- Abstract: This paper presents the resonant frequencies of a helical spring manually calculated in compliance with SAE-11 and also via numerical simulation. In both calculations, a damper rate of zero was utilized to make modeling simpler. Two numerical simulations were run, ranging in frequency from 90 to 590 Hz. The first simulation applied frequencies with no load on the spring, while a second simulation had an axial load on the spring grounded surface, perpendicular to spring centerline. In addition, the second simulation had a constraint added to the opposite grounded surface of the spring and was opposite to the load. Likewise, manual calculation and numerical simulation via COMSOL™ Multiphysics presented very similar results. But, when comparing only the simulations, both revealed high stresses for the same frequencies. However, the second simulation (spring with load applied) had very high stresses, which indicates a high risk of premature failure of the spring.
