摘要

利用材料力学中的力线平移定理并结合有限元方法

综合分析了扁挤压筒优化设计中孔型、层间过盈量、层厚等结构优化参数对扁挤压筒应力分布的影响; 提出了一种扁挤压筒内应力分布优化的新方法

可应用于一般扁挤压筒的设计; 通过分析扁挤压筒的内应力分布情况

提出了一种应力释放扁挤压筒新结构。通过有限元模拟分析验证

得到了较为合理的扁挤压筒新结构的外套宽度和层间过盈量

可使扁挤压筒应力峰值降低5%以上

从而可提高扁挤压筒的使用寿命。此项研究可为优化扁挤压筒结构及装配提供参考。

Abstract

Based on force line translation theorem and finite element method

the stress distribution in the internal surface of flat container was studied

and a new flat container structure was proposed to release its stress concentration. The reasonable width and interference of the new structure were obtained with a suppression of the stress peaks by 5%

so the new structure of flat container can improve its service life. The proposed flat container may provide a reference for optimizing the structure design and assembling of flat containers.
