摘要
通过分析下运带式输送机制动工况的特点以及盘式制动器的优点,设计出适合各制动工况要求的新型盘式制动器液压系统。该液压系统具有松闸、保压、正常停车制动、超速制动、紧急制动和系统突然断电制动等功能。建立了系统的数学模型,将数学模型线性化后推导出了系统传递函数,分析了各元件参数对系统响应性的影响,为设计压力精细调节的制动器提供了理论基础。
The characteristics of braking condition of downward belt conveyor and advantages of disc brake were analyzed. A new hydraulic system of disc brake which met each braking condition requirement was designed. This hydraulic system have functions of loose braking, the normal parking braking, emergency braking and suddenly lose power braking. The mathematical model of this hydraulic system was established. The transfer function of this hydraulic system was deduced by the mathematical model linearization. The influences of the parameters to the response of the system were analyzed. The research work lays theory foundation for the design of brake with pressure fine adjustment.
