摘　　要：由于轮胎与路面附着的非线性特性,有轨电车在制动过程中容易发生车轮打滑或抱死现象,从而导致严重的车轮磨损和爆胎事故。为保证有轨电车的制动性能和行车安全,提出了一种基于高速开关阀的压力闭环控制与滑移比闭环控制的有轨电车液压制动系统防滑控制策略,可独立控制每个车轮液压制动力以防止车轮在制动时出现滑行现象。经线上防滑试验,结果表明本策略可达到预期的功能,保证了车辆的制动效率及制动过程的安全性。Due to the nonlinear characteristics of tire adhesion to the road surface,the tram is prone to wheel slip or lock during braking,which leads to serious wheel wear and tire blowout accidents.In order to ensure the braking performance and driving safety of tram,a new anti-skid control strategy of tram hydraulic braking system based on pressure closed-loop control and slip ratio closedloop control of high-speed on-off valve is proposed in this paper.Through the anti-skid on the test line,the results shows this strategy can achieve the expected function and ensure the braking efficiency of the vehicle and the safety of the braking process.
