乌龟壳结构的承力特点研究及应用探讨

Force-bearing characteristics of tortoiseshell structure and exploratory discussion of application

对乌龟壳结构承力特点进行了计算研究,结果表明,在顶部小面积压力载荷作用下,拱形有支撑的龟壳形结构能在保证结构强度的条件下增大内腔容积,这种结构对新型活塞顶部内腔的设计有一定的借鉴意义。

This paper carried out a research of calculation on the force-bearing characteristics of tortoiseshell structure. The result showed that under the effect of compressive loading on a small area of top part, the arch formed tortoiseshell shaped structure with support could increase its volume of inner cavity under the condition of ensuring the strength of structure. This kind of structure has certain referential significance to the de sign of new typed inner cavity of top part of piston.
