【摘要】 本文针对工程实际中所遇到的撞击问题,在事先仅知撞击体初始速度的条件下,研究分析了半无限粘弹性Winkler地基上的弹性圆薄板受刚体撞击的动力响应问题,推导出了关于撞击力F(t)的非线性Volterra积分方程,给出了薄板位移响应W(r,θ,t)的一般表达式,并给出了相应的数值求解方法。作为实例,本文对周边固定的弹性圆薄板在圆心处受刚球撞击问题进行了分析计算,并对某些参数的影响进行了讨论。更多还原

【Abstract】 In this paper, the dynamic response problem of an elastic circular plate on a half-space viscoelastic winkler foundation impinged by a moving riged body is discussed. To analyze the problem, a non-linear volterra integral equation of impact force F(t) is deduced, and a numerical computation method is used to solve the problem. At the end ,a practical example is presented, and the effect of some parameters is studied更多还原
