摘要

为了解决机匣冲压回弹及焊接变形问题，提出一种机匣内部橡皮囊膨胀校形工艺。以某机匣为研究对象，通过理论计算确定了机匣校形压力。借助有限元分析软件，对与机匣有相同基本特征的薄壁焊接筒形件的塑性变形受力特性及校圆行为进行了分析。模拟结果显示，筒形件的初始直径、跳动和壁厚对最终筒形件跳动校正效果有影响。利用自制的校形装置对橡皮囊胀形法校形效果进行了验证。

Abstract

To solve the springback and welding deformation problem of case shell

a new sizing method based on rubber fluid forming was proposed. Using a casing as the object of study

the pressure of case shell sizing is preliminarily determined by theoretical calculation. The dynamic explicit finite element method is adopted in the plastic deformation mechanism and circular alignment behavior of thin-walled welded cylindrical parts with the same basic characteristics as the casing is analyzed. And the results of finite element analysis show that the initial diameter

runout and wall thickness of the cylinder have influence on the runout orrection effect. The calibration effect of rubber fluid forming method was verified by a self-made calibration device.
