An ANSYS/LS-DYNA simulation and experimental study of circular saw blade cutting system of mulberry cutting machine

摘要

The paper describes a method of an explicit kinetic simulation and experimental study of circular saw blade cutting system of small mulberry cutting machine. This simulation is based on orthogonal test of numerical simulation. Firstly, main influencing factors and working conditions in the cutting process were considered according to principle of orthogonal test combined with specific working characteristics and material characteristics of circular saw blades. Large-scale CAE software ANSYS/LS-DYNA was used to respectively establish three-dimensional finite element models of the circular saw blade cutting system with different levels of factors. The boundary constraints and loads were given to conduct explicit kinetic analysis and calculation. The corrections processing and post-processing analysis of finite element analytical model was conducted by simulation tests. The Statistics software, Statistical Package for the Social Sciences (SPSS), is used to analyze the simulation analysis calculating results based on analysis of variance (ANOVA), thus to quickly find the best working parameters of circular saw blade cutting system. Experiments were conducted to measure cutting forces and to compare the surface quality of the mulberry branch under different conditions. The cutting force received by the circular saw blade under the optimal parameter matching was relatively small, and the cutting cross-section quality of the mulberry branches tended to be good, and the work efficiency could also be guaranteed.
