Background

A deep understanding of the motion and the intensities of forces endured by the fruits overtime during the various handling processes is necessary if improvements are to be made in the handling systems or related tools. The finite element method (FEM) has been used to investigate the effect of mechanical loading on fruit before developing a prototype of the intended design. Simulation tests were performed to visualise the time-dependent deformation behaviour. Various studies have been reported on the use of FE for studying the effect of compression and drop forces on fruits. However, to the best of the knowledge of the authors, the application of finite-element analysis in fruit mechanics has not been summarized yet.

Scope and approach

This review is concerned with establishing the introductory concept of FEM for evaluating fruit response under the static and dynamic loading. The FE equations were formulated based on the stress-strain constitutive equations.

Key findings and conclusions

The review summarises the application of FEM for fruit stress-strain analysis. A brief description of the fundamentals and the existing models that have been developed to cope with problems of fruit mechanics are reported. This paper provides a review of the main FEM studies and a comparison between different types of stress analysis as well as outlining the potential use of FEM for future reference. This review can become an appropriate, timely and beneficial reference for any relevant follow-up research for the assessment of the quality of agricultural produces.

水果应力分析的有限元建模-综述

背景

如果要改进装卸系统或相关工具,则必须对各种装卸过程中水果加班所承受的运动和力量的强度有深刻的了解。在开发预期设计的原型之前,已使用有限元方法(FEM)来研究机械负载对水果的影响。进行了模拟测试以可视化随时间变化的变形行为。关于使用FE来研究压紧力和跌落力对水果的影响的各种研究已有报道。然而,据作者所知,有限元分析在水果力学中的应用尚未被总结。

范围和方法

这项审查是有关建立有限元的入门概念,以评估在静态和动态负荷下的水果反应。有限元方程是基于应力-应变本构方程制定的。

主要发现和结论

综述总结了有限元法在水果应力-应变分析中的应用。报告了为解决水果力学问题而开发的基本原理和现有模型的简要说明。本文概述了主要的有限元分析,并对不同类型的应力分析进行了比较,并概述了有限元的潜在用途,以供将来参考。对于任何有关农产品质量评估的后续研究,此审查都可以成为适当,及时和有益的参考。
