悬挂系统减震效果分析

Analysis for suspension system damping shock effect

根据拉格朗日方程推导了悬挂系统减震的动力反应分析计算公式,并根据龙格-库塔方法,利用MATLAB语言编制程序求解。分析与计算结果表明：悬挂系统具有明显的减震效果,楼层位移沿结构高度分布趋于均匀,层间位移、楼层速度及楼层加速度大幅减小。当悬挂结构系统半径为3m左右时,减震效果可达75%~86%。

A theoretical analyzing approachs about damping shock response for suspension system structure. It star- ted from Lagrange Equation in analytical dynamics. The solution was presented with Longe-Kuta method and pro- grammed with MTALAB software. Results show that damping shock system could exhibit significant seismic mitiga- tion efficiency for suspension system structure. The storey drift tends to be even along the structural height. The in- ter-storey drift, velocity and acceleration were greatly decreased. When the radius is in the range of 3m for the rea- sonable value, the suspension system damping shock efficiency could reach 75% ~ 86%.
