摘　　要：电力液压设备制动器间隙会导致制动器在运行过程中存在大量的电能输出与电阻制动损耗,为确保设备的长期稳定运行,提出节能控制环境下电力液压设备制动器间隙自动补偿方法。首先,对电力液压设备制动器运行过程中的能量转化流程与原理进行分析;然后,结合麦克斯韦电磁原理,在原有制动器结构中通过磁吸线圈的部署,实现了制动器的磁化处理,完成电力液压设备制动器的低能耗改良;最后,通过PID控制算法将制动器构件的受力调整问题,转化为电机的转速调节问题,并通过对电机转速的控制,实现制动盘与制动片的快速接触,达到制动间隙的补偿目的。实验表明,所提方法能够在低能耗条件下,实现电力液压制动器的快速间隙补偿,提高了制动器的整体制动性能,具有广泛的实用性和应用前景。The brake clearance of electric hydraulic equipment can lead to a large amount of electrical energy output and resistance braking loss during the operation of the brake.To ensure the long-term stable operation of the equipment,an automatic compensation method for the brake clearance of electric hydraulic equipment in an energy-saving control environment is proposed.Firstly,analyze the energy conversion process and principle during the operation of electric hydraulic equipment brakes.Then,combined with Maxwell's electromagnetic principle,the magnetization treatment of the brake was achieved through the deployment of magnetic suction coils in the original brake structure,completing the low-energy consumption improvement of the electric hydraulic equipment brake.Finally,the force adjustment problem of the brake components is transformed into the speed adjustment problem of the motor through the PID control algorithm.By controlling the motor speed,the fast contact between the brake disc and the brake pad is achieved,achieving the purpose of compensating for the brake clearance.The experiment shows that the proposed method can achieve fast clearance compensation of electric hydraulic brakes under low energy consumption conditions,improve the overall braking performance of the brake,and has broad practicality and application prospects.
