Braking System Research For The Mine Rescue Carrier Robot

The mine rescue carrier robot carrying rescue robot quickly arrives at the location of the coal mine accident after coal mine accidents happened, and then the rescue robot start to carry out rescue work. The main task of this paper contains the structure design, theoretical analysis and simulation study for braking system of the rescue vehicle. In combination with the complex environment of the coal mine after the accidents and the purpose to realize intelligent control of vehicle, the decision is to adopt electromagnet force as the driving force of the braking system.This paper analyze the braking process of the mine rescue carrier robot, and establishes mathematical model of the braking distance and time, and designs the overall structure of the electromagnetic brake according to the working principle of electromagnetic brake;Simulation analysis was carried out on the rescue vehicle braking system using the software ADAMS. This dissertation gets the parameter of curve of braking process and validates the rationality of the design of the electromagnetic brake. The distribution characteristics of time-varying node temperature and the stress of braking disc is obtained by using ABAQUS to simulate transient thermodynamic of the brake. At last, the fuzzy controller of braking system is designed by using the Matlab fuzzy logic toolbox and realizes the independent braking.This paper verifies the feasibility of the electromagnetic brake design of the mine rescue carrier robot through the design and research. The research results guiding significance to the theory and practice, and provides a reference basis for design and research of the new type of braking system of mine rail vehicles.
