The optimization of the loading ramp mechanism of a heavy-weight trailer

Abstract

This research optimized the loading ramp mechanism of the trailer for transporting heavy construction machiner to minimize the force in the hydro-cylinder. Firstly, a mathematical model for the mechanism transition between the loading and unloading position was established. Then, it was used to optimize the lengths of the mechanism members using the metaheuristic method to achieve the operational function of the ramp. Besides the lengths of the members, the positions of the lever, which transfers the action of the hydro-cylinder to the ramp and the hydro-cylinder, were also considered during the optimization process. Finally, the optimized positions were determined by their coordinates in the vertical plane.
