Multiposition Machine for Testing Flat Specimens for Fatigue

摘要

The object of the invention is a multiposition machine for testing flat specimens for fatigue with sign-varying (between plus and minus) bending consisting of a ring-shaped vibrator with changeable cam disks for creating in each specimen varying stresses which vary in magnitude, and an electric heater for heating the specimens being tested. For the purpose of changing the specimens being tested without stopping the machine, it is provided with removable tail spindles radially arranged around a ring-shaped vibrator and which serve for fastening the specimens that are being tested.
