Popis: Abstract In this study, a new type of single-axle bogie of straddle-type monorail vehicle is designed. The tumbler structures are adopted in the vertical suspension system. One end of the tumbler is fixed to the framework, while the other end supports the framework via air springs. In addition, the lateral suspension utilizes the suspender way, with longitudinal force transmitted via single pull rods. Guide wheels and steady wheels are connected to the end support arms of the framework through spindles around the horizontal direction. Rubber springs, the pre-compressed magnitudes of which could be adjusted, are set between the spindles and support arms. The multi-body dynamics software UM is adopted to construct a dynamic model and simulate related dynamic performance. The results of the simulation indicate that this new kind of bogie has a favorable performance when passing through curves and has a greater riding stability. The flexibility factor equation of this new monorail vehicle is deduced, with its flexibility factor obtained.
