Improved Genetic Optimization of Electric Motorcycle Planetary Transmission

Abstract:

Determination of dedendum circle diameter of ring gear in planetary gear drives is an important issue in preliminary design of electric motorcycle transmission. Genetic optimization is used to automate preliminary design of gears by minimizing volume of gear trains. An improved genetic optimization method was applied to a planetary gear transmission of electric motorcycle. Gray code way was applied in variable binary strings for improve research efficiency. Dynamic penalty functions were introduced to the objective function for handing the design constraints. The results were compared with a enumeration method usually applied. Improved GA produced quite well results promptly supplying design parameters of a planetary gear transmission.
