Research on Stabilily Simulation for Straddle-type Monorail Vehicle

在多体动力学理论的基础上,参照重庆市跨坐式单轨车辆动力学相关参数,运用SIMPACK动力学仿真软件建立了跨坐式单轨车辆的整车动力学仿真模型,并进行了仿真。根据Sperling车辆平稳性评价标准经验公式在MATLAB中编制相关程序,把SIMPACK仿真结果曲线导入MATLAB中进行计算。计算结果表明重庆市跨坐式单轨车辆有较好的运行平稳性。

Based on multi- body dynamics theory and consulted interrelated parameters about the dynamics of chongqing straddle - type monorail car, the paper established straddle- type monorail vehicle model and simulated it by using dynamics simulation software-SlMPACK. According to evaluated standard experiential formula studing on sperling vehicle stability, relevent programmes based on MATLAB have been gained, and simulated result curves on SIMPACK have been imported into MATLAB to be calculated. Eventually, the calculating results indicate that ChongQing straddle - type monorail car has favorable running stability.
