SOME ENGINEERING CALCULATION METHODS OF STRUCTURAL VIBRATION FATIGUE LIFE

摘要：

Structural vibration fatigue is one of most important factors in influencing structural integrity. Currently, the static strength design and dynamic strength checking method is used in astronautics field, which means the structural fatigue life is calculated using static fatigue strength method when designing the product. The probable vibration damage is commonly checked by the vibration test with the static fatigue design, but without the vibration fatigue design. So, if the vibration test failed, redesign must be taken, which is blindness. In this paper we present the engineering calculation methods of the structural vibration fatigue life. Including a method for common random vibration fatigue analysis based on the sine resonance S-N curves and a method for the random vibration fatigue damage calculation by the sonic fatigue analysis method.
