Abstract
The present disclosure relates to a system for repetitive loading of a prosthetic socket to test the durability of the prosthetic socket. The system includes a base and a load cell coupled to the base. The system further includes a first coupling mechanism positioned vertically above the load cell, and a second coupling mechanism positioned vertically above the first coupling mechanism. The first coupling mechanism is configured to be removably coupled to a first end of the prosthetic socket, and the second coupling mechanism is configured to be removably coupled to a second end of the prosthetic socket. The system further includes a rod having a first end and a second end opposite the first end. The first end of the rod is coupled to the second coupling mechanism. The system further includes a motor coupled to the second end of the rod, a support structure extending vertically from the base, and an actuator coupled to the support structure such that the actuator is positioned vertically above the second coupling mechanism. The system further includes a curved rail coupled to the actuator and positioned between the actuator and the second coupling mechanism. The curved rail is configured to contact the second coupling mechanism along an arc defined by the curved rail such that the second coupling mechanism moves along the arc when the motor moves the rod.
