Criteria of structural durability proof regarding testing time for substituting of steel by aluminium components by the example of commercial vehicle wheels

Abstract: Der experimentelle Nachweis der Betriebsfestigkeit von Sicherheitsbauteilen stützt sich auf eine schädigungsäquivalente Reduzierung des Bemessungskollektives auf ein Versuchskollektiv mit verkürztem Umfang unter Berücksichtigung statistisch begründeter Sicherheitsfaktoren. Historisch bedingt, wurden entsprechende Versuchskollektive zunächst für Bauteile aus Stahl anhand von Wöhlerlinien für Stahl, durch Anwendung der Palmgren-Miner Regel mit der Modifikation nach Haibach, vorgenommen. Bei der späteren Einführu… Show more

“…For this, beside the knowledge of the load related probability of occurrence P o, Load of the spectrum, also the knowledge of the Gassner-line with the strength related probability of failure P f, Strength of the component or structure is necessary, Figure 4. This is determined from the strength related probability of survival P s, Strength : P f; Strength ¼ 1À P s; Strength (4) From the interaction between the load related probability of occurrence P o, Load of the spectrum and the strength related probability of failure P f, Strength the service related theoretical probability of failure P f, Service is calculated [13]:…”

“…The factor f t considers the influence of manufacturingrelated dimensional fluctuations on the load capacity and consequently on fatigue life. The substitution of steel by aluminium is respectively covered by f St/Al = 1.25 Figure 6, Table 2 [3,4,12]. In case of a salt corrosion, for the durability proof of aluminium components in air without the corrosive environment a prolongation factor of f Corrosion = 2 to 3 is recommended for the compensation of the corrosive influence on the fatigue life, Figure 7 [9,11].…”
