本文提出了用改进的微分求积法分析圆柱壳的方法。广义微分求积（GDQ）方法与现有的微分求积方法相比，具有计算上的优势。GDQ方法已被应用于流体力学和板问题的解决方案，并已显示出高超的精度，效率，方便，在解决微分方程的巨大潜力。本文试图将该方法应用于圆柱壳问题的求解。为了说明GDQ方法的实现，确定了简支-简支、固支-固支和固支-简支边界条件的频率和基频。通过与文献中的结果进行比较，验证了所获得的结果。John Wiley & Sons，Inc.
The analysis of cylindrical shells using an improved version of the differential quadrature method is presented. The generalized differential quadrature (GDQ) method has computa tional advantages over the existing differential quadrature method. The GDQ method has been applied in solutions to fluid dynamics and plate problems and has shown superb accuracy, efficiency, convenience, and great potential in solving differential equations. The present article attempts to apply the method to the solutions of cylindrical shell problems. To illustrate the implementation of the GDQ method, the frequencies and fundamental frequencies for simply supported-simply supported, clamped-clamped, and clamped-simply supported boundary conditions are determined. Results obtained are validated by comparing them with those in the literature. © 1997 John Wiley & Sons, Inc.
