Analysis and evaluation of a fruit bin for apples

Area of Science:

• Agricultural Engineering
• Material Science
• Physics

Background:

• Fruit bins are crucial for apple harvesting, storage, and transport.
• Accurate prediction of bin wall behavior requires understanding lateral pressure distribution by apples.
• Existing models lack detailed insights into static load distribution within fruit bins.

Purpose of the Study:

• To experimentally measure and computationally model the lateral pressure distribution of apples in a fruit bin.
• To analyze the influence of apple unit weight and angle of repose on load distribution.
• To develop a finite element model for predicting fruit bin deformation.

Main Methods:

• Experimental measurement of bin base and wall deflections under apple load.
• Finite element method (FEM) modeling to simulate static load distribution.
• Mathematical modeling to validate lateral pressure distribution on bin walls and base.

Main Results:

• Angle of repose was identified as a significant factor influencing lateral pressure on bin walls.
• A nonlinear lateral pressure distribution was observed along the depth of the bin.
• The finite element model enables comparison of deformation behavior across different bin materials.

Conclusions:

• The study provides a validated model for lateral pressure distribution in apple bins.
• Findings are applicable to other fruits and vegetables with similar unit weight and angle of repose.
• The developed model aids in optimizing fruit bin design for enhanced structural integrity and material selection.
