摘要: 多源驱动/传动系统广泛应用于新能源、航空航天、海洋工程等领域重大装备中,其齿轮传动装置通常由多个电动机共同驱动。针对多源驱动/传动系统在工作过程中存在的多驱动源速度与转矩不同步问题,结合其复杂耦合非线性的结构特点,提出一种以轴系单元法为基础,包含驱动电动机、齿轮传动装置和负载特性的多源驱动/传动系统机电耦合动力学模型。研究了不同载荷变化率以及电动机故障条件下对系统同步特性(速度同步、转矩同步)的影响规律。研究结果表明,载荷变化率对多源驱动/传动系统速度同步特性影响较小;但在载荷突变瞬间对系统转矩同步特性影响较大。电动机发生故障时,非故障电动机间的速度和转矩同步特性基本保持不变。该研究结果将为多源驱动/传动系统同步控制策略的制定提供理论基础。

Abstract: Multi-source driving transmission system, in which the gear transmission assembly is driven by multiple motors, is extensively used in the major equipments of new energy, aerospace, marine engineering, and other fields. Aiming at the problem of speed and torque out-sync existing in the working process of multi-source drive/transmission system, and combed with its complex coupling nonlinear structure characteristics. An electromechanical coupling dynamic model of multi-source drive/transmission system is proposed based on the shafting unit method. The driving motor, gear transmission assembly and load characteristics are considered in this model. The influence of different load change rate and motor fault on synchronization characteristics of system is investigated. The research results show that the influence of the load change rate on the speed synchronization characteristics of the system is minor, but has a significant influence on the torque synchronization characteristics. When motor fault occurs, the speed and torque synchronization characteristics between the non-fault motors remain essentially unchanged. The proposed research provides the theoretical basis for the formulation of the synchronization control strategy for multi-source driving transmission system.

Key words: electromechanical coupling modeling, load change rate, motor fault, multi-source drive/transmission system, synchronization characteristic
