Abstract
A novel Stewart platform includes electromagnetic linear actuators. The motion platform may be included in an apparatus and method for testing footwear where a stationary shoe is struck by the motion platform.
Claims12
A shoe testing apparatus comprising:
- (a) a fixed artificial foot for wearing the shoe, wherein the artificial foot is mounted to a force sensor;
- (b) a motion platform having 6 degrees of freedom of movement;
- (c) means for actuating the motion platform and striking the shoe with the platform in a manner simulating the running or walking gait of a shoe wearer;
- and
- (d) means for recording the forces transmitted through the shoe to the artificial foot and sensed by the force sensor.

A method of testing a shoe comprising the steps of:
- (a) fitting an artificial foot within the shoe, providing a force sensor attached to the artificial foot and fixing the foot and shoe in position;
- (b) providing a motion platform having 6 degrees of freedom of movement;
- (c) providing a foot trajectory and transforming the foot trajectory to a platform trajectory;
- (d) actuating the motion platform with the platform trajectory to strike the shoe;
- and
- (e) recording the force transmitted through the shoe to the artificial foot with the force sensor.
