为提高电传动履带车辆的电机功率利用率,在改进双侧独立电机驱动方案的基础上,提出了一种基于功率耦合机构的驱动方案,使转向再生功率尽可能通过机械方式回流。建立了该方案的运动学和动力学模型,对转向时高速侧输入、输出功率进行了分析比较。并利用RecurDyn进行了建模仿真分析,验证了耦合机构传动方案的可行性。结果表明:采用此方案可以显著降低转向时对电机功率的需求。
In order to improve the motor power utilization efficiency of electric drive tracked vehicles, a driving scheme based on power coupling mechanism is proposed based on the improvement of bilateral independent motor drive scheme, so as to make the steering regenerative power return through mechanical means as far as possible. The kinematics and dynamics model of the scheme is established, and the input and output power of the high-speed side are analyzed and compared. And the use of RecurDyn modeling and simulation analysis to verify the feasibility of the coupling mechanism transmission scheme. The results show that this method can significantly reduce the need for motor power during steering.
