Abstract：It is extremely complicated that the stress on articulated body of articulating steering system when steering, the three-dimensional model of articulated body was established utilizing 3D modeling software CATIA and the maxi-mum load in the process of steering was acquired through analysis and calculation on structure and strength of articula-ted system based on FEM simulation. The result indicates that the upper and lower articulated pins bear the larger load of the whole system in the process of steering. The obvious stress concentration exists in local area. The stress of pin that connects with extending cylinder and free bearing is definitely larger than that of which connects with shortening cylinder. In order to validate the analysis results, the vehicle test was carried out. The results of test and theoretical analysis fit well.
