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 approach about damping shock response for suspension system structure. It started from Lagrange Equation in analytical dynamics. The solution was presented with Longe-Kuta method and was 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 tend to be even along the structural height. The inter- storey drift, velocity and acceleration were greatly decreased. When the radius is in the range of 3m for the reasona- ble value,the s suspension system damping shock efficiency could reach 75% -86%.
