Abstract

The invention relates to a gear reducer optimization method based on an FOA (FruitFly Optimization Algorithm). The method comprises the steps of taking a two-stage gear reducer as a design research object, and establishing a mathematic model with a minimum volume of the two-stage gear reducer as an optimization target; introducing a correction factor described in the specification into the FOA in combination with the FOA to obtain a corrective FOA; and then optimizing the mathematic model established in step S1. The gear reducer optimization method based on the FOA has the advantages of rapid convergence speed and effective avoidance of a local optimum problem on the premise of guaranteeing safety and reliability.

Description

technical field [0001] The invention relates to a gear reducer optimization method based on FOA algorithm. Background technique [0002] The gear reducer is a widely used independent transmission component. How to improve the service life and load capacity of the reducer, reduce the weight and volume of the reducer, and reduce the design cost is of great significance [1] . At present, the traditional reducer design is completed through standardized design, but it has the disadvantage of non-optimized design parameters. Therefore, the optimal design of the gear reducer is realized through the optimization design method. On the premise of ensuring safety and reliability , the optimal design can be quickly realized. [0003] Aiming at the optimal design model of the reducer, combined with the advantages of the fast convergence of the fruit fly optimization algorithm, the correction factor β is introduced into the FOA, and an optimal design method of the modified FOA gear redu...
