Abstract


Mine Battery Locomotive of mining production is one of the main means of transport , with the development of mining technology and mining production increases, the locomotive transport capacity requirements are also increasing . However, with the locomotive transport capacity increases, the braking performance has not been a corresponding increase , unable to meet the \Therefore, improving the engine braking performance pneumatic brake system , the brake to ensure the safety of the premise of increasing the transport capacity locomotive has some practical significance. Firstly, the analysis 8t Mine Battery Locomotive Vehicle Specifications and braking systems , based on the braking process through mechanical analysis of the brake wheel , wheel and rail adhesion analysis, quality analysis and traction vehicle stress state analysis, a mathematical model of the braking process . Then use ADAMS / view modeling and simulation techniques were different conditions for locomotive braking process simulation. By comparing the simulation results obtained with the theoretical analysis , locomotive braking curve basically consistent with the theoretical formula . Meanwhile concluded that third gear speed locomotive running full emergency braking distance exceeds safety statutes . Finally, the analysis results combined with the previous output of locomotive brake mechanism inefficient braking force and braking prolonged air travel is causing emergency braking distance overrun the main reason. In order to solve the above problems of the countermeasures to this article , including the following two aspects: ( 1 ) the critical braking mechanism to optimize the design ; ( 2 ) design a motorcycle bent fork intelligent brake control apparatus . Through simulation analysis concluded that these two measures a good solution to emergency braking distance gauge locomotive problems . Through this research , the mining Battery Locomotive pneumatic brake system design and experiments provide an important reference , research results have certain theoretical guidance and practical application significance.
