悬臂式电子皮带秤特性分析及降低其失真度的途径

THE ANALYSIS OF CHARACTERISTICS FROM CANTILEVERED BELT-ELECTRONIC WEIGHER AND THE METHOD TO REDUCE ITS DEGREE OF DISTORTION

对悬臂式电子皮带力转换特性进行了分析，从理论上推导了悬臂式秤架的数学模型即传递函数，指出了产生测量失真的主要原因是秤架具有不等灵敏度，从而使其数学模型具有二次积分特性。本文提出了一种等灵敏度秤架的方案，并改善了它的特性。

This paper analyses dynamic characteristic of converting and derives transfer function of cantilevered belt-electronic weigher in theory.Because sensitivity of the cantilevered belt weigher holder is not equal,its.mathemetical model has doudle integral. In order to reduce its degree of distortion.The authors give a equisensitivity weigher holder in the paper to improve its dynamic characteritics.
