Three Dimensional Dynamics of the Golf Swing

A Forward Dynamics Approach with a Focus onOptimizing Shaft Stiffness

• Broschiertes Buch

Produktbeschreibung

This book establishes a comprehensive understandingof the role that shaft stiffness plays in executinga golf drive. A thorough set of experiments wasconducted to answer explicit questions related tothis goal. Specifically, how does shaft stiffnessaffect clubhead speed and how does it alter clubheadorientation at impact? What are the underlyingmechanisms responsible for the pattern of shaftdeflection occurring during the downswing? For thefirst time, a 3D, 6-segment forward dynamics modelof a golfer and club was developed to answer thesequestions. The golfer model was optimized formaximum clubhead speed using a genetic algorithmthat determined the best activation pattern for thesimulated muscles that provided energy to thesystem. High speed video data of shaft bendingduring the swings of actual golfers were collectedto assess the validity of the model. In addition tothe findings on shaft stiffness, the development ofthe model led to an understanding of the role thatpassive joint forces play in squaring the club forimpact. This book also serves as a solidintroduction to forward dynamics modelling.
