| 摘 要： | 本文应用复模态理论和线性系统振型迭加原理,采用原坐标分析法,建立了一般粘性阻尼多自由度系统对任意激振力的瞬态响应的新的数学模型,并编制了相应的计算机程序。本文所建立的方法和程序,既可以用来求解系统的位移瞬态响应,又能用来直接求解系统的弹性力(或弹性力矩)的瞬态响应。该程序已用于工程实际计算,得到满意的结果。

| Abstract: | Based on the theory of complex modality and the superimposition principle of linear vibratioonal patterns,and in the approach of primitive coordinate analysis,a new model for finding instantaneous response of generalized multi-DOF viscous damper system acted on by an arbitrary exciting force is established; the corresponding computer program is compiled. The proposed approach and program can be used to find directly the instantaneous elastic force (or elastic force moment) response in the system. The program has found satisfactory application to actual calculations in engineering problems. |
