【摘要】 论文是依托国家科技支撑项目“牵引传动控制策略优化研究”的子课题“黏着控制方法研究”而开展的。黏着控制性能不仅直接关系到列车设计的牵引和制动能力能否充分发挥,而且关系到列车运行的安全性,例如列车发生空转与滑行故障都是因为黏着破坏引起的。尤其是近年来我国铁路实施高速客运和重载货运,使得机车牵引负荷日益增大,因此研究如何有效利用轮轨间的黏着力,实现其优化控制具有重要的理论意义和工程实际价值。首先,本论文详细分析了机车的机械构造,采用Simpack构建转向架、车体以及轨道,分析受力情况,建立完整的机车结构模型,并完成模型初始化分析,通过仿真检验所建模型的正确性。其次,定义了SIMPACK下机车模型的输入和输出,利用MATLAB/Simulink建立机车电力牵引传动及电机控制模型。并将列车牵引传动及电机控制模型引入机车结构模型中,构建了更贴近列车实际运行工况的机车黏着控制联合仿真模型。采用国际通用的SIMPACK-MATLAB仿真工具为黏着控制方法研究搭建了一个良好的仿真平台,并成功实现联合仿真。最后,利用搭建的联仿平台,定义了具有不同黏着特性的轨面状态,结合黏着控制基本理论和现有控制方法,采用组合校正法和模糊法进行联仿,成功抑制了机车空转／打滑,改善了机车的运行状况,实现在复杂路面对机车的防空转、防滑控制,验证了组合校正法和模糊控制法的控制有效性和联合仿真平台的可用性。构建的联合仿真平台真实反映了控制效果的优劣,为新的控制策略和控制算法提供研究平台。与物理样机相比,联合仿真平台的引入降低了试验成本,缩短了开发周期,为寻求优化黏着控制提供了一种有效的研究工具。更多还原

【Abstract】 This paper is relying on the national support projects of science and technology "Optimization of Traction Drive Control". The research of the methods of adhesion control was carried out. Adhesion control performance not only directly related to the traction and braking ability of the train design, but also to the security of the trains running. For example, the failure of iding and slide are caused by adhesion damage. Especially in recent years, our country implementation of the strategy of high speed and over loading, resulting in locomotive traction load increasing, therefore, the research that how to effectively use the adhesive force between wheel and rail, and to achieve optimal control has important theoretical significance and engineering practical value.First, in this thesis, detailed analysis of the mechanical contruction of the locomotive. Using SIMPACK bulid bogies, body and orbit, and establishment of a complete locomotive model to analyze the force, then initialized the system. Through simulation shows the correctness of the model.Second, defined the inputs and outputs of the locomotive model in SIMPACK and built locomotive electric traction drive and motor control model in MATLAB/Simulink. The traction drive and motor control was introduced to the locomotive model, and constructed the co-simulation model that closer to the actual operating conditions of the locomotive. Adopting internationally accepted SIMPACK-MATLAB simuliation tools provide a good simuliton platform for receach of adhesion control, and successfully co-simulation.Finally, after definition of the different rail conditions in platform of co-simulation, according to the basic theory and the existing control method of adhesion control, and used combined correction method and fuzzy control method successfully inhibited the locomotive iding/slipping, improved the operational status. The control methods and the platform of co-simulation feasibility were confirmed.The platform of co-simulation truly reflected the control effect, and laid the foundation for the new control strategy and control algorithm. Compared with the physical prototype, the platform of co-simulation reduces the test cost, shortens the development period and provides an effective research tool for research of optimization adhesion methods.更多还原
