How Professional Equipment Quantifies the On-Course Performance of Golf Balls
Club Calibration:
Prior to testing, strict calibration of the golf club is required, including adjustments to parameters such as clubface angle, clubhead sweet spot position, and shaft flex. A standard test ball is used for pre-hitting to verify whether the robotic arm's movements comply with the preset parameters. Calibration data is entered into the system as a benchmark reference for subsequent tests, ensuring the consistency and repeatability of test conditions.
Equipment Debugging:
The debugging content includes robotic arm movement range testing, sensor signal calibration, and camera focus adjustment. Through multiple dry-fire tests, the equipment's operating status is verified, and issues such as mechanical jamming or signal interference are eliminated. After the debugging is completed, the system automatically generates an equipment status report to confirm that the equipment is in optimal working condition, laying a foundation for formal testing.
Hitting Parameter Settings:
Based on the test objectives, set hitting parameters such as clubhead speed, impact point offset, and club loft angle. Parameters are input through the control system, and the robotic arm executes corresponding actions. Parameter settings must comply with international standards to ensure the comparability and authority of test results. Parameter data is synchronously stored to facilitate subsequent data tracing and analysis.
Ball Trajectory Analysis:
Using flight images of the golf ball captured by high-speed cameras, image processing software is employed for trajectory tracking and modeling. Key parameters such as ball trajectory height, flight distance, and landing deviation are analyzed. Combined with sensor data, the aerodynamic characteristics of the golf ball are calculated, including lift coefficient and drag coefficient. The results of trajectory analysis provide an important basis for quantifying the on-course performance of the golf ball.
Spin Rate Measurement:
A gyroscope sensor installed on the golf ball is used to real-time monitor the spin rate and axial stability of the ball after impact. Data is transmitted to the analysis system to calculate the angle between the spin axis and the flight direction, evaluating the ball's sidespin and pitch spin conditions. Spin rate directly affects the ball's flight trajectory and landing control, making it a crucial parameter for measuring ball performance.
Ball Deformation Monitoring:
High-speed cameras and strain sensors are used to monitor the deformation of the golf ball at the moment of impact. Key parameters such as the ball's compression amount, recovery time, and deformation distribution are analyzed. The data is utilized to evaluate the ball's durability and energy rebound efficiency, providing an optimization basis for the design of ball materials and structures. The deformation monitoring results can reflect the ball's impact resistance and service life in actual on-course use.
