摘要

Abstract

The coupling vibration problem of the straddle type monorail-flexible track beam system is very complex

involving numerous sensitivity factors

and many issues need further research. The safety and comfort of the dynamic operation of the formation train are crucial for the safe operation of the rail vehicle. Based on the multi-body dynamics theory and Timoshenko beam theory

this paper derives the dynamic models of the straddle type monorail train and the flexible track beam respectively. At the same time

the tire model is accurately considered

and a refined coupling dynamic model of the straddle type monorail flexible track beam is established. We studied the comfort performance of the coupling system between a straddle type monorail train and a flexible track beam under the influence of factors such as track roughness and support parameters

and evaluated the calculation results based on the comfort evaluation system constructed in this paper. This provides theoretical support for the safety design and vibration control of the coupling system between the straddle type monorail train and flexible track beam.
