| 摘 要： | 为分析全地域移动平台的振动特性,建立了10自由度半车刚体振动模型.整车振动模型的求解采用时域法,模型激励为路面随机输入位移信号.按照路面不平度功率谱,采用三角函数法来生成路面随机位移数据.利用建立的10自由度整车刚体振动模型,分析了车架弹性振动的影响,结果表明车架的1阶、2阶弯曲对整车振动的影响较大,更高阶的弯曲对整车振动的影响较小,因此在1/2整车振动模型建模中,考虑到车架的1阶、2阶弯曲已能满足精度要求,能很好地分析整车振动.最后结合ISO2631-1对人体振动的评价方法,分析了驾驶员处的振动舒适性.

| Abstract: | In order to assess the vibration performance of all terrain vehicles,a half vehicle model with 10 degrees of freedom was built.The model was solved using the time domain method.Road surface irregularity excites the model and was generated by a trigonometric function.Based on this model,the beaming of the frame was analyzed.The results show that the first beaming and second beaming influence the vibration significantly.As a result,a half vehicle model that includes the first two beamings of the frame can sat... |
