Abstract: The vibration model of peach was established on the rehology model of peach. According to the dynamic test foe peach’s main dynamic parameters, stiffness, damping ration and resonant frequency, were calculated. Conclusions waral drawn after analysizing the results of peachis dynamic test and peach bruise property. The conclusions can be used to design packing system of peach to decrease the mechanical bruising.
