【摘要】 本文应用结构动力学和板壳力学的理论，就位于具有两个基床系数的弹性地基上的正交各向异性板这一较一般情况，从不考虑移动荷载质量和考虑移动荷载质量两个方面进行动力分析，研究了板结构在移动荷载作用下的动力反应问题。推导出动力挠度、动内力及其动力影响面方程的计算公式和计算方法，并讨论了共振条件和移动荷载运动的临界速度，为更精确设计在移动荷载作用下的板结构提供了理论依据。更多还原

【Abstract】 On the bases of the theory of structural dynamics and mechanics of plates and shells,the dynamical analysis of the specifical orthotropic plates on the elastic foundations,which have two modulus and are traversed by light moving loads or heavy moving loads,is presented in this paper. The dynamic response of the plates under moving loads is studied. The computative formulas and methods of dynamic deflection,dynamic internal forces and equations of dynamic influence surfaces are suggested. The conditions of respnance and critical velocities are discussed and the theoretical foundations of more refined plate’s design are given.更多还原
