Analysis Of Equivalent Pulling Mechanism Of Tension Based On Similar Suspension Principle

Aiming at the requirement of zero gravity unloading efficiency of space mechanism in ground test stage, the design of equivalent tension mechanism based on similar suspension principle is proposed. By designing the suspension element, the tension is applied to the finite structural points on the spatial mechanism and applied to the actual center of mass of the spatial mechanism, thus counteracting the influence of gravity. In this paper, the structure of suspension element with equivalent tension is introduced in detail. The key components are analyzed by finite element method. The results show that the structure design meets the requirements.
