【Abstract】 In order to analyze the dynamical performance of Chinese-made high-speed maglev vehicle running on the test lines,the dynamical simulations of small radius curved-track negotiations were carried out.Based on the primary structural parameters of walking assembly,the geometric relations and forces acting between carbody and walking assembly traveled on curved-tracks are initially calculated.By the collaborative platform of multi-body dynamics and system analysis,the dynamics and control model of the full vehicle is modularly assembled,and the R=400 m curve negotiations are simulated.From the contrast analyses between the calculated and simulated values,and further the different velocity running simulation analyses of maglev trainsets,the correctness of the modularized assembling model and simulation results is proven.更多还原
