To overcome the drawbacks of the traditional ramming mechanism, such as complicated maintenance and low reliability, an artillery ramming mechanism is proposed in this study based on the principle of a double primary tubular permanent magnet synchronous linear motor (TPMSLM). First, a subdomain model is proposed for this mechanism, which significantly simplifies the programming difficulty by solving through coordinate transformation. In comparison to the finite element method (FEM), the analytical method considers the flux barrier and end effects, resulting in high calculation accuracy. Then, considering the uncertain factors in the machining process, an interval uncertainty optimization model considering robustness is established using the interval order and interval probability degree method, which is further solved via interval nesting optimization. Compared with the initial structure, the average thrust and thrust density of the optimized structure are increased by 32.7% and 12.4%, respectively, with almost constant thrust ripple. Finally, a prototype and control platform are developed to verify the validity of our work and superiority of the proposed structure through experiments involving electromagnetic parameters and comparative experiments.
