重载列车和准高速动车组的运行,使轮轨之间的粘着经常处于极限状态,因此需要研究更先进的控制方法来优化利用粘着力。建立了包括牵引系统、控制系统和机车多体动力学模型的多学科虚拟样机仿真平台。使用机械动力学仿真软件ADAMS/Rail建立了某种电力机车的多体动力学仿真模型;利用MATLAB建立了组合粘着控制算法;通过联合仿真实现了针对机车粘着控制系统的多学科虚拟样机仿真。联合仿真平台成为了沟通粘着控制方法理论研究和试验研究的桥梁,为智能控制方法在粘着系统中的应用提供了有效的仿真环境。Abstract： With heavy-haul train and high-speed electric multiple unit （EMU） operation,the adhesion between wheel and rail often reaches limit states.Therefore the advanced control arithmetic should be studied to optimize the use of the adhesion force.A simulation platform was built including traction system,control system and multi-body dynamics model of an locomotive.The model of the electric locomotive was established with ADAMS/Rail （Automatic Dynamic Analysis of Mechanical Systems）.Then a hybrid adhesion control algorithm was designed using MATLAB.The adhesion control system can be studied with co-simulation of different simulation tools.The theoretical and experimental studies are realized with the simulation platform.It provides a new and effective ways to study the adhesion control. 相似文献
