摘要: 在空間解析曲面模型理論基礎(chǔ)上,采用三維彈塑性大變形有限元方法,建立了復(fù)雜幾何形體動態(tài)約束模型,解決了張力減徑過程中的矩陣變換、模型轉(zhuǎn)換和多機架全系統(tǒng)仿真的問題。Abstract: Based on the theory of space analysis curved surface model, a complex geometric dynamic captive model is set up by means of the FE method of three-dimensional elastic-plastic large deformation, which leads to the solution of issues concerning the stretch reducing process such as matrixing, model conversion and simulation of the multi-stand system as a whole.
