Correlated and coherent analysis based on vibration data of fatigue life test rig for ball with three point contact
The exciting input signals of the parts in a fatigue life test rig for ball with three point contact and the systems output signals were analyzed by auto-correlation and cross-correlation with MATLAB software,which eliminated the impact of noise to a certain extent and got the response signals of same fiequencies caused by exciting input signals.Finally,the result showed that the text rig was linear by coherent function analysis,which provided the theory basis for modal and dynamic analysis further.
