摘要/Abstract

摘要： 履带车辆要求其辅助制动系统响应快、全速段功率密度高，而现有的液力辅助制动技术难以满足需求。为解决这一问题，基于电涡流和液力缓速技术优点与缺点互补的特性，对电涡流缓速器和液力缓速器进行了集成设计，提出一种电涡流-液力复合型缓速器结构。对此结构应用数值模拟方法预测电涡流制动与液力制动的速度特性，研究该缓速器控制策略，得到最佳制动性能。结果表明，电涡流-液力复合型缓速器电涡流部分响应时间在0.2 s以内、转速600 r/min以内主要依靠电涡流制动，转速600 r/min以上依靠电涡流与液力制动共同作用，在转速1 000 r/min工况下能够提供280 kW制动功率。

Abstract: The fast response and high power density for all-speed of auxiliary braking system are required for tracked vehicle, but the existing hydrodynamic retarder can hardly meet the demand. An eddy current-hydrodynamic hybrid retarder (EHR) is presented based on the complementary characteristics of eddy current and hydrodynamic retarter. The speed characteristic of EHR is predicted through numerical simulation. The best braking characteristics were obtained by developing the control strategy of EHR. The result shows that EHR can respond within 0.2 s, depending on the eddy current brake. It mainly relies on the eddy current brake at the rotating speed of less than 600 rpm, and depends on its eddy current and hydrodynamic braking performance at the other rotating speeds. HER may provide 280 kW braking power at 1 000 rpm. Key
