[Abstract]:The gearbox of high-speed train is the key component of bogie, which is composed of carrying and transmitting traction and braking force. Its reliability directly affects the safety of train and the safety of passenger's life and property. At present. The technical parameters of gearbox and the structural size of the top layer indexes of the four platforms EMU in China are quite different. The gearbox has complicated structure and bad operating environment. There have been some faults such as box crack, bearing failure, lubricating oil emulsification and oil leakage during the long service. Based on the above background. This paper mainly studies the structure design and strength simulation of the new type gear box box of the Chinese standard EMU, and carries on the test bench test and the circuit test to the new type box body. The main contents are as follows: 1) combing the fault causes of the existing high-speed EMU gearbox box. Based on the fracture metallographic analysis, strength modal simulation analysis and line dynamic stress test, the gearbox structure is designed from the gearbox structure. The structural design, strength and modal simulation analysis of the new type of gearbox box are carried out according to the requirements of high-speed train gearbox system. The optimal design of the box structure is carried out by using CATIA software. The interface between the box and the frame, the axle, the coupling joint, the installation seat of the suspender of the gear box, the oil level window and the observation hole are studied. The Hyper Mesh software is used to optimize the gearbox hanger mounting seat and oil level window. The static strength and fatigue strength of the box are simulated by ANSYS finite element method to ensure the structural strength of the box is safe and reliable, and the modal simulation analysis is carried out. In order to master its inherent vibration characteristics, the static strength and modal test of the new type gearbox test bench are studied. The short-circuit torque of the new type gearbox box is tested on the test bench, and the stress of the key parts is tested. The strength of the gearbox box is verified, and the modal frequency of the box and the gearbox composition in the free state is tested. Based on the finite element analysis and the test results of the test bench, a new type of dynamic stress and acceleration test scheme was developed. Through line testing, the time-domain and frequency-domain characteristics of the test data are analyzed to evaluate the service life of the box. The above research work is composed of the development of a new type gearbox of high-speed train with independent intellectual property rights. It is of great significance to realize autonomous production.
