These machines test the bending fatigue limit of metals under the action of symmetrical repeatedly.
Bending fatigue testing machine.
Specialized torsion system for rotating beam testing.
Parsros rotary bending fatigue testing machines are suitable to test the fatigue strength of metals or other.
Electrodynamic testing machines are used to determine the durability of materials and components in the finite life fatigue and high cycle fatigue ranges.
This paper presents the design and development of a fast rotating bending test machine f or high cycle fatigue.
To provide full scale testing of the fatigue performance of our products apollo designed built and commissioned the world s first large scale rotating bending fatigue tester.
Nicknamed the rotatamatron 3000 the machine is capable of applying a constant stress across a 2 75 in 70 mm diameter reduced section with a maximum load of 50 000 lbs.
This is rotating beam type machine in which load is applied in reversed bending fashion.
Rotating beam fatigue testers are one of the oldest methods used to determine a material s fatigue behavior.
Tests which can rotate up to 18 000 rpm generating cyclic s tresses at 300 hz.
Rotatory bending machine the purpose of the rotating bar bending fatigue test is to determine the bending fatigue strength properties under rotating load.
