[Abstract]:Aiming at the large combination of the topology form expression of the valve core throttle structure and the fluid-structure coupling response in the design of the multi-way valve, a large degree of freedom analytical problem is proposed. A neural network model for the topology combination of valve core throttle is presented. Based on the experimental results of three-dimensional fluid analysis of the valve, the topology of the throttle is classified as a semicircular groove with U-shaped groove. The parameterized composition of circular orifice and other structures is obtained by orthogonal experiment. The three-dimensional fluid analytical response of multi-way valve under the condition of each parameter combination is obtained, which is used as the training sample of backpropagation neural network. The neural network representation of the topological structure combination of the throttling slot is realized, and the initial weight and threshold of the training process are optimized by the evolutionary neural network. The optimized neural network can accurately predict the three-dimensional fluid analytical response of multi-way valve with non-training sample set. The research results show that the model provides a new way for the expression of topological shape in the design of valve core throttle structure. It has practical significance for digital design of multi-way valve.
