Abstract

A mathematical model of bruising in impacted multilayered single columns of apples was developed and tested. The model is based on relationships between energy absorbed and bruise volume and calculates the amount of energy absorbed at each interface in the column from energy and momentum considerations using an interactive procedure on a digital computer. The model quantifies the road profile in terms of potholes and bumps and the effects of soft and hard suspensions. A special rig was designed and constructed to test the theoretical model. Over a limited, but representative range of test conditions, good agreement was found between total bruising and bruise distribution predicted by the model and experimental results. The model successfully predicted that bumps caused more bruising than potholes and that soft suspensions reduced bruising relative to hard suspensions
