摘要:
设计了一种应用于有轨电车的永磁减速装置。基于永磁体移位形成不同磁路的基本原理，产生不同的磁场与涡流作用条件，分析永磁减速装置制动性能，建立了结构仿真模型。通过优化永磁体磁极厚度、转盘厚度和永磁体内外半径尺寸等主要结构参数，进行提高制动力矩分析演算。为验证仿真模型的有效性，研制试验样机。将制动转矩仿真值与试验值进行对比，制动转矩误差在5%以内。
Abstracts:
A permanent magnet deceleration device applied to modern tram is designed. Based on the basic working principle of different magnetic circuits, different magnetic fields and eddy current action conditions generated by permanent magnet displacement, the braking performance of the permanent magnet deceleration device is analyzed, and a simulation model is established. Through optimizing the main structural parameters such as the thickness of the permanent magnet poles and the turntable, the inner and outer radius dimensions, an analytic calculus is conducted to improve the braking torque, and a test prototype is developed to verify the effectiveness of the simulation model. Finally, the brake torque simulation value is compared with the test value, it shows that the brake torque error is within 5%.
