- Abstract
- For hydraulic equipped machines the routing design of hydraulic hoses is one of significant factors in preventing interferences and improving kinematic functions between mechanical parts.
High pressure hydraulic hoses are in general made of composite materials such as rubber and wire braid for reinforcement. Therefore material properties of the hoses have non-linear behavior and make difficult to compute routing using analytical methods. This study proposes a method for computing virtual material properties by back tracking on actual paths of hydraulic hoses. For this we first extract the centerline of a hose from actual path using a 3D scanner.
Then the virtual material property is estimated through optimization to minimize the distances between centerlines of the actual path and of a set of simulated paths computed with analytical software. We provide the discussion to prove the effectiveness of the back tracking method by comparing the computed paths and actual paths generated with many different types of SAE standard hoses.
