Nonlinear dynamic characteristics and control of planar linear array deployable structures consisting of scissor-like elements with revolute clearance joint

Abstract: This paper comprehensively deals with the parametric effects of the joint clearance and friction coefficient on the dynamics of planar deployable structures consisting of scissor-like elements (SLEs). The dynamic model for scissor deployable structure is based on a comprehensive consideration of the symmetry and array characteristics of this mechanism and on a Lagrange method, which represents the motion equations. A modified nonlinear contact-force model is employed to evaluate the intrajoint contact force, a… Show more

“…Bai et al [14] studied the dynamic modeling and analysis process of space satellite antenna system with clearance, and pointed out that the influence of axial clearance on satellite antenna system cannot be ignored. Li et al [15] studied the dynamic characteristics of the scissor deployable structure in the process of deployment motion using the Lagrangian method. At the same time, the geometric constraint method was used to control the contact collision phenomenon within the joint to ensure the deployment accuracy and improve the deployment stability.…”
