摘要
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 utilization rate of the motor power for electric drive tracked vehicles, based on the improved bilateral independent motor drive scheme,a driving scheme based on power cou-pling mechanism is proposed to make the steering regeneration power to flow back as much as possible in mechanical means.Models of kinematics and dynamics of the scheme are built,and the high speed side steering input and output powers are comparatively analyzed.Meanwhile,modeling simulation analysis by using RecurDyn is done to verify the feasibility of the transmission scheme of coupling mechanism.The results show that using the scheme can significantly reduce the power requirements of motor.
