The paper analyzed the reason of twisting for overhead conductor and the relations between conductor wave and rigidity, put forward the test method of twisting moment based on the needs of project and investigation of foreign condition, and discussed the R&D of the special equipment for twisting moment test, still put forward the specific me.
文章分析了架空导线产生扭转的原因以及导线舞动与扭转刚度之间的关系,在对工程需要及国外情况进行调研的基础上提出了扭力矩试验方法,并对扭力矩试验的专用设备的研制进行了探讨和实践,还提出了扭力矩试验参数应用于分裂导线扭转失稳控制的具体方法。
The mechanical properties of notch bolt are tested under MoS2 dry-film lubrication and aviation lubricating-oil under pretightening force when we have brought torque to bear on notch bolt .
对MoS2干膜润滑和航空润滑油润滑的凹口螺栓进行了施加扭力时的预紧力测试,试验结果表明:施加相同扭力时MoS2干膜润滑凹口螺栓较航空润滑油润滑凹口螺栓的预紧力大,亦拧紧螺栓时施加较小的力矩可获得较大的预紧力,这是很有工程价值的现象。
