A class of radial retractable roof system that is based on bar structures is introduced. The structural components, deployable mechanism, and its motion features are analyzed. Based on the theory of multi body dynamic method, we apply a co-simulation method of ADAMS and ANSYS to simulate the motion of the radial retractable roof structure. We also examine the impacts of parameters such as the stiffness of the fixed roof, wheel-track friction coefficient, wheel-track clearance, and the roof velocity on the roof’s moving process. The impacts were measured by indicators such as the deflection, driving force, and bending moment of links. It is found that the stiffness of fixed roof had a great influence on the roof deflection under the closed state, while minimal effect under the expansion state. With the increase of friction coefficient and decrease of wheel-track clearance, the driving force increased. The dynamic phenomena of structural behavior are universal existence. The fluctuating range of response curves appeared positive correlation with the friction coefficient and the wheel-track clearance. The conclusions could be provided for the design of deployable roof structure in future.
