    摘要:

    在传统的矿用车液压制动系统理论基础上,在安全情况下,基于混合动力矿用车再生制动能量回收最大化,提出了一种后轮并联混合矿用车再生制动力分配与再生制动控制策略。主要考虑电机发电效率、电池的SOC值及制动力分配等综合因素对再生制动能量回收的影响,运用ADVISOR进行整车建模和典型矿山制动工况下仿真。结果表明:制动初速度为15 km/h,制动强度Z分别为0.1、0.3、0.5的最大再生制动能量回收效率分别为65.01%、55.99%、46.41%。采用后驱并联混合矿用车再生制动控制策略解决制动安全性能问题,并实现最大化再生制动回收效率。

    Abstract:

    Based on the theory of hydraulic brake system of traditional mining vehicles, under the safety situation, based on the maximum recovery of regenerative braking energy of hybrid mining vehicles, a regenerative braking force distribution and regeneration system for rear-wheel parallel hybrid mining vehicles is proposed for dynamic control strategy.Mainly considering the effects of motor power generation efficiency, battery System and Organization Control(SOC) value and braking force distribution on the recovery of regenerative braking energy, ADVISOR was used for vehicle modeling and simulation under typical mine braking conditions.The results show that the maximum regenerative braking energy recovery efficiency at the initial braking speed of 15 km/h and the braking strength Z of 0.1, 0.3, and 0.5 is 65.01%, 55.99%, and 46.41%, respectively. The regenerative braking control strategy of the rear-drive parallel-mixing mining vehicle is used to solve the problem of braking safety performance and to maximize the recovery efficiency of regenerative braking.
