A class of radial retractable roof system based on bar structures was introduced. The structural components,deployable mechanism,and its motion features were analyzed. Based on the theory of multi body dynamics,a co-simulation method of ADAMS and ANSYS to simulate the motion of the radial retractable roof structure was presented. The impacts of parameters such as the stiffness of fixed roof,wheel-track friction coefficient,wheel-track clearance,and the roof velocity on the roof's moving process were examined. 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 has 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 increases. The dynamic behaviors of the deployable roof structure are universally existing. The fluctuating range of response curves is of positive correlation with the friction coefficient and the wheel-track clearance. The conclusions could be referential to the design of deployable roof structure in future.
