论文摘要
由麦肯齐（Mackenzie）观察一对负面力量夫妇的动力，本文探讨了高尔夫俱乐部如何移动影响的模型。它假设高尔夫俱乐部作为双摆的远端臂正在移动。在撞击时，俱乐部头正以指定曲率半径的路径，以最大速度向下行驶。从这个模型中，计算了将俱乐部移动到撞击附近所需的力和扭矩。接近撞击的负面夫妇是该模型的强大功能，平衡了与驱动高尔夫俱乐部质量中心的力相关的扭矩。负面的夫妇允许高尔夫球手在撞击时保持更大的弯曲曲率半径。 由于负面的夫妇也可以降低俱乐部的旋转速度，因此在高尔夫挥杆中受到影响的负面夫妇的存在表现出距离和方向之间的贸易。
Motivated by MacKenzie's observation of a negative force couple near to impact, this paper explores a model for how the golf club moves near to impact. It assumes the golf club is moving as the distal arm of a double pendulum. At impact the club head is moving straight down the target line, at its maximum speed, on a path with a specified radius of curvature. From this model the forces and torques required to move the club near to impact are calculated. The negative couple near to impact is a robust feature of this model, balancing the torque associated with the force that drives the center of mass of the golf club. The negative couple allows the golfer to maintain a larger radius of curvature of the path of the club head as it moves through impact. Because the negative couple can also serve to reduce the rotational speed of the club, the presence of a negative couple at impact in the golf swing manifests a trade between distance and direction.
