Summary: <ul><li>Enhanced Ball Path Simulator - Computerized Ball Path </li></ul><ul><li>A virtual Plant Tour- Video of Ball Production </li></ul><ul><li>Breaking down Columbia 300's Coverstocks </li></ul><ul><li>How the Full Throttle fits in our line </li></ul><ul><li>Questions & Answers </li></ul>
3. 3. New Ball Path Simulator <ul><li>Mathematical model of the ball path </li></ul><ul><li>Uses C.A.T.S. TM data as input along with new friction data </li></ul><ul><li>End result is an accurate prediction for bowling </li></ul><ul><li>Study of the physics of bowling </li></ul>
4. 4. Ball Path Simulator Program Input Data Out Data
5. 5. Arc of the Ball Track 3/4 Roller- Approximately 8-12”arc Large axis tilt (10-35 0 ) 8-12” arc 13.5” arc Full Roller- Approximately 13.5”arc Close to 0 0 axis tilt
6. 6. Defining Rotational Force with 90 Degree Axis Rotation rotation Rotation force proportional to RPM and Rg
7. 7. All Forces with 90 Degree Axis Rotation Velocity Rotation Rotation Resultant force Angle change, or total angle Roll out
8. 8. 45 Degree Axis Rotation Angle 45 deg. Rotational Force Velocity Resultant Force Angle Change less than with 90 degree
