海洋工程高强度结构钢管卷制成形过程回弹分析

Springback Analysis of Steel Pipe Rolling Formation of High-Strength Structurein Ocean Engineering

板材在卷制成形过程中的回弹现象是影响钢管卷制成形精度的重要因素。文中通过对三辊卷板机加工板材过程中的板材回弹过程进行分析,并建立板材卷制模型进行分布,从而预测卷制成形尺寸,确定板材回弹规律,以提高海洋工程高强度结构钢管卷制成形质量,具有一定的工程实践指导意义。

The springback phenomenon of the plate during the rolling formation process is an important factor affecting the forming accuracy of the steel pipe roll.This paper analyzes the rebound process of the sheet during the processing of the sheet by the three-roller bending machine,and establishes a sheet rolling model for distribution,so as to predict the size of rolling formation,determine the springback law od steel plate,and improve the high-strength structure of ocean engineering.The forming quality of steel pipe roll has certain significance for engineering practice.
