摘　　要：为防止下运带式输送机在制动过程中由于加速度突变对带式输送机机械系统产生过大冲击,将余弦加速度运动规律,应用于盘式制动器制动过程,采用PWM技术对制动控制系统进行分析与设计。To avoid large impact of sudden change of accelerated speed to the belt conveyor system during braking of the downward belt conveyor, the cosine acceleration law is applied to the braking process of the disc brake. The brake control system is analyzed and designed by adopting PWM technology.
