基于等强度理论的缩套超高压缸改进设计

Improved Design of Shrunk Super High Pressure Cylinder Based on Equal Strength Theory

根据等强度理论所确定的缩套圆筒的界面压力公式及径比条件,对某超高压缸的径比及应力进行了分析计算,发现其径比不符合径比条件,应力分布也很不均匀。针对该超高压缸所存在的问题进行了改进设计,改进设计后的超高压缸的应力分布比原超高压缸有较大的改善,表明改进设计方案达到了较好的技术效果。

According to the equation of shrunk interface pressure and the condition of diametrical ratio based on the theory of equal strength, it is found that the diametrical ratio does not conform to the condition of diametrical ratio, and the distribution of stress is very non-uniform. According to the problems existed in the super high pressure cylinder, an improved design is accomplished. The improved super high pressure cylinder is much better than original one in distributing of stress, and has a better techni...
