摘要
采用微分求积法求解输流管道的固有频率.研究了两端弹性支承管道的横向振动,建立了管道横向振动的微分方程,为了避免复杂边界带来的计算困难,用微分求积法求解了系统的固有频率,并与分离变量方法和文献结果相比较,验证了该算法的准确性和高效性.
The differential quadrature method （ DQM ） is extended to solve the natural frequencies of pipe. The transverse vibration of the pipe with complex restrictions is investigated, and the equations of the transverse vibration is established. To avoid complicated calculation the DQM is applied to calculate the system natural frequencies. By comparing the results of differential quadrature method and separated variables method, the high precision and efficiency of DQM is proved.
