ABSTRACT:
The invention is a machine for the cyclic load testing in tension, compression, torsion, shear, or any combination thereof of any one of a number of different sizes, types and configurations of test specimens at a fixed or adjustable predetermined load and cycle rate and comprising a machine frame in which is mounted a drive shaft, any number of intermediate shafts as required, and a camshaft or crankshaft. At the workstation of the machine, appropriate fixtures and tooling are either fixed, rotating, or in motion, as required to conduct the particular test to be performed. When the test specimen is to be in motion, the motion may be derived from a driving source separate from the primary mover or camshaft, for instance but not limited to an independent motor or cylinder. This source of motion may also be taken through a drive train or any suitable means from the same driving source as the camshaft or from the camshaft itself or from any other moving member in the system. A motion is ultimately imparted to drive the test specimen holder, thereby setting the test specimen in motion.
