基于车用电涡流缓速器温度场分析控制系统设计

随着车辆向大型化,高速化的发展趋势,车辆正常行驶制动能量增加,传统的摩擦制动器已经难以满足使用要求,很容易诱发一些故障。电涡流缓速器以其非接触无摩擦,响应时间短,无明显时间滞后,工作时噪声很小,能够提供车辆正常行驶85%的制动功率等优点成为新型的车辆辅助制动系统。本文采用ANSYS软件实现电涡流缓速器转子盘的二维温度场分析,对不同宽度的转筒式电涡流缓速器的温度分布进行数据采集,建立转筒式电涡流缓速器转筒的二维模型,采用虚拟边界法进行简化处理,然后根据系统不同的载荷和约束条件进行温度场控制系统建模。最后本文做了大量的仿真实验,模拟了依据不同的制动力矩,不同的磁路结构以及转子盘温升来分析对汽车制动性的影响。

Design and implementation of vehicle the temperature of an electric eddy current retarder control system

with the vehicle to the large-scale, the development trend of high speed, the normal running of the vehicle braking energy increases, the conventional friction brakes have been difficult to meet the use requirements, it is likely to cause some trouble. Eddy current retarder as non contact without friction, short response time, no time delay, when the noise is very small, can provide the normal running of the vehicle 85% brake power has become a vehicle auxiliary braking system model. This paper uses the ANSYS software implementation of eddy current retarder rotor plate two-dimensional temperature field analysis, establish the rotor disc model, and then temperature modeling field control system based on different loads and constraints. Finally, this paper made a large number of simulation experiments, simulation of the braking torque according to different, different magnetic circuit structure and the rotor disk temperature analysis of automobile brake performance.
