This study analyses the electromechanical performance of the crawler of a mobile crushing station. Dynamics and electromechanical coupling models of the crawler in horizontal straight and steering conditions are established. Meanwhile, a 1200-t mobile crushing station, which is a virtual prototype, is established based on RecurDyn. Results of electromechanical parameter changes during the operation are obtained through theoretical calculation and simulation analysis of the dynamic performance of the mobile crushing station. Results provide references and basis for the theoretical analysis of electromechanical and ground running performance and design and development of large mobile equipment.
