Fatigue assessment and reliability in automotive design

The analytical design process and diesel engine system design

“…More in-depth discussions on reliability in engine system design are provided in Chapter 2. The fundamentals on reliability can be found in Ireson et al (1996), Bignonnet and Thomas (2001), Kuehnel et al (2005), Dodson and Schwab (2006), Klyatis and Klyatis (2006), Rahman et al (2007), Zhou and Li (2009), and Klyatis (2010).…”

Durability and reliability in diesel engine system design

“…The loads can create multi-axial stresses in the engine component due to external loads, residue stresses and the geometry of the structure (Bignonnet and Thomas, 2001). Although in many cases a calculation of uni-axial stresses is sufficient for preliminary analysis, FEA is required to calculate the stresses under multi-axial loads together with the complex geometry of the component.…”

“…They claimed that the Monte Carlo simulation could obtain the same result but with 500 times longer computing time than their Fast Probability Integration software developed at the Southwest Research Institute. Bignonnet and Thomas (2001) used the statistical stress-strength model to predict the reliability of automotive components related to fatigue. Niewczas and Koszalka (2002) presented a method for reliability prediction related to engine cylinder liner wear and power cylinder durability.…”

Comparing in-service multi-input loads applied on non-stiff components submitted to vibration fatigue to provide specifications for robust design

“…At that time, little information on the new concepts, regarding geometry and material, is known (Johannesson & Speckert, 2014). For static or quasi static structures, equivalent loads are usually helpful to describe univariate or multivariate loads (Bignonnet & Thomas, 2001) (Le Corre (Genet), 2006). For non-stiff components, input loads can be described with power spectral densities.…”
