Simulation of Fatigue Strength of Non Limit Aluminium Alloy Locator
The fatigue strength of the contact wire locator is an important technical indicator that affects its service safety.Based on the analysis of the fatigue characteristics of a certain type of non limiting aluminum alloy locator a-broad,fatigue tests were conducted on the locator,and the stress cycle times of the locator were obtained under three different working conditions.The fatigue strengths of dangerous sections of the positioner under various operating con-ditions were verigied using finite element method,and its fatigue life was estimated.The simulation result is identical to the experimental result,which shows that use of the finite element method is effective and feasible.This study will offer a guarantee for safe use of France's high speed positioners in China,and it is of guiding significance for research on working performance of positioners and evaluation of its optimization design effect.
