Motion Platform  The motion platform will be created by modifying an existing Quasi- Motion™ Servo Controlled Tipper Platform.  The platform will be extended to approximately 6’ x 8’.  The extension will most likely be raised about a foot over the original tipper with supports attaching to the corners of the platform.  The platform must be raised up far enough so that it doesn’t hit the floor during tipping.  A diagram of motion will be drawn up to show the range of motion of the tipping platform.

Design Considerations for the Motion Platform Pivot Point Pivot Point One of the main factors to affect the realism of motion.One of the main factors to affect the realism of motion.

Balancing Masses Balancing Masses Since most of the weight will be in the front of the cabin, balancing masses will be provided in the rear.Since most of the weight will be in the front of the cabin, balancing masses will be provided in the rear.

Spacing of Bellows Spacing of Bellows Since the bellows have a finite strength with which to lift the cabin, they may need to be spaced further out.Since the bellows have a finite strength with which to lift the cabin, they may need to be spaced further out. This would require modification of the motion platform, and will be avoided if possible. This would require modification of the motion platform, and will be avoided if possible. Spaced bellows will be able to support more weight, but won’t be able to move the cabin as much.Spaced bellows will be able to support more weight, but won’t be able to move the cabin as much.
