Abstract

The work aims to study the influence of vibration characteristics, vibration acceleration, vibration frequency and othervibration parameters on the injury of Huangguan pear under the stationary vibration system, and establish the model for the relationship between the injury rates of Huangguan pear area and volume and the time, through its vibration test. Based on the sweep scanning and fixed frequency testsin the stationary vibration, the relationship between Huangguan pear vibration acceleration, resonance frequency andenergy transfer rate was analyzed. The change law of injury rates of Huangguan pear area and volume was studied. The resonance frequency of Huanggu pear decreased with the increase in the acceleration, and itbasically had no obvious change after 0.85g. The change trend of resonance frequency of Huanggu pear from the bottom up was similar in each layer (7 layers in total). With the increase in the vibration acceleration, both the resonance frequency and the energy transfer rate of Huangguan pear in a single layer become smaller. The acceleration and the resonance frequency of Huangguan pear in a single layer is in a nonlinear relationship. The injury rates of Huangguan pear area and volume in multiple layers become bigger with the increase in the layer number. The resonance frequency decreases with the increase in the layer number.
