A current in production 6000 lb. rated boat-lift is being sold at “Great Lake Lifts”. The lift was tested experimentally and proved to hold at least 8000 lb. The design team successfully modeled the current lift on Ansys to help the customer understand where the weakest points in the design were. Following the creation of the initial lift design, the design team proposed and tested modifications that could be made in order to make the lift more structurally sound. The initial lift had a maximum deflection of 0.43846 inches, a maximum stress of 15880 psi, and a safety factor of 2.5216. The final recommendations from the design team decreased the maximum deflection to 0.24904 inches, a maximum stress of 5490.2 psi, and a safety factor of 7.2912. The recommendations were all built using SOLIDWORKS and tested using Ansys with a few recommendations showing that relatively small modifications can result in significant changes.
