Experimental Verification of Deformation Behavior of Towing Hitch by Optical Measurement Method

摘要

The paper deals with verification of stress-strain results of finite element analysis (FEA) of the towing hitch for passenger's car by experimental measurement. For the purpose of experimental measurement a stand, which allows adjustment and monitoring of loading forces of the towing ball in two axes, has been designed. Monitoring of loading forces was performed by strain gauge force transducers and CatmanEasy software. Static deformations were measured by industrial photogrammetric system Tritop. 3D virtual model of towing hitch for FEA was created by reverse engineering using 3D scanner Atos III Triple Scan. The paper presents results of FEA in comparison with the results of photogrammetric measurements performed on an experimental stand.
