An Approach to Reduce Cargo Damage

To understand relationship between vibration on cargo bay of truck and bruise of strawberries in long transportation, a detail analysis of a strawberry-transport was carried out. Vibration in various locations on the truck box was measured throughout the route, and increase of damage to the strawberries was observed at the end of the journey. Also, S-N diagram of strawberries in various frequencies was measured in shaker tests. From these data, a “degree of damage” which can assess the occurrence of bruise was established.
