Abstract

A nonlinear dynamic model of monorail vehicle and a finite element model of “running wheel-rail beam” system is established respectively, which is integrated into the Modefrontier platform. The total friction work and friction work deviation value are proposed as indicators for evaluating the wear and partial wear of the running wheels. Taking the total friction work and friction work deviation as the goals, the stability and curve passing performance of the monorail vehicle as constraints, and the structural parameters and dynamic parameters of the monorail vehicle as the optimization variables, an optimization model of partial wear of running wheel was established. The structural parameters and dynamic parameters of monorail vehicle are optimized through improved genetic algorithm. The analysis results show that the two indicators of the total friction work and friction work deviation value of the running wheels both decreased. Among them, the total friction work of the front right and rear right running wheel with severe partial wear was reduced by 20% and 21.2% respectively, the friction work deviation value was reduced by 19.30% and 27.2% respectively. The partial wear of the running wheel is improved significantly, and the purpose of reducing the partial wear of the running wheel is achieved.

基于多体动力学模型的单轨车辆运行轮磨损参数优化研究

分别建立了单轨车辆非线性动力学模型和“行轮轨梁”系统的有限元模型，并将其集成到modelfrontier平台中。提出了总摩擦功和摩擦功偏差值作为评价行走轮磨损和部分磨损的指标。以总摩擦功和摩擦功偏差为目标，以单轨车辆的稳定性和通过曲线性能为约束，以单轨车辆的结构参数和动力学参数为优化变量，建立了行走轮局部磨损的优化模型。采用改进的遗传算法对单轨车辆的结构参数和动力参数进行了优化。分析结果表明，行走轮的总摩擦功和摩擦功偏差值两项指标均有所降低。其中，严重局部磨损的右前、右后行走轮总摩擦功分别减小20%、21.2%，摩擦功偏差值分别减小19.30%、27.2%。明显改善了行走轮的局部磨损，达到了减少行走轮局部磨损的目的。
