微分求积法在工程结构动力学中的应用研究
Application of Differential Quadrature Method in Engineering Structural Dynamics
摘要
Abstract
This research has proved that the differential quadrature method is equivalent to the finite difference method of the highest accuracy and explicit expressions of differential quadrature weight coefficients are derived.How to apply the differential quadrature method to the partial differential equation of engineering structural dynamics has also been stud-ied.Numerical examples are given to illustrate the procedure of using the differential quadrature method to solve dynamic partial differential equations,and differential solution and analytical solution were compared,which justfied the validity of the differential quadrature method.The above research results show that the differential quadrature method is a simple and efficient method for studying the dynamics of engineering structures with high accuracy,and it is very convenient for pro-gramming.关键词
