Simulation and analysis of passenger car sunroof motion mechanism

This paper presents firstly the structure and working principle of car sunroof. Then the reverse engineering and software CATIA were used to build the 3D model of motion mechanism of a car sunroof. Finally the 3D model was imported into software ADAMS to build the virtual Prototype. By applying with the software ADAMS the kinematic and dynamic character of sunroof motion mechanism components during sunroof opening and closing was calculated and studied. The calculated results can be used as the input datum for the design of others components of car sunroof, for example in the design of the power and speed of motor, the size and dimensions of soft shaft. The study in this paper can improve the design quality and efficiency of new sunroof product and it can also remarkably shorten the new product development period and cost.
