Modeling and Validation of Large Hydraulic Hose Deflections

A modeling methodology is being developed to aid in routing and predicting movement of brake hoses with the objective of having an adequate representation in a Computer Aided Design (CAD) system for virtual prototyping. Once mount points and orientations have been specified,material properties and length determine the path of the hose.

Data, collected on a straight and deflected hose at several points along the length of the hose, were compared to an ADAMS simulation. Problems that were encountered in metrology and data transfer are discussed along with their potential impact on the modeling accuracy.
