摘要:

针对露天矿自卸车传统机械式传动系统与串联式电传动系统存在的动力性不足、燃油经济性不佳等问题,提出了一种适用于百吨级双桥刚性矿用自卸车(简称“矿卡”)的功率分流(PS)型混合动力系统及其确定性规则动力切换控制策略。利用MATLAB/Simulink与CRUISE软件搭建PS型混合动力矿卡联合仿真模型,进行了整车动力性与经济性仿真试验。研究结果表明:在纯电驱动模式与柴-电混动模式下,所设计的双行星齿轮排传动系统的最大等效应力、等效弹性形变、安全系数等均在材料的许用范围内,在结构上可满足机械传动要求;太阳轮、行星轮与齿圈之间的啮合力变化在时域上总体呈现正弦波形,符合行星齿轮传动变化规律,在频域上幅值变化均匀,满足传动系统稳定运行要求;改造后的PS型混合动力矿卡的最大车速可达63 km/h、最大爬坡度为32%、上下坡综合油耗为288 L,比原车型分别提高了26%、60%和17.7%。

Abstract:

Aiming at the problems of insufficient power and poor fuel economy in the traditional mechanical or series electric transmission systems of open-pit mine dump trucks, a PS hybrid power system and the deterministic rule power switching control strategy suitable for 100 ton double bridge rigid mining trucks were proposed. The PS type hybrid power mining truck joint simulation models were built by using MATLAB/Simulink and CRUISE software, and vehicle power and economy simulation tests were conducted. The results show that in both pure motor driving mode and diesel engine-motor hybrid mode, the maximum equivalent stress, equivalent elastic deformation, safety factor, etc. of the designed dual planetary gear transmission system are all within the allowable ranges of the materials and may meet the requirements of mechanical transmission structurally. The variation of meshing force between the sun gear, planetary gear, and ring gear shows a sinusoidal waveform in the time domain, which conforms to the variation law of planetary gear transmission. The amplitude changes uniformly in the frequency domain, which may meet the stable operation requirements of the transmission systems. The modified PS type hybrid mining truck has a maximum speed of 63 km/h, a maximum climbing slope of 32%, and a comprehensive fuel consumption of 288 L for uphill and downhill, which has increased by 26%, 60%, and 17.7% respectively compared to the original vehicle model.

Key words: hundred-ton mining truck, power split(PS) type, hybrid power system, dual planetary transmission, control strategy
