ゴルフボール接触状態の観察手法

抄録

In previous study, quantitative relationship between slip magnitude under driver shot impact and back spin rate was analyzed. For confirming the theory, measurement system which can observe the slip magnitude in 0.5msec contact phenomena was constructed. The system could capture the slip phenomena clearly, and by the result, the slip magnitude vary from 0.3mm to 1.5mm by changing contact surface friction property. The difference of back spin rate and the relationship between slip and backspin is roughly correct with proposed mathematical model.
