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