摘要
从板梁组合构件的虚功方程出发,对板采用 Adini 元插值,对梁采用三次 Hermit 插值的有限元法,作离散化处理,推导出板梁组合构件的刚度矩阵与质量矩阵,从而求得板梁组合构件的固有频率。
This paper begins with the inaginary equation of plate—grinder components,then disperses The plate and grinder by using Adini and Hermit inserts,and finally results in the intrinsic frequenly of plate—grinder components.
