一、前言对于一定物理现象的模拟,数学模型的计算在过去遇到了几乎是难以克服的困难,主要是在微分方程式的解答中。近来大型计算机的广泛应用就有可能通过方程式的数字途径来解答,否则不能完全精确地分解;计算机的应用还能较快地进行运算。英诺琴提公司在限动芯棒连续轧机的设计中,在有关工艺的深入研究中,大量使用了这些模型。这些模型在有规律的工业性试验基础上进行了修改,使之完善。 I. INTRODUCTION For the simulation of certain physical phenomena, the calculation of mathematical models has encountered almost insurmountable difficulties in the past, mainly in the solution of differential equations. Recently, it has been possible to solve large-scale applications of computers by digital means of equations, otherwise they can not be decomposed with complete precision. Applications of computers can also be operated relatively quickly. Innocenti’s extensive use of these models in the design of the mandrel-bar continuous rolling mill has been extensively studied in the art. These models were modified on the basis of regular industrial tests to make them perfect.
