【摘要】 本文中提出了一种对Benfield混合界面模态综合法的模态修正方法,从而提高了Benfield方法的求解精度,并且克服了由日本学者长松昭男所提出的修正方法中聚缩系数的取值没有准则可循的困难,通过算例表明,这一模态修正方法所得到的结果是很好的——其计算精度比固定界面模态综合法的计算精度还好一些。更多还原

【Abstract】 A revised mode method for the Benfield mixed-interface mode synthesis method is presented in this paper. This method improves the accueracy of the Benfield method and overeomcs the difficulties in Akio Nagamatsu’s revised method in which there isn’t any rule to choose the reduced coefficient. It is shown inexam-ples that the accurate calculation result by the revised mode method are better than those by fixed-interface mode synthesis method and the CPU time isalso reduced,更多还原
