  1. 1. Modal and Fatigue Analysis of the Stratotimer

    University essay from KTH/Lättkonstruktioner

    Author : Gabriele Busseti; [2019]
    Keywords : ;

    Abstract : Fatigue analysis of the printed circuit boards (PCBs) of an avionic instrument has been analyzed. The natural frequency and transmissibility has been estimated through analytical approach and finite element approach with Solid- Works and experimentally. READ MORE

  2. 2. Transient and Spectral Fatigue Analysis for Random Base Excitation

    University essay from Chalmers tekniska högskola / Institutionen för mekanik och maritima vetenskaper

    Author : Albin Bäckstrand; Prithviraj Madhava Acharya; [2019]
    Keywords : Spectral fatigue analysis; transient fatigue analysis; power spectral density PSD ; transfer function; base excitation; Dirlik s empirical formula; equivalent von Mises stress EVMS ; rainflow count; Wang and Brown s method; Dang Van equivalent stress; Palmgren-Miner rule;

    Abstract : This thesis work gives an insight on how to estimate the fatigue damage using transient and spectral fatigue analysis for both uniaxial and multiaxial stress states in case of random vibration base excitation. The transient method involves a rainflow count algorithm that counts the number of cycles causing the fatigue damage, while the spectral method is based on probabilistic assumptions from which an expected value of fatigue damage can be estimated.
