摘    要:对只有弹性模态以及除此之外还有刚体模态的结构的瞬态响应给出了精细积分的通用公式,从而使得该方法不仅可以处理线性激励的情形,而且对激励是多项式形式或可以展开成多项式的激励也同样能够计算。对于非线性激励,只要可以用关于自变量的级数形式来近似表示,都可以用本文所给的方法进行计算,计算的精度可以通过变化级数的项数来调整。

关 键 词:动力响应  瞬态过程  时程积分  线性激励  非线性激励  结构动力学

Abstract:A high precise integration scheme for analysis of dynamical response of the structures with elastic or rigid modes is developed in the paper. The scheme can be used in the excitations with linear as well as polynomial forms. Moreover, if the nonlinear excitation can be presented in the polynomial series, the dynamic response of structure is also obtained by the proposed method, and the computed precision can be adjusted by changing the order of the polynomial.
Keywords:dynamic response  transient process  time\|integration  linear excitation  nonlinear excitation
