采用正交多项式构造试函数并提出相应的权函数,用加权残数法中的离散型最小二乘法及伽辽金法解复杂边界和集中载荷作用的弹性薄板问题,使加权积分计算更为简便并达得较好的精度。为工程结构中板的计算,如桥面板、路面板的计算,提供了简便有效的途径。
The orthogonal polynomial is used to construct the trial function and the corresponding weight function. The weighted least square method and the Galerkin method are used to solve the elastic thin plate problem of complex boundary and concentrated load, which makes the weighted integral calculation easier And achieve better accuracy. For the engineering structure of the plate calculation, such as bridge deck, pavement board calculation, provides a simple and effective way.
