非线性振动及货车运行安全性分析
Analysis of the Nonlinear Vibration and Safety of Freight Vehicle
【摘要】 利用NUCARS软件,详细计算了C62货车的动力响应,并利用时间历程曲线、相平面图和功率谱密度曲线对C62货车的霍普夫分叉、极限环、倍周期分叉和混沌运动进行了研究,给出了C62货车的分叉图.在此基础上,对我国目前货车运行安全性进行了探讨.
【Abstract】 Using the NUCARS software,the dynamic responses of the C62 freight vehicle have been calculated. The Hpf bifurcation, limit cycle and chaos motion of C62 freight vehicle have been invested by the time history curve, phase plan and power spectral density. The bifurcation of C62 freight vehicle is taken out. Based on the bifurcation, the running safety of C62 freight vehicle is discussed.
