The Structural Optimization of Gearbox Based on Sequential Quadratic Programming Method

Taking the gearbox of medium-sized motor truck for example and According to structural features and design requirements of the gearbox, the mathematical model of optimization which takes the basic design parameters of gearbox as design variable and takes weight loss as the target was established. Optimization tool box of MATLAB and Sequential Quadratic Programming (SQP) method were used to optimize the gearbox and good optimization results were obtained, thus the design efficiency is improved and the production cost of enterprises was reduced.
