Abstract: Aiming at the problem that the optimization of the mechanical structure for electric sofa, the performance for the function realization of the electric sofa was analysed based on the ADAMS, and the mathematical model that is the link motion of electric sofa was established. The correctness of the mechanism motion was verified in ADAMS simulation by solving the theoretical value of the model. The optimized analysis was carried out that used the Matlab algorithm for the large change range of velocity and angular velocity that effect the stationarity, when the electric sofa change the position from sitting position to lying position. The results indicate that it improves the stationarity in the process of the footrest’s motion using the Matlab toolbox to optimize solution for the objective function, and it improves the comfort of the electric sofa. Finally, it is determined the part important link size of the electric sofa.
