Fatigue Testing Machine
Advanced Technocracy Inc. is Manufacturer, Exporter & Supplier of Fatigue Testing Machine
Using this benchtop unit, the basic principles of fatigue testing can be conveyed. A rotating metal test bar, clamped at one end, is loaded using a spring balance with a point force. This results in a cyclic bending load on the cylindrical specimen. The amplitude of the cyclic loading can be continuously adjusted using a threaded spindle with hand wheel. After a certain number of load cycles, the specimen breaks as a result of material fatigue. In this case the machine is shut down automatically by the stop switch. The number of load cycles is counted by an electrical counter and displayed digitally. This can also be used for measuring the speed. Different shape specimens enable the influence of notching and surface finish on fatigue strength to be demonstrated.
