摘要
为提高无动力下坡能量回收效率,优化巡检机器人的性能指标,提出了一种能量回收最优原则的无动力下坡系统参数匹配方法。在建立无动力下坡系统理论模型的基础上,分析了系统重要参数对能量回收效率的影响。以满足最大速度、爬坡性能、回收总能量要求为前提,分别确定了电机的有效功率、减速器的减速比以及超级电容器容量的取值范围;以提高能量回收效率为目标对各个参数进行了优化选取。通过ADVISOR软件建立巡检机器人仿真模型,并对参数匹配结果进行了仿真分析。结果表明,在给定的下坡档段循环工况下,无动力下坡能量回收效率提高了7%。
In order to improve the efficiency of energy recovery of unpowered downhill and optimize the performance indicators of inspection robot,a parameter matching method of unpowered downhill system with optimal energy recovery principle is proposed.Based on establishing theoretical model of unpowered downhill system,the influence of important parameters of system on the efficiency of energy recovery is analyzed.As a precondition to meeting the maximum speed,climbing performance and total recovered energy requirements,the value range of the effective power of the motor,the reduction ratio of the decelerator and the capacity of the super capacitor are determined respectively.Various parameters are selected for the purpose of improving energy recovery efficiency.The simulation model of inspection robot is established by ADVISOR software and the simulation results of parameter matching are analyzed.The results show that the efficiency of energy recovery of unpowered downhill is increased by 7%under the given downhill cycle conditions.
