In order to improve simulation accuracy,a new method was carried out to model the finite element model by combining solid-shell element with solid element.
编制残余应力施加通用程序,建立包含有初始残余应力的加工变形有限元预测模型;由于铣削加工,毛坯体变为薄壁工件,在进行有限元仿真过程中,提出体-壳单元与实体单元的混合单元建模方法,以提高计算效率及便于后续研究;针对工件与工作台单面约束的接触作用及其它工程中的类似单面约束问题,提出将工件视为弹性体,工作台视为刚性体,转化为接触方式进行纯压缩边界条件的模拟,对某典型工件进行了有限元仿真并与模态试验结果对比,验证了其有效性和准确性;基于生死单元技术进行材料去除模拟。
