模态综合技术是一种动态子结构法,它是分析大型复杂结构主要模态特性的有效手段之一。这种方法首先在宇航工程领域中获得广泛应用,目前已普及应用于滨海结构、机械和民用建筑等重大工程部门。基本途径是将系统分划成一些较小的部件(或子结构)集,它们之中每一个都能在指定的计算机上预测其主要的模态参数,或用试验方法测量到这些参数,而完整系统的响应可通过综合各个部件的动态特性取得。
Modal synthesis is a dynamic substructure method, which is one of the effective methods to analyze the main modal characteristics of large and complex structures. First of all, this method has been widely used in the field of aerospace engineering and is now widely used in major engineering departments such as coastal structures, machinery and civil buildings. The basic approach is to divide the system into smaller sets of parts (or substructures), each of which can predict its dominant modal parameters on a given computer or measure these parameters experimentally The response of the complete system can be obtained by synthesizing the dynamic characteristics of the various components.
