【摘要】 本文根据自由边界的特性，提出了两种非经典边界──受限自由边界。从而为处理自由边界提供了一个普遍适用的方法。根据受限自由边界的概念以及振型方程的线性性质，采用叠加法，解决了具有自由边界矩形板的动力分析这一困难问题。更多还原

【Abstract】 In this paper,according to the characteristic of free edge,two kinds of restrained free edges,which are different from classical one,have been suggested;make use of this,agneralized method for treating free edge has been developed,meanwhile,considering linear characteristic of mode shape equation,using superposition method,the difficult problem of dynamic analysis of thin rectangular plate with boundary condition of containing free edges has been solved.更多还原
