Abstract: Aimed at the situation in lack of analysis tool to evaluate the closing effort of sliding doors in the early design stages, a co-simulation combined with dynamics analysis was proposed based on ADAMS and numerical iterative solution based on Simulink. A rigid-flexible coupled multibody model was built to perform dynamics simulation analysis on the sliding door systems; the differential equation of the changes in air pressure caused by airflow compressed by sliding doors in the closing processes was derived, and the iterative solution process was built in Simulink. The closing efforts of the sliding doors were performed by the co-simulation method with a result of 4.4 J, where the effort costs by air-binding and weather stripping are 48.9% and 36.6% respectively. At last, the accuracy of the co-simulation was verified as the errors of closing efforts from simulation and experiment are below 10%, which prove the co-simulation reliability.
