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。
The force conversion characteristics of cantilever electronic belt are analyzed, and the mathematical model of cantilever scale is deduced theoretically as the transfer function. It is pointed out that the main reason of measurement distortion is that scale platform has unequal sensitivity, so that its mathematical model has Second integral characteristic. This paper presents a scheme of equal sensitivity scale and improves its characteristics.
