Static Analysis of Trailers with Demountable Chassis

Today, trailers are the most used vehicles in intercity and international road transport. There are serious difficulties in the production processes and post-production shipments of these vehicles. Trailer chassis are generally produced in welded structures. In this study, the trailer chassis produced in welded structure was transformed into a bolted structure. A nonlinear finite element model was created and static analyzes of the demountable chassis trailer have been made. In these analyzes, stress and deformation data on the chassis part of the trailer were observed. It is concluded that the deformation of the chassis under these loads is at an acceptable level. As a result, it has been shown that welded structures in trailer chassis can be transformed into bolted structures and there is no problem in terms of safety.
