孔的挤胀销棒应力压印工艺
3) pin coining
销棒压印
1.
The paper mainly analysed the new technics method—dowel pin coining technology.
主要分析了在MD90飞机尾段装配过程中的新工艺———销棒压印工艺和要求,以及在有无衬套挤压情况下的使用寿命,论述了通过冷加工方法,在不改变结构件尺寸和不增加重量的前提下,在高应力区对孔壁进行挤胀销棒应力压印,使孔周围材料产生塑性变形,改变应力,并在反复拉伸载荷作用下降低孔边应力峰值,从而提高结构件疲劳寿命。
4) Pressure Bar Top Pin
压力棒上销
1.
Practice of Applying Spinning Pressure Bar Top Pin
细纱压力棒上销的应用实践
5) compressive stress
挤压应力
1.
The authors think that the central paleouplift in the Ordos basin was formed under the nearly E W lateral compressive stress produced by the collision and amalgamation of the Qilian trough and the Ordos basin in early Palaeozoic time.
运用板块构造理论,对鄂尔多斯盆地西缘和南缘的地质背景和构造变形特征进行分析,认为鄂尔多斯盆地中央古隆起在早古生代由祁连海槽与鄂尔多斯盆地碰撞拼贴产生的近东西方向的侧向挤压应力作用而形成。
6) bearing stress
挤压应力
1.
Also a new method on shear stress in beams is advanced and the calculation formula of shear stress and bearing stress of arbitrary variable cross section beams is derived.
提出了梁内剪应力的新证法,并推导出任意变截面梁的剪应力和挤压应力的计算公式。
补充资料:销印
1.销毁印章。《史记.留侯世家》载项羽急围刘邦于荥阳。郦食其谓刘邦曰:莫若复立六国后世﹐铸印以示德义。"德义已行﹐陛下南乡称霸﹐楚必敛衽而朝。"邦曰:"善。趣刻印﹐先生因行佩之矣。"张良闻﹐曰:若立六国﹐则其后世必与汉争霸。"且夫楚唯无强﹐六国立者复桡而从之﹐陛下焉得而臣之?诚用客之谋﹐陛下事去矣"。邦辍食吐哺﹐骂曰:"竖儒﹐几败而公事!"令速销印。
