| | In order to meet highter requirements for roundness and smoothness of stranded conductors, measures must be taken to eliminate machinecaused scratch and deformation of stranded conductors. The scratch and deformation caused by single capstan tube strander was investigated and the traction system was improved accordingly.As a result, good quality of products has been obtained. | | 因对产品质量提出了更高要求,要求绞线的线芯表面有更高圆整度和光滑度,所以必须克服由设备缺陷引起的线芯表面刮伤和挤压变形等产品的缺陷,对单牵引管式绞线机牵引轮上绞线被挤伤、刮伤等现象进行初探,并对其牵引方式也进行了改进,取得了良好的效果。 | | 文摘来源 | | The measurement method and design thought of the lateral rigidity of the single traction rod device are described. The high speed passenger car dynamics model with 35 degrees of freedom is applied to study the effect of lateral rigidity of the single traction rod device on the dynamics performance of passenger cars. The study shows that the lateral rigidity of the single traction rod shall be reduced as much as possible in order to obtain the good dynamics performance of passenger cars. | | 介绍了单牵引拉杆装置横向刚度的测定方法和设计思路。应用 35个自由度的高速客车动力学模型研究了单牵引拉杆装置横向刚度对客车动力学性能的影响。研究提出 ,为使客车获得良好的动力学性能要尽量减小单牵引拉杆装置的横向刚度 | | 文摘来源 | | The geometry distortion will be compared between SS_7 "Z" shaped traction perch and single traction one as taken into the middle bogie. Its resultis that both distortions are similar basically as locomotive negotiating radius curve of 125m. It is feasible that single traction perch of simple structure will be taken. | | 首次对中间转向架采用SS7型电力机车"Z"字形牵引杆装置及单牵引杆装置的几何变形进行了比较,结果表明机车通过125m半径曲线时,两者的变形基本相当,从而说明可采用结构简单的单牵引杆装置。 | | 文摘来源 | |   | | << 更多相关文摘 |
