FLAT BELT TESTER WITH MOVING ENDLESS SUPPORT MEMBER
20230341295 · 2023-10-26 ·

A testing machine for rotating test specimens includes a frame and a roadway assembly. The roadway assembly includes an endless belt that provides a surface for engaging the test specimen and is supported by and rolls on rollers. An endless support member supported by the frame is disposed between the rollers and engages the endless belt from below. The endless support member moves with or is synchronized so as to have a velocity the same as the endless belt. The endless support member provides a flat reaction structure for loads from the test specimen placed on the endless belt and is of size corresponding to that needed by the contact patch of the test specimen upon the endless belt. Since the endless support member moves at the same velocity as the endless belt no forces are generated between the endless support member and the endless belt.
