using rubber pad forming process for local compression in assembling of vehicle structure tubes

nowadays, tube bonding in vehicles structure is noticeably considered by many researches. in this paper, local tube compression process by a rubber ring has been studied. firstly, simulation of the process was performed by fem. then, experimental test has been carried out to validate the numerical results. numerical and experimental results were compared showing a good agreement. in the second part of this study, tube assembling of a two tubes was examined by a rubber ring. the simulation results have presented including stress distribution of both tubes. finally, this method was compared with other tube assembling methods by observation of tube profile deformation.
