Optimization Analysis of Ship Windlass Drum Based on RSM

This paper focuses on the optimization analysis of the winch drum in a ship anchoring machine using the Response Surface Method (RSM). A detailed analysis of its working principle and force conditions is conducted. Based on this, a high-accuracy finite element model is established in ANSYS Workbench. RSM is then applied to construct objective and surrogate models, enabling the exploration of the relationship between design variables and performance metrics. Through optimization, the stress distribution is significantly improved, the maximum equivalent stress is reduced, and material utilization is enhanced. These improvements contribute to the structural reliability and efficiency of the anchoring system, offering valuable guidance for engineering applications.
