Abstract


Shear’s disc brake is located at the axle end face of electrical shearer, it is used to decelerate or stop the moving apparatus of the shears, and its performance affects the safety and reliability of the shears directly. Currently, there is few testing equipment for shear’s hydraulic disc brake. Therefore, research on the test bench of shear’s hydraulic disc brake has very important engineering value.According to the character of the brake, this paper researches on the test bench of hydraulic disc brake of the coal mining machine. The main research includes several following aspects:The system adopts finite element analytical software ANSYS10.0 to deal with numerical simulation of temperature field in the front structure and the friction coupling of shear’s hydraulic disc brake. This can provide theoretical basis for installation position of temperature sensors and temperature measurement. The system of flywheel is designed by means of deciding inertia load and choosing the simulation mode of inertia. Based on this, the power of driving motor is decided and the mechanical devices such as testing cabinet of the brake, wear detection mechanism and axis are designed. By doing this, the mechanical system of the test bench is finished.After having finished the design of hardware and software in the detecting and controlling system, several functions such as the speed adjustment, data storing, data saving and communication between single-chip microcomputer and PC are carried out. With respect to the hardware, the system adopts single-chip microcomputer 8051F005 as its core control and related circuits are designed. The design of software mainly includes single-chip microcomputer and higher computer. The interactive interface of the detecting and controlling system has been designed by programming in the Virtual instrument Lab windows/CVI.According to GB, torque, rotational speed, temperature and wear have been measured via experiment and the property of brake of the coal mining machine has been verified. So it offers safety, product quality and reliability assurance for the shear’s hydraulic disc brake.
