Fatigue Damage of a Cutter Used for Cutting Cashew Nut under Random Load

Abstract

To study the fatigue damage of a cutter used for cutting cashew nut, the integrated<br />simulation platform is established with Hypermesh, LS-Dyna, LS-PrePost, and nCode GlyphWorks.<br />The simulation model is established by Hypermesh. LS-Dyna is used to calculate the k file.<br />LS-PrePost is used as the post-processing software. The rain-flow counting, load superposition and<br />extrapolation are executed using Rainflow module in nCode GlyphWorks. The analysis of the<br />fatigue damage of the cutter is executed using Stress Life module in nCode GlyphWorks. The<br />equivalent stress time history of different elements in the upper and lower cutters, rain-flow<br />counting histogram after load spectrum superposition, rain-flow counting histograms after load<br />spectrum extrapolation, and damage histogram of the cutter are obtained. The results show that the<br />cutter has excellent mechanical properties, and the minimum fatigue life of the cutter is about 495<br />days, which is a conservative solution.

“…Cashew (Anacardium Occidentale L.) nut is an important tropical fruit crop that originated from South American countries, such as Bolivia, Brazil, Ecuador and Peru (Aliyu and Awopetu, 2007;Fu et al, 2015). At present, Vietnam is the world's leading exporter of cashew nuts.…”
