“…This is nothing but a graphical mirage, due to the choice of S max as the relevant load amplitude for the Gassner plot. According to [12], it may be proven [11] where SSF stands for spectrum shape factor, which solely depends on the shape of the spectrum and the Basquin slope. Please note that if the spectrum collapses to a constant amplitude load (i.e.…”

Abstract. High cycle fatigue behaviour of materials is historically assessed with constant amplitude and variable amplitude loads, respectively. Thus, a long-lasting debate is extremely active in the academic community, trying to link experimental results coming from these different approaches. Overcoming all this, since the 1970s several industrial fields have been choosing to consider representative customer load spectra (in terms of amplitude, not frequency) as the best way to test both materials and structures. In particular, the automotive industry makes use of specific car loading spectra, regularly fed by the customer knowledge and practised on proving grounds. This paper presents a highlight on such spectra, neglecting any sequence effect of the load time history, thus accepting the Palmgren-Miner's rule as an assumption. Whereas a recent communication on this very topic focused on the basic occurrence spectra, which is absolutely independent from the material properties of the car parts, here we deal with the final damage assessment. Obviously, it is worth knowing which part of the spectrum is mainly responsible for the most relevant fatigue damage.

“…This and other similar sources (e.g. Berger et al, 2002) do not offer an integrated, holistic representation of the durability assessment process, applicable to the entire ground-vehicle industry, but with sufficient detail so as to include as components the different choices of methods for determining input loading, performing stress analysis and performing fatigue analysis, as well as to represent the various permutations of methods that would be viable for performing durability assessment. This paper proposes a framework for mapping numerical methods and methodologies for the durability assessment of vehicle and transport structures.…”

Numerical methodologies for assessing the durability of vehicle and transport structures are reviewed. These methodologies are mapped in terms of a framework that emphasizes the relationships among them. Load inputs are obtained from either measurements or simulation. These loads are used as inputs into stress analyses, which may be either quasi-static or dynamic, and either in the time domain or in the frequency domain. The outputs of these analyses can then be used in fatigue analyses. The advantages and disadvantages of each method are analysed. A case study is described to demonstrate the insights gained from the mapping framework.

“…The automotive industry is expending constant effort in correlating proving ground loading conditions with the customer profiles, or alternatively employs standardised load-time histories, also derived from extensive field measurements [3]. In the heavy vehicle industry and particularly for special vehicles, such information is not always readily available and the need for economical methods to describe loading conditions for design purposes, is apparent.…”

a b s t r a c tIt is common practice in the automotive industry to employ multi-parameter strain-life methods, in combination with dynamic finite element analyses, based on very extensive measurement exercises, to conduct analytical fatigue life assessments, which is then verified through intensive durability testing. The expense and complexity of this approach makes its application impractical for low volume ''special" vehicles. In this paper, a fatigue equivalent static load (FESL) methodology for the numerical durability assessment of heavy vehicle structures is presented, where fatigue load requirements are derived from measurements as quasi-static g-loads, the responses to which are considered as stress ranges applied a said number of times during the lifetime of the structure. The application of the method is demonstrated using two case studies, namely a road tanker and a load haul dumper. In both cases, it was possible to obtain adequately accurate fatigue life prediction results, using simplified loading, static finite element analyses and a stress-life approach to fatigue damage calculations, with material properties available in design codes.
