Abstract: Based on the requests of the ground docking simulation test facility, air bearing, fluid bearing and turn table attitude simulating device are analyzed, a bending resistant attitude simulating device is presented from above analysis, it is light, large stiffness and intensity, little friction torque. The bending resistant attitude simulating device are optimized with ANSYS, the whole mass are reduced 23%. Because of special use condi-tions of the bearing, the friction torque of the attitude simulat-ing device are test, data shows that the friction torque of the passive docking simulation test facility is 5.6 N·m, the active’s is 1.32 N·m. It is shown that the bending resistant attitude simulating device is one convenient device which makes the docking on the ground equal to that in space.
