【摘要】 微分求积法(DQM)是求解常(偏)微分方程的一种数值方法,在工程中得到广泛的应用。该法具有计算简便、精度较高和易于实现等优点。广义微分求积法(GDQM)是微分求积法的推广,该方法具有更高的精度和更广泛的适应性。本文通过几种刚架的实例介绍了广义微分求积法在结构动力学中的应用,突出了其简便性和通用性,为该法在工程中的广泛使用开辟了道路。更多还原

【Abstract】 Differential quadrature method(DQM),which had bean widely used in the field of engineering,was a numerical method for ordinary/partial differential equations.This method had the advantages of simplicity of calculating,high accuracy and easy implementing.Generalized differential quadrature method(GDQM) was an extension of the differential quadrature method,and had higher accuracy and wider adaptability.This paper introduced the application of GDQM in structural dynamics through several examples of rigid frame,highlighting its simplicity and versatility and opening up a wider road for the application of GDQM in the field of engineering.更多还原
