ABSTRACT:
An apparatus and method for the testing and evaluation of numerous actuators having different load characteristics. The apparatus comprises a fixed frame, having a first and second lever arms pivotally attached to the fixed frame. An expandable, contractible spring element is pivotally connected between the first and the second lever arms functioning to transmit forces between the first and the second lever arms. A force is applied to the second lever arm and an actuator under test which is pivotally attached to the first lever arm constrains displacement of the first lever arm. A computer measures and records the displacements of the first and the second lever arms from a known starting position.
