Design and Structure Optimization of the Large Winch Drum

The drum is the key part of the winch. The mechanical model of drum was established in this paper, according to the actual working condition of the winch to determine the load form and the stress analysis was carried out. The calculation results were analyzed, and the drum structure was further optimized to improve. The paper provides a reference method for design of large winch drum to meet the working performance and the quality of the drum was effectively reduced.
