Abstract

The invention discloses a vibration screen optimization design method using Gaussian harmony searching. According to the method, a Gaussian tone regulating strategy is designed in a harmony searching algorithm; searching information of outstanding individuals and random individuals in a harmony library is used; a Gaussian random number generation function is combined to generate new individuals; and the convergence speed is possibly accelerated while the diversity of the harmony library is maintained. In addition, a differential mutation strategy is used for performing local searching; the local searching capability of the algorithm is enhanced; the convergence speed of the vibration screen optimization design is accelerated; and an optimum individual obtained in the calculation process is the result of the vibration screen optimization design. Compared with a similar method, the method provided by the invention has the advantages that the convergence speed of the vibration screen optimization design can be accelerated; and the precision of the vibration screen optimization design can be improved.

Description

technical field [0001] The invention relates to the field of vibration screen optimization design, in particular to a vibration screen optimization design method using Gaussian harmonic search. Background technique [0002] Vibrating screen is a common mechanical equipment in industrial processing and manufacturing, and it has a very wide range of applications in industrial production. The general process of the optimal design of the vibrating screen is to first establish the optimization objective function according to the physical and mechanical characteristics of the vibrating screen to be optimized, and then determine the variables required for the optimal design, and determine the constraints that the optimal design of the vibrating screen needs to meet. Generally, whether the optimal design result of the vibrating screen is reasonable or not often affects the final screening effect of the vibrating screen. Therefore, the optimal design method of the vibrating screen i...
