| Abstract: | To study random vibration fatigue life of electronic products, the virtual prototype technology and random vibration fatigue model is applied to evaluate the random vibration fatigue life of devices and circuit board. This paper mainly introduces the specific process of virtual evaluation method for random vibration fatigue life based on virtual electronic products. Finally, it analyzes the random vibration fatigue life by taking the specific circuit board as the example. |
