摘　　要：针对纯电动动力传动研究中,单个小功率电机因动力不足、调速范围小造成电机损坏和单个大功率电机自身负载大、能量损耗大等问题。设计了一种差动式并联耦合输入单输出的差动式耦合传动试验台,研究了试验台在不同工作模式下,负载变化时,输入输出转速和功率损失的变化关系。通过仿真试验与试验台测试运行表明,当电机达到稳定运行状态时,额定功率为0.49 k W,差动式耦合传动下平均输出功率约为0.482 k W,功率损失小于10 W,调速范围增大29.17%,传动效率大于81.7%,输出动力得到有效提升且重复性好。为后续继续研究耦合传动系统的动力优化提供了试验研究平台。Aiming at the research of pure electric power transmission, the single low - power motor has the problems of low power, small speed range which can cause motor damage and the single high - power motor has the problem of large own load, large energy loss and other issues. A differential type parallel coupled input sin- gle output power transmission test bench is designed, the relationship between input and output speed and power loss when the load changed under different working modes is studied. The results of simulation test and the test bench test run shows, when the motor reaches steady state operation, the rated power is 0. 49 kW, the average output power is about 0. 482 kW, power loss is less than 10 W, speed range increases 29.17%, transmission efficiency is greater than 81.7%, output power is enhanced effectively and also has fine repeatability. The experimental research platform is provided for the further research on the dynamic optimization of the coupling transmission system.
