| Summary: | In order to improve the safety of underground transportation of mine electric locomotive,the existing hand wheel brake shoe brake device is analyzed. Aiming at the shortage of braking performance,a kind of pneumatic ventilated disc brake device is proposed. Referring to the formula and theory of train traction braking,the braking performance is verified by calculation. At the same time,the braking process is simulated and analyzed by the finite element software Abaqus,the temperature field distribution nephogram and the temperature variation curve of the corresponding node are obtained. Finally,the test is carried out. The results show that the braking device can improve the braking performance of mine electric locomotive effectively,shorten the braking distance,and can meet the requirements of MT/T 1064—2008 technical conditions. It provides the basis for the improvement of the braking device of the mine electric locomotive in the future,and has certain application value. |
