查询词典 friction coefficient

The tests showed that the tension of each hoop cable and radial cable distributed unevenly under various working conditions,because of the friction between hoop cable and joints.Compared with the traditional joints,using new joints in structure could make the friction between hoop cable and joints reduce obviously,and friction loss on hoop cable at joints was small.

试验表明，由于环索与节点间存在摩擦，使得各工况下结构各圈环索和斜索张力分布不均匀；与传统节点相比，采用新型节点的结构环索与节点间的摩擦大幅降低，环索预应力损失较小，预应力传递效率更高。

The needle would stop rolling to maintain the friction effect between the needle and tested tissue when this friction moment come to the driving moment of the friction coupler.

二、在驱动电机和刺激针之间设计一个摩擦耦合器，当刺激针和组织之间的摩擦力矩达到摩擦耦合器的驱动力矩后，刺激针就会停止转动并能保持住对组织的摩擦。

Experimental results show that: bearing capacity of JPP is thirty percent higher than that of cast-in-place pile which has the same length and diameter with JPP. The deformation of JPP is controlled by core pile; axial force distribution of PHC is different with soil-cement; and their axial force ratio in same section is their elastic modulus ratio. Distribution of inner and outer friction resistance is similar; and the inner friction is about 1.62 times of the outer one; it is about the ratio of JPP diameter and PHC diameter. Furthermore, the relation between friction resistance and relative displacement is similarly hyperbolic; and the relation between dip resistance and displacement is also hyperbolic.

试验结果表明，JPP桩与同桩长、同桩经灌注桩相比承载力高30%以上；JPP桩变形由芯桩控制，管桩轴力分布与水泥土轴力分布规律不一致，但同一截面上管桩和水泥土的轴力比值约为其弹性模量的比值；内外摩阻沿桩身的分布规律类似，内摩阻是外摩阻的1.62倍左右，约为JPP桩直径和管桩直径的比值；桩侧摩阻力与桩土相对位移近似双曲线分布，桩端阻力和桩端位移也近似双曲线分布。

Scene data indicate that in the process of actual making the casing into the Horizontal Well ,people used to reduce friction coefficient between the stratum and the Casing, Change the friction type between the casing and the wall,use special casing and centralizer with oriented ring, even join the slurry in the internal casing in order to increase self-casing, etc.

现场资料表明，在实际套管下入过程中，人们往往采用的是减小套管与井壁之间的摩擦系数、改变套管与井壁间的摩擦类型，使用带有导向环的套管和扶正器，甚至在套管内部加入泥浆，以增加套管自重等方法，但这些方法并没有改变套管下入驱动力减少的现实，不能从根本上解决套管下入困难的问题。

My main production TSF Academy Soft Machine Tool belt and matching adhesive used primarily for machine tool guideways, abrasion resistance, static and dynamic friction coefficient of the difference small, not crawling, positioning accuracy, and has enough anti-aging and physical properties of mechanical is to improve the machining precision, extended service life Guide the best choice, the products applicable to all types of machinery and equipment manufacturing friction vice and maintenance.
