推导出位移模态和应变模态的换算公式，改进了现有的残余力向量法，使之在工程实际应用中有更现实的意义。 - Based on structural dynamics , different damage diagnosis index , such as modal frequency variety , modal assurance criterion , co - ordinate modal assurance criterion , modal strain energy , remains force vector , modal strain , rigidity change , flexibility matrix , modal curvature and so on , are studied in this thesis
基于结构动力学理论,本文论述多种损伤识别指标的基本原理和计算方法,主要包括:固有频率变化率、模态置信因子、改进的模态置信因子、模态应变能、残余力向量、应变模态、刚度变化、柔度矩阵、曲率模态等。 - In this thesis a new numerical method - the finite volume method is developed to achieve the static and dynamic large - deflection response analysis for suspension cables . the finite - volume division scheme is first established along the length of the cable and the deformation of each volume is defined using the common engineering strain concept . based on this strain definition the strain energy of the cable is determined
首先建立了悬索沿索长方向的有限体积离散格式，在变形后的构形上按工程方法求得了应变，并进一步得到了应变能和动能的计算式；再根据哈密顿原理导出了悬索大挠度振动的有限体积离散方程，推出了索的整体节点力向量、质量矩阵和切线刚度矩阵。
