摘要:
从车辆设计及系统动力学参数优化的角度出发探索优化悬挂式单轨车辆导向性能的方法。首先对悬挂式单轨车辆结构进行分析,在此基础之上建立悬挂式单轨车辆拓扑构型关系和基于多体动力学的动力学仿真模型;然后对悬挂式单轨车辆系统动力学参数进行灵敏度分析,筛选出对悬挂式单轨车辆导向力矩影响显著的参数;最后以影响显著的系统动力学参数作为优化设计变量,以车辆曲线通过性能和平稳性作为优化约束条件,采用 NSGA-II 遗传算法作为优化算法,运用多体动力学软件(ADAMS)与多目标优化软件 (modeFRONTIER)联
Abstract:
From the perspective of vehicle design and optimization of system dynamics parameters, a method for optimizing the guidance performance of suspended monorail vehicles was explored. Firstly, the structure of the suspended monorail vehicle was analyzed. On this basis, the suspension monorail vehicle topological configuration relationship and dynamic simulation model based on multi-body dynamics were established. Then, the sensitivity analysis of the system dynamics parameters of the suspended monorail vehicle was performed, and the parameters that have significant influence on the steering torque of the suspended monorail vehicle were selected. Finally, the influence of significant system dynamics parameters was taken as the optimal design variables, the vehicle curve passability and stationarity were taken as the optimization constraints, the NSGA-II genetic algorithm was used as the optimization algorithm, the multi-body dynamics software (ADAMS) and multi-objective optimization software (modeFRONTIER) were combined to optimize the steering torque of the suspended monorail vehicle, and the effectiveness and feasibility of the optimization results were verified. The optimization results show that under the given constraints, when the vertical stiffness of the air spring, the transverse stiffness of the air spring, the vertical stiffness of the running wheel, the side-bias stiffness of the running wheel, and the radial stiffness of the guide wheel reached the optimal solution, the steering torque of the suspended monorail vehicle was reduced by 26.57%~38.57%, and the guiding performance of the suspended monorail vehicle has been effectively improved.
