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