合理地确定多层挤压筒的各参数,是设计中的关键问题。本文引入了预紧系数,建立了较完善的和统一的数字模型,并编制了相应的程序。采用此程序进行优化设计,能适应各种不同的情况,并对多个参数进行调选,使用FELIXC型计算机,约两分钟即可求得目标函数值及全部相应的参数。
Reasonable to determine the parameters of multi-layer extrusion tube is a key issue in the design. In this paper, the pre-tension coefficient is introduced, and a perfect and unified numerical model is established and the corresponding procedures are compiled. Using this program to optimize the design, to adapt to a variety of different situations, and a number of parameters for selection, the use of FELIXC type computer, about two minutes to obtain the objective function value and all the corresponding parameters.
