Methodology for the Safe and Economical Fatigue Design of Components in ABS/ETC Braking Systems Under Variable Amplitude Loadings

The paper presents first how load spectra of antilock brake and electronic traction control systems (ABS/ETC) are obtained from braking pressure simulation in special test benches for particular vehicles of different customers. Subsequently, the measures for the derivation of a test spectrum under consideration of a reasonable test time reduction are described. Finally, the experimental and numerical procedures for fatigue life and safety assessments of the ABC/ETC hydraulic housings are presented.
