环与杆高速碰撞动态响应的分析和预测

Analysis and Forecast of Dynamic Response on a Conical Ring Impacting a Long Bar

采用量纲分析的方法 ,讨论了环与杆高速碰撞时影响杆被击断的主要因素 ,分别给出了相对临界速度、临界方位角及环的临界厚度与主要物理参数的函数关系 ,并通过计算机仿真确定这种函数关系。

Based on the dimensional analysis, this paper deals with the main influential factors of the bar-ring impact with high speed. The functional relations between the critical relative impact velocity, critical orientation angle and critical thickness of conical ring and the influential factors are established by numerical simulation.
