Forward dynamics golf swing simulations are important to gain insight into how a golfer should swing a particular club and which design improvements should be considered by golf club manufacturers. A new method of optimizing a four degree-of-freedom (DoF) biomechanical golfer model swinging a flexible shaft with a rigid clubhead was developed using a direct orthogonal collocation approach. The kinematic and kinetic results of the simulation confirm previous findings on optimal joint angle trajectories, shaft deflection patterns, and joint torque profiles in a golf swing. This optimization approach is a promising development in biomechanics research, and future work will implement this method in three-dimensional swing models that have been shown to have higher robustness and fidelity.

前向动力学高尔夫挥杆模拟对于洞察高尔夫球手应如何挥杆特定球杆以及高尔夫球杆制造商应考虑哪些设计改进非常重要。使用直接正交配置方法，开发了一种优化四自由度（DoF）生物力学高尔夫球手模型的方法，该模型使具有刚性杆头的柔性杆摆动。仿真的运动学和动力学结果证实了先前在高尔夫球挥杆中最佳接头角度轨迹，杆身偏转模式和接头扭矩曲线上的发现。这种优化方法是生物力学研究中有希望的发展，将来的工作将在已证明具有更高鲁棒性和保真度的三维摆动模型中实现此方法。
