논문 초록 (Abstract)

From a global perspective, Korea is a leader in the field of indoor screen golf technologies. However, some products and technologies that are being used in current indoor screen golf systems have shortcomings with regard to technical stability. Nowadays, hydraulic actuators are widely used in golf swing plate systems to adjust the plate and recreate for the player the slope of the terrain shown on the screen. However, the hydraulic actuators used in screen golf systems have disadvantages associated with them, such as oil leakage, bad control, and high price. To address what we perceive to be a shortage of existing alternatives, we developed a golf swing plate that uses screw actuators to drive the swing plate up and down. We take the opportunity in this study to perform an analysis of the kinematic behavior of our design employing three active PRS (Prismatic joint–revolute joint–spherical joint) legs that provide the golf swing plate with three degrees of freedom. In this paper, we focus on the derivation of kinematic equations and constraints related to kinematic variables. Furthermore, we derive the amount of translation necessary for each prismatic joint to achieve the motions required of the golf swing plate. We go on to verify the complex movement of the swing plate using the NX motion simulation program. Finally, we construct a prototype and test the functions of the golf swing plate.
