摘　　要：介绍了下运带式输送机盘式制动液压系统的组成及原理,建立了电液比例系统的关键元件——电液比例溢流阀的数学模型,并对制动器电控系统进行了设计,根据所建立的模型和设计的电控系统进行了模拟试验,测得了系统在闭环控制下的速度曲线。The paper describes the constitution and working principle of the hydraulic system of the disc braking system of the downward belt converyor,and establishes the mathematical model of the electrohydraulic proportional relief valve that is the key part of the electrohydraulic proportional system.The electric control system for the brake is designed and then the simulation tests are carried out according to the established model and designed electric control system.Finally,the speed curve of the system under closed-loop control is obtained.
