Occurring resonance may negatively affect the health of the human lumbar spine.
Hence, vibration generated in working and living environments should be optimized to avoid resonance when identifying the natural frequency of the human lumbar spine.
The range of the natural frequency of the human lumbar spine has been investigated, but its specific numerical value has not been determined yet.
This study aimed at presenting an approach based on resonance for predicting the specific numerical value of the natural frequency of the human lumbar spine.
The changes in the numerical fluctuation amplitudes and the cycles of lumbar mechanical parameters during resonance are greater than those during nonresonant vibration.
Given that the range of the natural frequency has been identified, vibrations at different excitation frequencies within this range can be applied in a human lumbar finite element model for dynamic finite element analysis.
When the excitation frequency is close to the natural frequency, resonance occurs, causing great changes in the numerical fluctuation amplitudes and the cycles of lumbar mechanical parameters.
Therefore, the natural frequency of the lumbar finite element model could be back-calculated.
Results showed that the natural frequency of the established model was 3.5 Hz.
Meanwhile, the closer the excitation frequency was to the natural frequency, the greater the changes in the numerical fluctuation amplitudes and cycles in the parameters would be.
This study presented an approach for predicting the specific numerical value of the natural frequency of the human lumbar spine.
Identifying the natural frequency assists in finding preventive measures for lumbar injury caused by vibration and in designing the vibration source in working and living environments to avoid approximating to the natural frequency of the human lumbar spine.
