摘要
采用ANSYS Workbench软件,对大直径不锈钢棒料剥皮机的刀盘系统进行自由模态分析,并对刀盘系统进行了纵横向加强筋优化,对优化后的刀盘分别进行模态分析和静力学分析。结果表明,优化后的刀盘第7～10阶固有频率相比原始刀盘依次提升了18%,8%,23%,14%,有效优化了原始刀盘结构,增加了刀盘刚度,使刀盘固有频率更加远离剥皮机的工作基频。剥皮机切削Φ320 mm不锈钢棒料的极限工况下最大等效应力为16.3 MPa,最大等效应变值为0.000 1;新型刀盘系统在切削Φ320 mm不锈钢棒料的极限工况下等效应力和应变值均满足工作需求,可为大直径不锈钢棒料剥皮机刀盘系统的设计提供重要的参考依据。
Free modal analysis of cutter system of peeling machine for large diameter stainless steel bar was performed using ANSYS Workbench software,and the cutter system was optimized by adding longitudinal and transverse stiffeners.Modal analysis and static analysis were used for optimizatation of cutter.The results show that compared with the original cutter,7 th^10 th natural frequencies of optimized cutter increase by 18%,8%,23% and 14%,respectively,which optimizes the structure of the original cutter and increases stiffness of the cutter.The natural frequency of the cutter is more deviated from the basic frequency of the peeling machine.Under this ultimate working condition,Φ320 mm stainless steel bar is cut,the maximum equivalent stress of peeling machine is 16.3 MPa,and the maximum equivalent strain is 0.000 1.The equivalent stress and strain values of the new cutter system meet the working requirements under the extreme conditions of cutting Φ320 mm stainless steel bars.It could provide an important reference for the design of cutter structure of peeling for large diameter stainless steel bar.
