neodymium magnets - Opis:
- This article proposes a method and a laboratory setup for testing the fatigue strength of materials with the use of vibration signals and a neodymium fatigue-testing machine. The machine supports non-contact fatigue testing of construction materials, and analyses of bending and torsional behaviour of magnetic and non-magnetic materials at any excitation range. The discussed machine is a non-contact bending device, and when an appropriate adapter is used, it supports analyses of torsional behaviour in determinations of material wear. A neodymium fatigue-testing machine can also be used to evaluate sample deformation by registering amplitude, RMS deviation from equilibriumcalculated values, temperature of sample notch, deflections along the length of the sample, stress at the cross-section of the notch and load applied at the terminal section of the sample. Simplified diagram of a rotating-bending fatigue testing machine, diagrams of biaxial rotating-bending fatigue testing machines, diagrams of a bending fatigue testing machine, displacement range of a material point in the sample induced by neodymium magnets on a double disc, displacement range of a material point in the sample at rotational frequency, displacement range of a material point in the sample at rotational frequency, changes in the sample's notch temperature and displacement amplitude are presented in the paper.
