Abstract:
The dynamic nonlinear force versus deformation model of the corrugated board was proposed, and its model parameters were estimated in terms of the dynamics characteristics obtained by dropping compression tests. The cushioning dropping model of the falling apple on the corrugated board was developed. The cushioning dropping tests were conducted on fresh ‘Fuji’ apples at four heights: 10, 20, 30, 50 cm. Then, the dropping impact responses of theoretic model and tests for apples were obtained. Results show that the cushioning dropping model was good agreed with test data, and the corrugated board notably reduced the impact accelerations of apples. The cushioning dropping model provides the foundation of cushioning packaging design for apple fruit.
