摘要
本文采用变换的办法解决了加权残值法在计算任意四边形薄板问题时边界条件不易处理的困难,拓广了加权残值法在处理非规则外型固体力学问题方面的应用范围,使工程人员更易掌握板的自然频率的计算。
Dificulty that plate problems in arbitrary tetragon domain were resolved with method of weighted residuals was that boundary conditions were not precessed easily. Arbitary tetragon domain was changed into square domain with transformation in the essay. The difficulty was overcome. So a new path to calculate integrally frequencies of arbitrary tetragon plate was obtained.
