Performance Difference with Respect to the Number of Wheels on the Cricket Bowling Machine

摘要

Cricket is one of the sports played in Malaysia. The national team is under the supervision of the Malaysia Cricket Association (MCA). Currently, most the player training is done manually. Therefore, this study focuses on the development of the cricket bowling machine as a mean to ease the training session as well as analyzing the machine's performance through experimental data. Two machines have been designed and fabricated to analyze the difference in performance between a single rotating wheel mechanism and two counter rotating wheel mechanism to propel the ball. The ball speed ratio is based on the linear wheel speed. As the wheel speed increases, the single-wheel ball speed ratio ranged from 47 to 50 % with a gradient of -0.0032. On the other hand, the two-wheel ball speed ratio ranged from 68 to 95 % with a gradient of -0.0245.
