1. 1. Reliability-Based Sensitivity Analysis of the Dynamic Response of Railway Bridges

   University essay from KTH/Bro- och stålbyggnad

   Author : Hasan Al-Zubaidi; [2022]
   Keywords : Railway bridges; High-speed trains; Simply supported beam; Global sensitivity analysis; Uncertainty quantification; Reliability; Ballast instability; Running safety; Passenger comfort;

   Abstract : In response to the planned increase in operational speeds and axle loads of passengertrains that may lead to resonance-induced excessive vibrations in railway bridges,recent studies examined the reliability of bridges concerning train running safety andpassenger comfort limit states. In this respect, valuable information regarding theimportance of input variables can be obtained by conducting Sensitivity Analysis (SA). READ MORE

3. 2. Statistical Assessment of Uncertainties Pertaining to Uniaxial Vibration Testing and Required Test Margin for Fatigue Life Verification

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Davood Dehgan Banadaki; Sunay Sami Durmush; Sharif Zahiri; [2013]
   Keywords : Vibration Testing; FEA; Natural Frequency; Deterministic and Random Vibrations; Fatigue;

   Abstract : In the automotive industry uniaxial vibration testing is a common method used to predict the lifetime of components. In reality truck components work under multiaxial loads meaning that the excitation is multiaxial. A common method to account for the multiaxial effect is to apply a safety margin to the uniaxial test results. READ MORE
