군용 발사대 고각 구동 시스템의 다물체 동역학 모델링 및 민감도 분석

초록

The military launcher system operates within weight and power consumption constraints, necessitating efficient drive component design and energy usage. However, prototype fabrication and repeated experiments to reflect design changes are inefficient in terms of time and cost, necessitating the development of an analysis model capable of representing actual system behavior. This study used ANSYS Motion to develop a multibody dynamics (MBD) model of a launcher’s elevation drive mechanism. The model incorporated reducer-based power transmission characteristics and an experimentally calibrated equivalent loss torque. The simulation results were compared to experimental measurements to determine model reliability. The results showed that the angular displacement of the POD was accurately reproduced, and the required motor torque exhibited trends generally consistent with the experimental results. In addition, sensitivity analysis using a two-level full factorial design was used to evaluate the effects of major design variables on the required motor torque. The results provide useful reference data for the preliminary design of launcher elevation drive units and similar reducer-based drive systems.
