Abstract
An impact wear testing device comprises a driven member mounted for controlled oscillations along an axis and a rotatably mounted support member having an impact portion aligned with the driven member axis. The driven member oscillates so that one end thereof periodically contacts the support member impact portion. The wear testing device has means for mounting a specimen to be tested on either the end of the driven member or support member impact portion and a force measuring device disposed on the other of these two elements. Control means may be provided to monitor the output of the force measuring device and to vary the driven member oscillations to maintain the peak impact force at a constant value. The force measuring device is preferably a time responsive piezoelectric transducer, and may have means for mounting a test specimen thereto to provide two body impact wear testing.
