Determining the Current-Compensation Factor for a High-Current Relativistic Electron Beam in the Presence of an External Liner
      
It was ascertained that fm of the high-current REB slightly varied with the gas pressure and was virtually independent of the resistance of the external liner.
      
The liner-plasma shapes are visualized by detecting the intrinsic liner radiation in various wavelength ranges and actively probing liners in the visible and X-ray regions.
      
The probing of both the liner peripheral and near-axial regions is considered.

The present article sums up the authors' work on the calculation of the stress in the friction wheel of the Koepe multirope hoist by finite element method.A compa- rison of the authors' calculated results represented by the radial flexure curve appea- ring in this article with that well-known calculated data by O.Popowicz of Germany shows that the former agrees closer with the actual situation.The pattern of the stress distribution found in the present work not only responds to the corresponding effect of the bending moments but also responds figuratively to the location of action of the friction lining. As shown by the calculated results,the bending moment and the stress levels for the friction wheel are far below those for the drum of a single-rope hoist.This is because each of the several ropes of the Koepe hoist shares a smaller tension and the friction lining reduces the uniformly distributed load on the friction wheel caused by the ropes.Intermittent action also helps to result in lower loads. In the last part of the article,it is concluded that the strength of the friction wheel is not necessarily the crucial point in designing since the bending moment and stress levels are low.Instead,the authors suggest that a thorough study on the stability of the friction wheel and the residual stress in the welded seams be unfolded.

本文为使用有限元法对摩擦轮进行计算的一个小结。对照表明,所算出的摩擦轮径向挠度曲线图比德国O.Popowicz的著名计算更接近于实际。应力分布规律除反映出相应弯矩的影响外,还形象地反映出摩擦衬垫的作用位置。从计算结果来看,摩擦轮上的弯矩和应力水平,远较单绳提升机卷筒的数值为低。这是由于多绳提升机每根钢丝绳的拉力较小;摩擦衬垫底部较宽使得钢丝绳对摩擦轮的均布载荷变小,并且是间断作用等因素造成的。文章最后认为:摩擦轮的弯矩和应力水平不高,强度问题不是主要矛盾,应开展关于摩擦轮的稳定性和焊缝残余应力的研究。

The following factors which will affect a service life of a liner on a multirope friction hoist are theoretically analysed in this paper:

本文从理论上分析了绳槽半径差△R、钢绳有效长度差△L、衬垫刚度及衬垫材料耐磨性等因素对多绳摩擦提升机衬垫使用寿命的影响。导出了确定衬垫使用寿命的计算式,并通过实例说明,衬垫维护的好坏对其使用寿命的影响是相当大的。当衬垫处于磨合运转状态时,△R及△L的存在对衬垫的最高寿命几乎没有影响。当衬垫处于加剧磨损状态时,衬垫的使用寿命将急剧减小。此外,本文还通过实例说明,若将衬垫简化为刚性体,其使用寿命的计算误差是很大的。因此,衬垫使用寿命的计算应当考虑其本身弹性的影响。

The Paper discusses slip-limit of wire-rope along the lining for friction hoisting including shaft resistance, influence of shaft resistance and principles for selection by using Euler's formula. It gives a definition of dynamic reserve coefficient, and functions of value region, approximate value, safe value, economic value. When the friction coefficient of lining f≥0.228, the most optimal value of economic dynamic reserve coefficient, namely 0.9 can be obtained at all wrap angle. The new viewpoint's on hazardous status and points can be used to check the optimal antislip weight of hoisting Container and the optimal safe-transfering braking force.
