Effect of the fatigue data editing technique associated with finite element analysis on the component fatigue design period

Influence of tire sizes over automobile body spectrum loads and fatigue damage accumulation

“…These spectra are also qualitatively similar to the ones measured in other automotive parts, as reported by Zakaria et al [9] in the case of the engine mount bracket of a passenger's vehicle and by Kadhim et al [10] in the case of as lower suspension arm. Petracconi et al [11] also instrumented a tow hook assembly of a passenger's vehicle, obtaining a spectrum with qualitative similarities to the ones obtained in the present work.…”

Generation and validation of loading profiles for highly accelerated durability tests of ground vehicle components

“…Time-domain-based techniques include short-time-Fourier transform [5], time correlated fatigue damage [6], strain gauge editing technique [7][8][9] and racetrack editing technique [10]. All these techniques broadly termed as 'fatigue damage editing' which is a signal processing technique.…”

“…In such a technique, the signal (the time-history of the strain, acceleration, or displacement) is collected from the field tests via sensors like strain gauges, accelerometers, or LVDTs, and edited to retain the desired percentage of the damaging portion of the signal. In these techniques [5][6][7][8][9][10], non-damaging or less damaging parts (according to the stress life curve of the material) are removed from the signal hence accelerate the tests. To perform the test in the laboratory, the edited acceleration or displacement signal is implemented to the shaker tables [8].…”

“…Moreover, the theories have been well established and rich experimental data are also available in this technique. However, the AF cannot be truly controlled in the time-domain-based techniques since the AF mostly depends upon the severity of the acceleration, displacement or strain data collected from the durability track [6][7][8][9][10]. Moreover, time-domain-based techniques are relatively computationally expensive than the frequency-domain-based techniques [11].…”
