摘　　要：为了真实、全面的反应机车运行过程中粘着的动态特性和缩短粘着控制方法的优化过程,建立了包括机车多体动力学仿真模型和电气牵引控制模型的一整套机电控制虚拟样机。首先从动力学和数学角度分析了轮轨驱动关系;然后利用动力学仿真软件SIMPACK建立了完整的机车多体动力学仿真模型,考虑到了机车运行过程中的动态特性,并采用了一种自动搜索粘着峰值点的最优蠕滑速度控制方法对机车进行粘着控制;最后在MATLAB/SIMULINK建立电气牵引控制模型,通过CACE专用接口实现MATLAB与SIMPACK的联合仿真。仿真结果验证了联合仿真模型的可行性,并且轮对的空转得到了有效的抑制,在不同的轨面状况下实际的粘着系数与可利用的粘着系数几乎保持一致。机车联合仿真模型为验证粘着控制策略的正确性提供了精确的仿真平台。In order to truely and completely reflect dynamic properties of adhesion and cut down the development cycle of adhesion control methods, a full set of electrical and mechanical control virtual prototype which includes lo comotive multi body dynamics simulation model and control model of electric traction was established. First, wheel set relation was analysed based on kinetics and mathematics ; then, a complete multi body dynamics model of e lectric locomotive was established with SIMPACK and the dynamic characteristics of the locomotive was considered. An optimal creep velocity control was used which can search adhesion peak point; finally, an electric traction control model was established with MATLAB/SIMULINK. The co simulation was achieved through the CACE interface. The simulation results show that the co simulation model is feasible, the idling of the wheel set is restrained and the actual adhesion coefficient almost keeps unanimous with the available adhesion coefficient. The locomotive co simulation model supplies a simulation platform for testing correctness of other adhesion control strategies.
