考虑高载和阻尼介质时刚塑性圆板的塑性动力分析

Plastic Dynamic Analysis of Rigid—Plastic Circular Plates Considering High Load and Damping Medium

本文研究了阻尼介质对刚塑性圆板在高载(冲击荷载)作用下塑性动力响应的影响,得到了解析解并对此解进行了讨论。当阻尼介质参数趋于零时,本文结果与无阻尼解一致。文中还画出了荷载与阻尼介质对圆板运动时间和板中心点残余挠度的影响曲线。

In this paper,the author studied effect of damping medium on plastic dynamic response of rigid-plastic circular plates under high load(impact loading). Furthermore,an analytic solution has been obtained and discussed. When the damped parameter tends to zero,the result in this paper is consistent with the non-damped case. The influence curve which shows the effect of the load and the damping medium on movement time and residual deflection of central point for circular plates was traced in this paper.
