管径比,pipe diameter ratio

1)pipe diameter ratio管径比

1.It has analyzed the geometric body factors ofpipe diameter ratio k or K to influence of the bimetal performance.提出了双层管线形复合条件,内外管材料弹性模量接近的条件下,只要满足条件σ_(so)＞σ_(si),即可实现复合;分析了几何结构因素管径比k和K对双层管的影响,分析表明胀合压力存在极值,胀合压力区间随k的增加而迅速扩大,但K越大,胀合压力区间越小;K和k对最小胀合压力和最大胀合压力的影响力是不同的;在相同胀合压力作用下,残余接触压力随管径比k的增加而迅速降低;在最大胀合压力条件下,残余接触压力随管径比k和K增大而增加;对胀合装置进行了改进研究,采用刚性传动与柔性传动相结合的方式,同时还对胀合装置关键部件主轴进行了改良设计,得到了较好的应用效果;分析了温度双层管结合强度的变化,给出了双层管分层松脱机理。
