastic boundary condition is considered.
