摘要
研究了具有牵引悬置装置的精密仪器设备半挂运输列车的振动问题,建立了14自由度的动力学模型并进行振动模态分析,在此基础上,计算了某典型半挂运输列车在有阻尼和无阻尼情况下的固有频率和振型.
By analyzing the vibration of a precision equipment semi-trailer train with suspending-type traction device, a 14-degree-of-freedom dynamical model is established for modal analysis. On this basis, the first six natural frequencies and modes of a typical semi-trailer train are calculated under both the undamped condition and the damped condition, which offer some theoretical references for the design of precision equipment semi- trailer trains.
