| Abstract: | The research object of this paper is cylinder head for diesel engine S195 .On the ground of probability and statistics theory, a safe operational life related to degree of believe and confidence level during the accelerated thermal fatigue test is estimated. The result is very important to resonaby determine the repairing interval and the maintenance interval of such heated parts in the diesel engine as cylinder head. |
