Abstract: Each section of the traditional straddle monorail train was carried by two bogies body. In order to reduce the number of bogies and realize the lightweight design of straddle monorail, a new type of three-module articulated straddle monorail was designed by integrating the structure of straddle monorail and the characteristics of articulated monorail. The dynamics model was established based on the dynamics simulation software SIMPACK, and the simulation experiments on the stability performance of the model under no-load condition were carried out at three different speeds through the radius 100m curve. The simulation results show that the three module articulated straddle monorail trains run well at 3 different speeds through the radius 100m curve, but the operation stability of the train becomes gradually worse with the increase of speed.
