The lifting-and-lowering type drone station is very useful when lifting and lowering the battery charging station for safe installation, maintenance, and energy efficiency of drone operation. Therefore, understanding the coupling motion between cable and pulley is important for evaluating characteristics like safety and dynamic stability of the lifting-and-lowering type drone station. Although multibody dynamics (MBD) is widely used for numerically analyzing the dynamic behavior of interconnected bodies, attempts to analyze the coupling motion between cable and pulley have been made only recently, within the last decade. Therefore, this paper attempts to develop the MBD model for the lifting-and-lowering type drone station, including cables, pulleys, and winches using MotionSolve (Altair). The results of the winch torque obtained analytically and numerically were compared to verify the effectiveness of the proposed MBD model.
