초록

The purpose of this study is to optimize the plate thickness of the main frame of a construction equipment. For this, the load history at the joints of the main frame was evaluated using mechanism and finite element analysis. With the load data, the stress and the stiffness at the main frame was evaluated and the fatigue life at each weld joint of the main frame was assessed with the change of the plate thickness. Based on the results of this study, the proper plate thicknesses of the frame of the construction equipment were proposed.
