Bolting frequency

WebFor one example, the bolt itself is tested for strength by the manufacturer by screwing the bolt into a standard testing fixture and subjecting it to pure tension. However, in typical applications, bolt tension is induced by torque on the nut and the bolt is subject to combined tension and torque, which may cause the bolt to fail at a load less ... WebApr 21, 2024 · Unless it is not possible to push the resonance out from the test frequency range, then we may want to use the Frequency Response Simulation. Running frequency response simulation will be much more challenging compare to normal mode since the accuracy of the result will not be depending only on mass and stiffness, but also the …
