Numerical Simulation and Experimental Study on Axial Stiffness and Stress Deformation of the Braided Corrugated Hose

To explore the mechanical properties of braided corrugated hose, space curve parametric equation tube is deduced, specific to structural features tube. On this basis, equivalent model proposed based on same axial stiffness in order improve calculational efficiency. The geometric and Finite Element Model DN25 hose established. numerical simulation results are analyzed, distribution stress frictional discussed. maximum occurs at tube, with value 903MPa. bellows area contact 314MPa. between 88.46MPa. tensile experiment performed. good agreement test data, a error 9.4%, verifying rationality model. study helpful research provides base for wear life studies hose.
