Abstract:

Two test stands were designed and built to aid in the evaluation of prosthetic systems and components. The first, a systems test stand, yields time data on AE prosthetic system performance. The second, a component test stand is specifically designed for the determination of actuator force-length relationships. The systems test stand consists of elbow, forearm, VO hook, and dual cable control, and is powered by 2 BPAs, connected in tandem. The test specimen is operated from the control chassis, while performance data are obtained from special transducers in the system and from electrical connections in the control circuit. The component test stand incorporates a force transducer, a velocity transducer, a loading platform, and a variable damper. Weight loading of the test actuator can be replaced by constant force spring loading where inertia effects are not desired. This test stand will make possible the comparative evaluation of prosthesis actuators under widely variable conditions of loading and damping. Author
