Research On Analysis And Optimistic Design Of Industrial Hose Pump Using Thorough Cycle Simulation And Meta-model Method

An industrial hose pump uses high performance cord-rubber compo sites reinforced hose to pump multi-phase,abrasive,corrosive,or shear-sensitive fluids.The operating of an industrial hose pump is similar to a squirming animal intestine.This paper aims at designing,analyzing and optimizing an industrial hose pump.Firstly,a finite element model with rebar element is used to represent the cord-rubber reinforced hose.Two practical tests are designed for the counter force and profile deformation characteristics of the hose during compression,and the simulation results show good accuracy.Secondly,with the hose model,the paper conducted a thorough cycle simulation of the hose pump.However,the time spent to conduct hose pump simulation is very long.A series of meta models of the hose pump are used to optimize the designing parameters,so that the stress and strain in the hose can be reduced and the life of the hose can be prolonged.Using meta models can get a fast and precise optimal results,ensuring the speed and accuracy at the same time.Optimal Latin Hypercube Sampling method(OLHS).and Spport Vector Regression method(SVR)are applied to build the meta model.Genetic algorithm is applied to get the optimal design parameters.Finally,the optimal design is verified by testing the physical prototype.In the chapter 1,the development and application of the hose pump,the analyzing method of the cord-rubber material,the modeling method of meta model are introduced.There included the background,the significance of this investigation and the main contents of the paper.In the chapter 2,the modeling methods of the cord-rubber reinforced hose and the meta model of an industrial hose pump is researched.The most suitable methods are chosen.In the chapter 3,the author conducts force analysis and analyzes the potential failure causes.After that,the cord-rubber reinforced hose is modeled and verified by practical tests.Based on the hose finite element model,the thorough cycle simulation is conducted.In the chapter 4,the transmission system is optimized.A novel transmission system design,short coupling transmission sytem,in which part of the pump shell is used as a cantilever,is applied to reduce the load applied on the bearings.The life cycle of the transmission system is prolonged.In the chapter 5,the meta models are built with samples and support vector regression method.With genetic algorithm,the optimal design of the hose and pressing shoe of the hose pump is obtained.According to the test results,the life of the hose pump is prolonged significantly.
