Based on pseudo damage equivalent principle, converted the wheel transducer force to the program load spectrum, then built a load spectrum for the suspension fatigue bench test, which has the equivalent damage with the durability test in proving ground. To ensure the consistency of the pseudo damage, the component true damage is consistent. First, through rain flow counting, got the relation curve in the double logarithmic coordinate system between amplitude and time for the wheel transducer force, and found a straight line that more or less matches as much as possible the highest part of the curve, then the slope of straight line is as the slope of SN curve for counting pseudo damage, and the intercept of SN curve is not less than the maximum amplitude. Finally, through comparative study of the result of suspension fatigue bench test and proving ground durability test, the fatigue life is found to agree well with each other, which demonstrate the effectiveness of the presented method.
