【摘要】 介绍了一种用于冷弯型钢、焊管辊型设计过程的交互式计算机辅助设计系统CRF-CAD,该系统是在分析了冷弯成形过程特点及设计人员设计思维过程的基础上,以实验数据为依据而建立的。在计算及绘图过程中,系统采用人机交互式作业方式,并具有辊型设计、变形模拟、优化分配变形、绘制冷弯变形图及辊型工程图等多种功能。本系统包括完全取决于实际设计经验数据的检索型方式和经验数据、实验与成形理论、优化方法相结合的解析型方式。本文着重介绍了后者。更多还原

【Abstract】 This paper describes a new interactive computer-aided design system for roll forming (CRFCAD). It is based upon analyzing the forming process, the thinking process of designer, and the experimental results. It is multifunctional, in which roll design, simulation, optimization and drawing are involved. By the interaction between the operator and computer, the reproducibility can be easily obtained.The system includes searching method which is wholly depended upon the design data of successful experience and analytical method, which combines the production data, theory of plastic working and its experiment data, and optimization. The later is discussed in details in the paper.更多还原
