To ensure the stability and reliability of the rotational chain shell magazine moving system, the trajectory planning such as cubic curve, quintic curve, T-shaped velocity curve and S-shaped velocity curve were considered in this paper. The effectiveness and feasibility of each trajectory planning method for the control system of the rotational chain shell magazine were verified by the combination simulation technology of MSC. ADAMS and MATLAB. The simulation results show that the S-shaped velocity curve satisfies the requirement of the smoothness and continuity of the trajectory of the magazine. It ensures the continuity of angular velocity and acceleration, and reduces the buffeting and impact effectively that other curves can’t satisfy. It is of great significance for the stability and reliability of the rotational chain shell magazine.
