航空发动机加力总管的进油管结构较为特殊,发动机导管成形时由于受设计结构、材料等因素影响,常常产生难以成形、加工质量较差等问题。本文以某型发动机加力燃油总管的进油管为例,借助专业金属板料成形的有限元模拟分析软件PAM-STAMP,对其弯曲成形过程进行数值模拟分析,对软件计算得到的成形结果进行分析,为实际加工工艺的制定和模具的设计提供了重要指导。
The structure of the inlet pipe of aero-engine afterburner is rather special. Due to the influence of design structure, materials and other factors, the formation of the engine pipe often causes problems such as difficulty in forming and poor processing quality. In this paper, an engine fuel filler pipe into the fuel pipe as an example, with the help of professional sheet metal forming finite element simulation software PAM-STAMP, the bending process of numerical simulation analysis of the software to calculate the results of the formation of the analysis , For the actual processing technology and mold design provides an important guide.
