    • case studyGolf Club OptimizationMaximising Club Performance & AestheticsTo ensure consistency throughout the world, golf’s ruling bodies have determined rules which set a uniformstandard for the “spring-like” effect in driving clubs. What this means for equipment manufacturers is that they mustdevelop their products to meet the appropriate standards while maximizing performance and be pleasing in theeyes of the consumers. The United States Golf Association (USGA) Rules of Golf state that clubs must conformto guidelines including the “coefficient of restitution” (COR). This limits golf clubs to have a COR less than 0.830.Increasing COR will increase the ball’s initial rebound velocity. Thus, the golf shot should travel farther.solutionThe objective was to obtain the maximum possible COR for a new club head while maintaining a mass of 200gand keeping club head stress levels pre-defined limits. To achieve this, a programme of analytical optimisationtechniques more commonly found in the aerospace or automotive markets were employed by Altair ProductDesign.During the study, three different shape variables for the optimization process were defined for the club head: longerin the toe-to-heel sense, wider in the face-to-back sense and taller. In addition, 10 size variables were defined inthe optimization problem. The club face was divided up into five regions in a bulls-eye pattern while the remainderof the club head was divided into five other regions. All regions were defined as optimization variables and runthrough Altair’s own optimization software, HyperStudy, with the results interpreted by Altair ProductDesign’sengineering team.resultThe combination of shape and size optimization by Altair ProductDesign greatly enhanced the COR of the new clubresulting in a golf ball that travels farther while maintaining a good golf head shape that remains consistent withclub standards. By implementing virtual design concepts and optimization techniques in the concept design stageenabled the client to save development time and money in the downstream prototype build and test phases.www.altairproductdesign.com A division of
