Based on the resonance phenomenon of lumbar spine,this paper explores a method to predict the natural frequency of lumbar spine,so as to provide help for the optimization of external vibration sources,so as to avoid the occurrence of lumbar spine resonance.At the same time,according to the finite element model of lumbar spine,the dynamic finite element analysis was carried out by applying vibration loads with different exciting frequencies,and the exciting frequency(resonance)which caused the most significant changes in its mechanical parameters was found,and the frequency should be close to the natural frequency of lumbar spine.The results show that the natural frequency of the model is 7 Hz.
