High Frequency Resonance Test Machine (Pulsator)
ARAI has recently installed High Frequency Resonance test Machine pulsator) at Structural Dynamics Lab. The machine works on the resonance principle. The machine is designed as a three-mass swing system and includes additional screw-on masses in order to be used to influence the test frequency.
This machine is of maximum 250kN capacity. This machine is useful for testing of high stiffness components such as connecting rod, crankshaft, bolts, Brackets, Gear teeth, Knuckle etc. With the introduction of this machine, the test duration can be reduced significantly since test frequency of machine can go as high as 100 Hz depending on the stiffness of the test component.
E-motion software of the machine is useful to conduct the Static, Single Load & Block Program tests. One of the most important features of this machine is that it could detect crack initiation at very early stage as the resonance frequency will change with crack initiation in the test component. Software has facility to detect frequency variation and to terminate the test or to study crack propagation behavior.
