Shock and vibration inputs are transmitted from the transporting vehicle through the packaging to the fruit. The vibration causes sustained bouncing of fruits against each other and the container wall. The steady state vibration input may cause serous fruit injury, and the damage is particularly severe if the fruits are bounced at its resonance frequency. The determination of the resonance frequencies of the fruits and vegetables may help the packaging designer to determine the proper packaging system providing adequate protection for the fruits, and to understand the complex interaction between the components of the fruits when they relate to expected transportation vibration inputs. To analyze the vibration properties of the apples for optimum packaging design during transportation, random vibration tests were carried out. In the random vibration test, the resonance frequency and PSD of the packaged freight of apples in the test were in the range of 82 to 97 Hz and 0.0013 to 0.0021G2/Hz respectively and the resonance frequency and PSD of the packaged apples in the test were in the range of 13 to 71 Hz and 0.0143 to 0.0923G2/Hz.
