Abstract:In order to study motion characteristics of rotating hinges with clearance in motion process of a space mechanism under different gravity environments, the motion behavior of the mass center of a rotating hinge with clearance under different gravity environments was studied taking a crank-rocker mechanism with clearance as the studying object.Firstly, a continuous contact equivalent model was used to establish the model for the crank-rocker mechanism with clearance under the ground and space microgravity environments.Then, this model was re-built with the software of ADAMS, and simulation tests for the crank-rocker mechanism were performed, respectively with different clearances and crank rotating speeds under different gravity environments to complete the mass center’s motion characteristics analysis of a rotating hinge with clearance. The simulation results showed that the motion behavior of a rotating hinge with clearance’s mass center basically is not affected by crank rotating speed under the gravity of 0; the motion range of a rotating hinge with clearance’s mass center increases with increase in crank rotating speed under the gravity of 1g; the larger the clearance, the more easily the motion behavior of a rotating hinge with clearance’s mass center mutates.
