Abstract
Hydraulic hose is being used to transmit the hydraulic pressure in various industrial fields such as construction machinery, automotive, etc. However, since the hydraulic hose is hard to be designed using CAD software and assembled finally after all other components except the hydraulic hose are assembled completely, the problems like interference occur when assembling. To solve this problem, the use of commercial software that predicts the path of the hydraulic hose has been suggested in the design process. To generate the path of the hydraulic hose using commercial software, the material properties such as material bending stiffness, tensile stiffness, torsional stiffness, etc. are required. However, there is an error between the path of hydraulic hose generated by the commercial software by applying the material properties and the actual path of hydraulic hose. Therefore, in this study, to find the virtual material property close to the actual path of hydraulic hose, the backward tracing scheme was performed. To verify the accuracy of the backward tracing scheme, each path of the hydraulic hose was generated by applying the values of the material properties measured using material tests and the values of the virtual material properties obtained through the backward tracing scheme, and the validity and the accuracy of the backward tracing scheme were verified by comparing the path and the centerline of hydraulic hose after acquiring the coordinates of the centerline of the hydraulic hose connected to jig with 3D scanner.
