摘要

本文首次提出了求解四阶板弯曲振动问题的无网格倒向代换法。数值解由边界条件的近似和由控制方程用配点法得到的带加权参数的齐次修正基函数组成。关键问题是初始逼近的组织和由传统基函数导出的修正基函数。为了证明所提方法的准确性和有效性,进行了几个数值算例,并与文献中已有的方法进行了比较。数值实验结果验证了该方法在精度和效率方面的潜力。

Simulation of plate bending vibration problems by the meshless backward substitution method
In this paper, the meshless backward substitution method is proposed for the first time to solve the fourth-order plate bending vibration problems. The numerical solution consists of approximation from the boundary conditions and the revised basis functions which satisfying the homogeneous conditions with weighted parameters which are obtained from the governing equations by the collocation method. Then the key issues are the organization of initial approximation and the revised basis function derived from the traditional basis functions. To demonstrate the accuracy and validity of the proposed method, several numerical examples are conducted and compared with existing methods in literature. The obtained results from numerical experiments confirm the potential of the proposed method in terms of both accuracy and efficiency.
