一、引言最近几年,电子秤的使用日趋广泛。而在这些秤中,最普遍使用的传递元件,则是以应变计为转换元件的电阻应变式测力传感器。关于应变计的使用和特点许多文献中已有介绍,这里仅介绍一种“平行梁式传感器”的设计计算和弹性元件的受力分析。二、结构原理和计算 (一)结构型式之一(见图1) 平行梁式传感器是根据应变计的检测原理,当受到载荷作用时,被粘贴在1-4位置的应变计,分别受到拉和压变形,应变计组成 I. Introduction In recent years, the use of electronic scales is becoming more widespread. In these scales, the most commonly used transfer element is a strain gauge strain gauge transducer. On the use and characteristics of strain gauges have been introduced in many literature, here only describes a “parallel beam sensor” design calculations and elastic components of the force analysis. Second, the structure principle and calculation (a) one of the structural type (see Figure 1) parallel beam sensor is based on the detection principle of the strain gauge, when subjected to the role of load, was attached to the 1-4 position of the strain gauge, respectively, by pulling And pressure deformation, strain gauge composition
