Abstract

The invention relates to an intelligent optimization method for fans used in auxiliary converter cabinets, comprising the steps of: S1, establishing an initial geometric and physical model of the original fan and the cabinet body of the converter cabinet; S2, selecting an optimization scheme according to the initial geometric and physical model; S3 , according to the selected optimization scheme, perform parametric modeling; S4, conduct orthogonal experiments on the parameters in the modeling; S5, establish a comprehensive evaluation model of fan vibration and noise performance; S6, construct a neural network, analyze parameters and vibration and noise The corresponding relationship of performance; S7, introduce particle swarm intelligence algorithm, determine the optimal optimization scheme in the neural network; S8, conduct simulation verification on the optimal optimization scheme. The present invention can not only obtain the optimal optimization scheme of auxiliary converter cabinet fan, reduce the aerodynamic noise of cooling fan to the greatest extent, but also analyze the internal relationship between various geometric parameters, flow field, sound field and even product performance in various optimization schemes , which is conducive to the initial design of products and other forms of technological transformation.

Description

technical field [0001] The invention belongs to the field of fans, and in particular relates to an intelligent optimization method for fans used in auxiliary converter cabinets. Background technique [0002] In the field of rail transit, the noise index is not only related to the stability and reliability of locomotives, but also closely related to the comfort of passengers. The centrifugal fan is a high-speed rotating part inside the auxiliary converter cabinet. During the operation of the cabinet, obvious noise phenomena can often be observed. As the main noise source, the aerodynamic noise of the fan duct has always been a key research direction for noise reduction technology. [0003] The traditional optimization and improvement method usually puts forward several reasonable optimization schemes through engineering practice and field experience, and then verifies them by means of simulation or experiment. This method of taking point experiments neither obtains the corre...
