In this paper,the influence of marshalling form on the dynamic performances of floating low-floor tram is studied.Firstly,the marshalling form,bogie structure and articulated device of the floating low-floor tram are presented.Then,the dynamic models of the whole vehicle and the articulated devices are established by Simpack.Finally,the stability and curve passing performance of the train under different working conditions are compared and analyzed.The results show that the maximum difference of the stability indexes between five-module and seven-module low-floor trams does not exceed 10%.The curve passing ability of the seven-module train is worse than that of the five-module train,but they all meet the requirements of relevant standards.
