本文介绍了振动供料器固有频率的一种计算方法。振动料斗弹簧变形很复杂,其参数的准确计算是困难的。因此,在一些假定条件下提出了一种近似计算法,阐明了弹簧常数与安装方式之间的关系,并以各种图表形式反映了这种关系。本文还列出了对固定式、半浮动式供料器固有频率简化计算的公式,并讨论了料斗的振动方向。各种理论计算均为实验结果所证实。图10幅。
This article describes a method of calculating the natural frequency of a vibrating feeder. Vibration hopper spring deformation is very complicated, the accurate calculation of the parameters is difficult. Therefore, an approximate calculation method is proposed under some assumptions, clarifying the relationship between the spring constant and the mounting method, and reflecting this relationship in various charts. This paper also lists the simplified formulas for the natural frequencies of fixed and semi-floating feeders, and discusses the vibration direction of the hopper. Various theoretical calculations are confirmed by the experimental results. Figure 10.
