Modeling and Analyzing the Structural Behavior of a Locally Fabricated Timber Truck Trailer Bed in Ghana


A timber truck trailer is a large truck used to carry timber logs. Some of these trailers are locally fabricated in Ghana, mostly at the industrial enclaves. There are basically three types of trailers which are fabricated at the Suame industrial enclave in Kumasi where the study was carried out. These are: square, triangular, and the circular beds. The purpose of this study was to model and analyze the effects of loading conditions on the structural behavior of a locally fabricated timber truck trailer beds in Ghana. The study employed the finite element method for the modeling of the structural reliability of the timber truck trailer beds. Finite element method has three basic features. The results obtained shows a maximum von-Misses stress on the timber truck trailer bed as 285.43 Mpa and maximum yield stress of the material as 250 MPa which is not safe according to Maximum yield stress theory. From the results obtained, it is concluded that the Timber Truck trailer has stresses above the design limits of the material used. Hence, the designed Timber Truck trailer will fail under the given condition.
