Kinematics analysis and driving design of multi-module deployable structure

Kinematics analysis and driver design of multi-module deployable structure Due to the deployment need of deployable structure in space missions, kinematics analysis and driver design of the structure were important. Based on the studied space multi-module deployable structure with the periodicity characteristics of single module in circumference direction and incompletely periodicity of the multi-module linkage, kinematics modeling of single module was conducted by using plural and decomposed method. At the same time, the kinematics model of multi-module deployable structure was established, which satisfies the aimed surface fitting. Then kinematics analysis of multi-module deployable structure was achieved to get the relationship curve between the location of the moving parts and the deflection of the modules. It was found that the deflections of the modules increase with the displacement of slider and reach 1.22 degrees. Based on the kinematics analysis of structure, the force curves of the sliders and the joints under different driver styles during deploying are given. The diver analysis and driver design with low mass and high reliability for deployable structure which can guarantee the smoothly deploying.
