1) pre-tension method
预拉力法
1.
This paper describes in details the principle, the operation and the experience for modifying the down deflection of a fixed-girder for bucket wheel stacker/reclaimer and keeping its pre-designed up deflection by means of firing and pre-tension method.
详细介绍用火焰法和预拉力法矫正斗轮机固定梁下挠并保持其拱度的原理、操作方法及经验教训。
2) prestre ss reinforcement method
预应力拉筋法
3) pre-tensioning
先张法;预加拉力
4) pretension controlling method
预拉力控制方法
1.
Therefore,friction-typed high-strength bolt connection anti-sliding coefficient was studied on the side of shot peening mode,resting period and pretension controlling method with 5 series specimens(25 sets).
对5组(25套)摩擦型高强度螺栓试件从喷丸方式、存放时间以及预拉力控制方法等方面对抗滑移系数进行相关的试验研究,发现正面喷丸除锈方式比常规喷丸方式更具优越性;随试件存放时间增加,抗滑移系数也有一定的提高;利用在螺杆上粘贴应变片来控制预拉力方式测定抗滑移系数的可靠性高于轴力计控制预拉力方式。
5) high prestress
高预拉力
6) pretension
