Description

There is a trade-off problem between the distance and the repeatability in golf. Our goal is to obtain the pareto solution by formulating the problem as a multi-objective optimization, and to develop the optimal golf shaft for the player. Club speed and body burden were used as indexes for the distance and the repeatability. Finite element method and multibody dynamics were used for the calculation of the club speed and the body burden. Response surface method was applied to get a pareto solution. As an analytical result, it was found out that the optimized shaft increased club speed by 2.2 m/s and decreased the body burden by around 7% compared to the control shaft. The optimized shaft was manufactured and conducted some experiments for validation. As average data of 10 shots, the distance increased by 8 yds and repeatability was improved by 16 yds with the optimal shaft.
