Modeling and simulation of the stiffness of deployable structures based on scissor-style unit

The stiffness of deployable structures based on scissor-style unit is often insufficient. The stiffness can be improved by changing the element if the stiffness model of deployable structures based on scissor-style unit is modeled. Firstly the force of single scissor-style unit needed to be analyzed in order to get the force model of every joint in each unit. Then the stiffness model of deployable structures can be established by analyzing and calculating the deformation of the links in each unit based on the force model. Finally simulation analysis should be done to verify the reliability of the established stiffness model by setting specific parameters and using simulation software to establish the three-dimensional model.
