Abstract

Abstract: 2AMT (two-speed mechanical automatic transmission) is widely studied because it can further improve the power and economy of electric vehicles. 2AMT designing process involves repeated assessments and optimizations to meet the requirements of light-weight, strength, and noise control. The force on the gear, gear shaft, and shell is analyzed when the 2AMT motor is running with maximum torque output. Based on the finite element analysis theory, ANSYS software is used to analyze the strength and modal of the shell, and the analysis results are used to optimize the 2AMT structure. Results show that the 2AMT shell meets the strength requirements, and the optimized structure reduces the maximum deformation by 0.057 mm and the maximum stress by 20 MPa, and its natural frequency can avoid the gear meshing impact frequency in the common speed range.

Key words: 2AMT, strength analysis, modal analysis, ANSYS
