THE DESIGN AND ANALYSIS OF ELECTRIC VEHICLE GEARBOX CASING

摘要

This study includes Design analysis on the use of the Finite Elements Analysis method for two speed electric busses gear boxes. When designing the gearbox, the strength of the transmission system is very important. Using NX software, the 3D model is developed, and FEM is resolved with Ansys 14.5. Using statisticalanalysis, it is detected the total stress amount and displacement of the gearbox case. Dynamic analysis is used to find out the natural frequency of the gearbox casing. This process helps to determine how the gearbox case is optimized, in which it performs best without failure and has minimum loads on the case.In designing a gearbox housing, FEA should also be carried out to determine whether or not the design is safe.
