一、前言钢丝缠绕预应力机架是瑞典ASEA公司框架式绕丝高压容器的组成部分,它与传统的三梁四柱式和叠板式压机比较,具有结构紧凑、节约钢材、其关键零件立柱在预压缩应力下工作、安全可靠、疲劳寿命长等一系列独特的优点,因而近几年在我国得到发展。 I. INTRODUCTION The wire-wound prestressing frame is an integral part of ASEA’s frame-wound wire pressure vessel in Sweden. Compared with the traditional three-beam four-column and stacked plate press, it has the advantages of compact structure and saving steel, and the key components of the column are in Pre-compression stress, safe, reliable, long fatigue life and a series of unique advantages, which in recent years has been developed in our country.
