【Abstract】 Different technology measures for improving fatigue life of submarine’s important structures are analyzed and discussed in this paper. It places emphasis on discussing a new technology measure——Ultrasonic Impact Treatment for improving fatigue life of submarine’s structure. The principle of the new technology measure and the instruments needed by the new technology measure are discussed in detaily and the key technical difficulties to be solved in order to make use of the new technology measure are pointed out. It has showed that the new technology measure is very effective in improving fatigue life of submarine’s important structures after the measure was practically used in the two different types of submarine’s important structure in Bohai Shipyard and Wuchang Shipyard.更多还原
