以工程振动理论为基础建立矩形板的冲击动力学响应的粘弹性地基板数值计算模型,运用薄板横向振动的基本微分方程和三角函数级数展开法对常速运动面荷载作用下粘弹性地基板进行了分析,求得了板的动力响应的解析解,该模型能用来模拟移动冲击荷载作用于薄板时的动力反应、分析评价基板屈服状态。

Engineering vibration theory is used to create dynamic response numerical model of viscoelastic grade slab of rectangular flatplate, basic differential equation of thinplate cross vibration and series expansion of trigonometric function are utilized to analyze viscoelastic grade slab on uniform moving speed area load, and the analytic solution of plate dynamic response function is thus obtained. This model can be used for simulating thinplate dynamic response on moving impact load and analyzing the yield status of based plate.
