粘性介质中的长壳在冲击载荷作用下的刚塑性动力响应

Dynamic Response of Rigid—Plastic Long Shell in Viscous Medium under Impact Loading

本文研究了粘性介质中的固支长圆柱壳受均布冲击侧压时的塑性动力响应,得到了解析解,并对此解进行了讨论。当介质阻尼参数β趋于零时,本文结果与无阻尼解一致。文中还画出了阻尼参数及壳体的长度参数对长壳运动时间的影响曲线。

In this paper, the author studied plastic dynamic response of the shell of long columns on fixed supports when the shell suffered a side pressure of uniform impact loading in viscous medium. Furthermore. an analytic solution has been obtained and discussed in the paper. When the damped parameter tended to zero, the result was consistent with the non-damped case. The influence curve which showed the effect of the damped parameter and the parameter of length to movement time of long cylindrical shell was traced in the paper.
