[Abstract]:The transmission is one of the main sources of vibration and noise besides the engine and exhaust system among the factors affecting the vibration and noise of the whole vehicle, and screeching is the most common form of vibration and noise of the transmission. Gear manufacturing error excitation has great influence on screeching. By improving gear machining method and increasing gear machining accuracy, vibration and noise of transmission can be reduced to a great extent, but manufacturing cost must be increased. Therefore, under certain technological conditions, It is of practical engineering significance to reduce the vibration and noise of transmission by controlling the main single error without changing the structural parameters of gear. Based on the research of mechanism of vibration and noise of transmission system, The dynamic analysis model of gear coupling vibration considering the dynamic performance of transmission shell is established, and the effects of gear pair coincidence, gear transmission error, meshing misalignment and tooth contact spot on the vibration and noise of transmission system are analyzed. The causes are explained in theory. The finite element modal analysis and experimental verification of the transmission shell are carried out. The effectiveness of the shell analysis model is discussed in terms of the modal frequency error and the MAC value of the mode mode correlation. Based on the MASTA software, the simulation analysis model of the transmission system considering the elastic deformation of the shell is established, and the flexible shell is analyzed. The effect of the body on the dynamic meshing characteristics of the gear pair. The results show that the elastic deformation of the transmission shell affects the meshing misalignment of the gear pair. The contact spot of gear surface and the peak value of transmission error of gear pair have obvious deterioration effect, and the peak value of dynamic meshing force of gear pair has strong correlation with the mode of transmission shell. The distribution of contact spots on the tooth surface is obtained, the validity of the simulation analysis model of the speeder system is preliminarily verified, the vibration and noise experiment of the transmission single unit is carried out, and the influence of the speed, load, and the comprehensive error of the gear on the whistling of the transmission is obtained. At the same time, the validity of the analysis model is further verified. Combined with the simulation analysis and the experimental test results, the structure of the transmission shell is optimized. Based on the simulation analysis model of transmission system with synthetic manufacturing error after experimental correction, the gear synthesis error is modified into a single error, and the base node deviation is studied respectively. The influence of helical deviation and radial runout deviation on the gearbox's whistling performance is studied.
