| Abstract: | 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 semitrailer trains. |
