在1957年第3期“有色金屬”上,发表了以“关于振动粉磨的初步研究”一文。在这篇文章中我認为有几个公式是不正确的,因此提出來商討,并供設計部門和工厂参考。一、該文中,引用了如下公式: a=P_o/∑K 公尺 (1) 式中a—振动磨机体的振幅(公尺)。∑K—支承彈簧的刚度(公斤/公尺)。 P_o—軸上偏心質量产生的慣性力,該力可由下式求得: P_o=∑m_oω~2ρ=ΣG_o/g(π_n/30)~2ρ=ΣGon~2ρ/900公斤 (2)式中Σm_o为軸上偏心質量的总和;ΣG_o为其
In 1957, No. 3 “non-ferrous metals”, published a “preliminary study on vibration grinding” article. In this article I think several formulas are incorrect and are therefore proposed for discussion and for reference by the design department and the factory. First, the article quoted the following formula: a = P_o / ΣK meters (1) where a-vibration mill body amplitude (meters). ΣK-Stiffness of supporting spring (kg / m). P_o-axis eccentric mass generated by the inertial force, the force can be obtained by the following formula: P_o = Σm_oω ~ 2ρ = ΣG_o / g (π_n / 30) ~ 2ρ = ΣGon ~ 2ρ / 900kg (2) where Σm_o is The sum of the eccentric mass on the shaft; ΣG_o is the sum
