A STUDY ON THE EVALUATION OF SHOCK ABSORBING PERFORMANCE FOR DOMESTIC ARTIFICIAL TURF GROUND

This paper deals with a device and method for measuring the impact properties of artificial turf surface using the accelerometer. Recently, the number of artificial turf ground is increasing according to holding a variety of international games and change of school play ground to artificial turf from clay. Artificial turf ground is required to meet standard certification to play international game. This standard certification is given by shock performance test during the specified period. The automatic shock evaluation system for shock absorbing performance test of artificial turf ground is proposed. This system consisted of auto carriage moving module, auto shock performance testing module, and auto data acquisition. Experiment is conducted to verify the performance of developed automatic shock evaluation system for shock absorbing performance test of artificial turf ground. From the performance test, developed automatic shock evaluation system has drop height of 55mm with resolution of 0.5mm, resolution of +/- 1% for operating range, measuring acceleration of over 50g, sampling frequency of over 10kHz, image resolution of over 12bit.
