Losses due to damage during transportation of strawberries are estimated at several billion yen per year. We have been studying strawberry packaging from the perspective of reducing transportation damage. All aspects of packaging were studied. Our goal in the development of cushioning for the assembly of individual packages, approached as a series spring problem, was to reduce vibration by 30%. At the cargo level application of dynamic vibration absorber theory enabled development of damping equipment which reduced vibration by 50%. With the use of CAE, I have developed film that is effective against damage by rubbing, as proven during a simulation using a pack of strawberries. This research and development effort was able to achieve results by combining expertise from the University, the Agricultural Experiment Station, and the Industrial Research Institute, as well as joint research with automobile manufacturers. Cross-cooperation between different engineering disciplines is essential for the development of new technology.
