摘要
基于MATLAB对二自由度系统简化为单自由度系统进行数值分析,分别讨论了线性系统中阻尼比、频率比、质量比对易损件加速度响应的影响;对易损件求解的传统方法存在误差;并提出了相应的简化条件.
This paper discusses the effect of damping ratio, frequency ratio, mass ratio on the precision of fragile reaction of linear system in the predigestion of two-degree-of-freedom dynamic system as single-degree-of-freedom system based on Matlab; The traditional calculation of fragile causes error. The corresponding predigestion conditions are presented.
