Design and Simulation of Thermal Management System for Electric Mine Transport Vehicle

为解决矿山作业高温环境下工程车辆热管理散热与驾驶室舒适性问题,对某电动矿山运人车整车热管理系统与控制策略开展设计研究。针对矿山运人车热管理需求特点,对整车驾驶室、电池、电机三大系统提出独立冷却系统设计方案与控制原则,完成核心系统部件的选型匹配与仿真模型构建。结合AMESim与MATLAB/Simulink软件建立了比例积分微分(PID)控制器和模糊PID控制器,并在不同外界温度与车速工况下开展了联合仿真分析,仿真结果表明,模糊PID控制反应灵敏,超调小,能将驾驶室温度更加平稳地控制到目标温度,满足设计要求。该热管理系统设计可为今后矿山工程车辆热管理系统智能化提供一种设计思路。

The design and study of the whole vehicle thermal management system and control strategy of electric mine carrier vehicles are carried out to solve the problem of heat dissipation and cab comfort of engineering vehicles under outside high temperature environment.According to the characteristics of thermal management demand of mine transport vehicle,the design scheme and control principle of independent cooling system are proposed for the whole vehicle cab,battery and motor,and the matching of core system components and the construction of simulation model are completed.The proportional integral differential(PID)controller and fuzzy PID controller are established by combining AMESim and MATLAB/Simulink software,and the joint simulation analysis is carried out under different external temperatures and vehicle speeds.The simulation results show that the fuzzy PID control response is sensitive,the overshoot is small,and the cab temperature can be more steadily controlled to the target temperature,meeting the design requirements.This thermal management system design can provide a design idea for intelligent thermal management system of mine engineering vehicles in the future.
