海产品生产企业多采用鱿鱼切割机以实现鱿鱼头部与身体的分离.刀具几何参数不合理,易出现切割鱿鱼连肉现象,影响切割质量.文章采用拉伸破坏实验得到鱿鱼肌肉相关力学参数,利用ABAQUS建立鱿鱼切割过程模型并进行有限元分析,获取各方案刀具的受力云图及动能、应变能的变化曲线,再结合鱿鱼切割实验结果,对切割机刀具进行分析,从而确定刀具的最佳几何参数方案.综合分析可知,下刀面倾角为50° ~60°且带有锯齿的刀具动能、应变能较大,有利于实际作业中机器对鱿鱼体的切割.该刀具可以提高鱿鱼切割质量和效率,降低劳动力投入,为海产品生产企业的产业结构升级提供有力帮助.%Nowadays seafood producers mainly use squid cutting machine to realize the separation of squid head and body. If the geometric parameters of cutter are unreasonable, the sticking phenomenon between cutter and squid would happen and influence the cutting quality. The paper conducted tensile failure test to get the relevant mechanical parameters of squid muscle. ABAQUS was utilized to establish the model of squid cutting process. Based on the model, the finite element analysis was performed and the stress nephograms kinetic, and strain energy curves of each scheme were obtained. Combined with the results of squid cutting experiment, the cutters would be analyzed to determine the optimal geometric parameter scheme. The comprehensive analysis shows that cutters whose dip angle of lower blade be-tween 50°~60° and that had sawtooth have larger kinetic and strain energy,which is in favor of cutting squid body by machine in the actual operation. The chosen cutter could improve the quality and efficiency of squid cutting, and re-duce the labor input.We wish these results can provide valuable reference for the industrial structure upgrading of sea-food producers.
