Research on Weight Optimization of Multi-Stage Cylindrical Gear Drive and Effect of Objective Function Form on Optimization Results
School of Mechanical Engineering, Northwestern Polytechnical University, Xi'an 710072, China
The minimal weight design problem of multi-stage gear drive is always the key issue in engineering research. Generally, the weight of gear drive system is mainly made up by the weight of gears, shafts and gearbox. While, the weight of these three parts are mainly determined by the basic parameters and layout parameters of gears and shafts. Thus, a new optimization model for the optimization of basic parameters and layout parameters of cylindrical gear drives was proposed. To verify the applicability, the present model is applied to the weight optimization problem of a ZSY three-stage cylindrical gear reducer and solved by genetic algorithm. Meanwhile, three different formats of objective functions that can realize the object of weight optimization are applied to the optimization problem individually. Comparing their optimal results, the best fitting format of objective function has been found.
