[Abstract]:Industrial hose pump is a kind of volumetric pump, which uses high performance cord reinforced composite rubber tube to simulate the peristalsis of biological intestinal tract to transport gas, liquid and solid three phase medium.In order to analyze, design and optimize the industrial hose pump, this paper first realizes the full-cycle simulation oriented rubber limb-cord hose modeling and analysis based on reinforced reinforcement model, and the design test verifies its accuracy.Secondly, the full cycle simulation of hose pump is realized on the basis of hose model.Based on the above analysis model, the optimal Latin hypercube sampling method is used to calculate the sample, and the support vector regression machine is used to regression the result of the sample calculation, and the agent model is established.The genetic algorithm is used to calculate the key design parameters on the agent model and the optimal design scheme of the hose pump is obtained.The test results of the prototype of the hose pump show that the optimal design of the hose pump based on the agent model has achieved good results.The main contents of this paper are as follows: (1) the modeling method of hose for full-cycle simulation of composite pump and the optimization design method based on support vector regression machine agent model are studied.In this paper, the basic technical route of the research is determined. (2) the force of the hose pump is analyzed, and the causes of failure and the failure factors of the prematurely failure hose pump are analyzed and classified.The finite element model of rubber-cord composite hose is constructed, and the accuracy is verified by design and test.Then, according to the actual working conditions and force analysis, the full cycle simulation calculation of the hose pump is designed and realized. (3) based on the full cycle simulation, the drive system of the hose pump is optimized.A "cantilever arrangement scheme for pump shell" is proposed, which distributes radial force, reduces the force on the main rotating shaft and bearing, and improves the life of the pump. On the basis of the full cycle simulation, the optimum design objective and constraint conditions of the hose pump are first determined.Support vector regression machine is used for regression fitting.A proxy model is established.Finally, the key design parameters of hose and slipper are optimized by genetic algorithm.The prototype has passed the test and the life of the prototype has been greatly extended.
