摘要
结合国产 CDP—IIA 型电子皮带秤的机械系统,介绍一种十字弹簧单支承双悬臂多质点梁的线性振动模型,在一般教科书上尚属罕见。其振动研究为电子皮带秤的灵敏性、稳定性和可靠性分析提供了科学依据。
As an example of the mechanical system of the home-madeCDP-ⅡA electronic conveying belting balance,a kind of the linear vibratory model ofthe cantilever beam existing many concentrical masses,which is born in single at themiddle section to used two plate springs meet at right angles is presented.This questionmentioned in the paper is discussed not commonly in the textbooks.This research vibra-ted provides a scientific basis for analysing the sensitivity,stability and reliability of theelectronic belting balance.
