摘要
应用三维有限元动力学的基本方法 ,结合Newmark积分方法逐步求解运动方程 ,对移动点荷载作用下温克勒地基上板的变形和应力响应进行了分析 .计算了路面的固有频率、临界速度 ,讨论了荷载速度、板参数、地基参数对最大动挠度和拉应力的影响规律 .
Dynamic response of rectangular plates on viscoelastic foundation layered pavements subjected to moving point loads is analyzed by using the three-dimensional(3D) finite-element method in conjunction with Newmark integration scheme.Natural frequency and critical speed are gained.The variations of the calculated value of deflection and tensile stress depending on the moving speed,physical parameter of plate and subgrade are given.
