结合中频热推弯管自动控制成形过程,介绍一种研究工件大变形过程的实验分析方法。该方法不仅可以分析工件的受力、变形特点,而且可以描述工件变形过程瞬时应力、应变状态及其演化过程。为工艺或结构设计提供理论依据。
Combined with the automatic control of forming process by intermediate frequency hot-bend pipe, an experimental analysis method for studying the large deformation process of work piece is introduced. The method can not only analyze the force and deformation characteristics of the workpiece, but also describe the instantaneous stress and strain state and its evolution during the workpiece deformation. For the process or structure design to provide a theoretical basis.
