It is one of the important design assessment items to evaluate the fatigue life for the exhaust system of automobile. For this purpose, It is necessary to describe reliable load spectrum expected in the real operation of automobile. A study of the development procedure of driving load spectrum for the exhaust system of automobile. And the analysis of welded part was also made to obtain the local strain spectrum on the site where the fatigue damages are anticipated. These results are applicable to analyze the fatigue life and to perform the fatigue test for the exhaust system of automobiles.
