Simulation and Experiment of Mechanical Properties of Potato Compression

Abstract:

Potato sizes of the longshu 3, new daping and zhuangshu 3 proceed statistics, the typical value of potato size statistics is got. Application of section modeling technology gets the potato contour data, then the data imports into Solidworks software and generates Potato solid model, application of ANSYS/Ls-dyna software to carry on the research of potato with a certain rate in X, Y, Z three directions of loading stress. The results show that Potato X finite element model to compression stress was 1.27MPa, Y to the maximum stress is 5.84MPa; Z to the maximum stress is 3.9MPa. The tuber compression test finds that the 35mm/min rate in three different loading directions on potato compression force-time curves are different, Y curve is higher than that of X and Z direction, Z curve is higher than the Z, the rupture force Z is more than X and Y direction, X is higher than Y direction, the simulation curves are basically identical to experimental curves.
