Power steering hose is device that operation oil passes between steering gear box and oil pump by parts that is used to do steering system. Because this hose is receiving heat and pressure of high temperature, leakage can produce swaging from hitch of steel materials of done part. In this paper, we analyze swaging process of power steering hose by finite element analysis, and achieved thermal and pressure analysis with this shape. We can analogize weakness part of hose through this result, and examine closely oil leakage and rubber failure mechanism and look for important design benevolence of power steering hose development.

Swaged power steering hose is receives mechanical load and heat from oil pump and enging in the engine room. In this paper, we perform the numerical analysis to evaluate the contact force, spring back and plastic deformation of power steering hose. For the sake of accuracy of analysis, we regard to nonlinearities such as material and geomerical nonlinerities and nonlinear contact of boundary condition. In order to investigate effectively mechanical behavior of power steering hose we use the finite element method

The power steering hose is used to connect the hydraulic pump to power steering gear. This hose experience very high temperature and pressure due to the oil flowing inside. Because of this reason, the hose may be broken of oil may leak from the hose. Therefore it is important to predict the behavior of the power steering hose accurately. For th available analysis of this problem, we model the power steering hose using finite element method effectively. Also, we study on the FE formulations for rubber-like materials and the nonlinear analysis schemes for large deformation problems.
