Aiming at the problem of mechanical property test for articulated device, the structural principle of articulated devices of rotation, fixed and free was briefly analyzed, and three kinds of new component test schemes, i.e. rotation "vertical + yaw", fixed hinge "vertical + torsional" and free hinged device as a whole, were designed and compared with the traditional ones. With the component test program, the fatigue and ultimate performance of the hinge device was studied. The results showed that the design of the three new articulated devices test scheme was reasonable, and the test conditions were consistent with the vehicle operation conditions. The component test could accurately reflect the mechanical properties, fatigue and ultimate performance of the articulated device which could fulfill the requirements. The test results were basically consistent with the analysis results.
