摘要
建立文克尔地基上矩形薄板自由振动和强迫振动的微分方程并求得其通解，给出振型函数的表达式及常见支承条件下板的频率方程．
Differential equations of free/forced vibrations of rectangular thin plates on Winkler′s foundation are estabilshed and their general solutions are obtained.The expression of vibration mode function and frequency equations for usual supports are deduced.The forced vibration responses of such plates under different type loads are discussed by using generalized functions. \ \
