To choose the point elasticity or the arc elasticity? 选择点弹性还是弧弹性?
A model for precisely calculating the flattening contact arc length has been derived using Hertz formula on the basis of the elasticity contact theory. In the model both the roll elastic deformation and the strip elastic deformation have been taken into full consideration. 以弹性接触理论为基础,利用Hertz基本公式,同时考虑轧辊的弹性压扁变形和轧件的弹性回复变形,推导出一个精确计算压扁接触弧长的模型。
At present, the arc contacts in SFe switches is formed by the excellent property of electrical arc resistance of Cu W alloy and the eminent conductivity together with high elasticity of CrCu alloy, so-called CuW/ CrCu integrated contact. 目前在SF6断路器中普遍使用的触头材料一般由耐电弧烧损的CuW部分和提供弹性和导电性的CrCu部分组成,即CuW/CrCu整体触头。
By the analysis of slide and static arc in the elasticity of belt, in this paper was given a better formula to calculate slide rate. The formula provides a exact calculating method for designing belt drives when slide rate is considered. 通过分析带传动弹性滑动中产生静弧和滑动弧的原因,得出了带传动滑动率计算的最优公式,为需要考虑滑动率时的带传动设计提供了一种精确的计算方法。
The paper analyzes the calculation and puts forword an arc elasticity formula to direct product pricing. 本文对其进行了分析,并提出应使用弧弹性公式指导产品定价。
As seen from generator's external characteristic curve, the power factor can be raised by improving the 3rd welding dynamic characterstics, to improve arc elasticity and reduce the deviant of welding current. 由弧焊发电机外特性曲线可知,改善第Ⅲ档的焊接动态特性,可以增加电弧弹性,使得焊接电流的偏移量减小,从而提高了功率因数。
