Nonlinear dynamic analysis of deployment of laminated planetary rover mast

摘要

In order to study the exact dynamic behavior of flexible laminated appendages undergoing a large rotational deploying motion, the nonlinear dynamic model for laminated planetary rover mast(LPRM) is established taking into account the constitutive relations of laminated composite materials using Hamilton variational principle. Numerical simulations are carried out on the basis of laminated structure and single layer structure of material. The analysis shows that the structure of laminated composite material has a significant influence on the system dynamics. The results of this paper have important theoretical value and engineering significance for imaging quality of optical equipment and working accuracy of navigation equipment.
