| 摘要 |
The invention provides a simulator or measurement apparatus for use in a bail game where a ball is hit from a stationary position. The apparatus includes a bail ( 2 ), a connecting means ( 1 ), a base ( 48 ) and a measurement means. The ball ( 2 ) is connected by the connecting means ( 1 ) to the base ( 48 ). The connecting means ( 1 ) operates to provide a number of degrees of freedom to the movement of the ball ( 2 ), and is in a unique arrangement for each position of the bail. It operates to allow the bail ( 2 ), when struck by an object, to substantially replicate some or ail of the motion characteristics of an unconnected ball, over a distance sufficient to measure such motion characteristics. The measurement means measures motion characteristics of the connected ball ( 2 ) over the distance when such motion characteristics are substantially replicated.
