Fuzzy Resonance Reliability Analysis of the Multi-freedom Vibration System

According to the relationship between the natural frequency of a system and the excitation frequency, the resonance rule of fuzzy failure for the multi-freedom vibration system is built. The fuzzy resonance reliability of vibration system based on the importance sampling method has a more reasonable measurement of the probability of vibration system on resonant failure. The example on fuzzy resonance reliability analysis of the body-wheel-road system is presented to illustrate its engineering application.
