摘要
从零件表面产生热疲劳裂纹的机理入手 ,延用波的传播理论 ,研究了柴油机内壁的温度振荡和交变热应力 。
Through illustrating the principle of the thermal fatigue crack in the surface of machine parts, and using the wave spreading theory, the paper focuses on the temperature oscillation in the wall of Combustion Chamber of diesel engine and the effects of the alternating thermal stress on the surface of machine parts, and then puts forward how to decrease the destructive effects.
