摘要
电机械制动系统是轨道交通制动领域新的发展方向。驱动电机是电机械制动系统的核心动力源,要求大力矩、小尺寸、高响应速度。现有电机难以满足要求,往往需要特殊研制。分析了电机械制动用驱动电机的原理、结构及驱动方式,基于Ansoft对一套现有的驱动电机参数进行了磁路计算、空载及额定工况有限元仿真,得到了电机性能参数,证明了设计合理性。针对驱动电机的主要堵转工况,提出了两种模拟堵转工况的有限元仿真方法,并对比了优缺点。
Electromechanical braking system is a new development direction in the field of rail transit braking. The drive motor is the core power source of the electromechanical braking system,requiring high torque,small size,and high response speed. Existing motors are difficult to meet the requirements and often require special development. This article analyzes the principle,structure and driving mode of the drive motor for electromechanical braking. Based on ansoft,a set of existing drive motor parameters were calculated by magnetic circuit,no-load and rated working condition finite element simulation,and the motor performance parameters were obtained,which proved the rationality of the design. Aiming at the main locked-rotor conditions of the drive motor,two finite element simulation methods for simulating the locked-rotor conditions are proposed,and the advantages and disadvantages are compared.
