1 前言圆筒形和圆柱形负荷传感器是最基本的负荷传感器,广泛地用于测定较大的单轴负荷的场合。在这类传感器中,即使负荷的绝对值都相同,往往因负荷分布状态不同,输出应变也将产生误差。端部设置了法兰的负荷传感器与没有法兰的相比,负荷面积增加,负荷的分布状态将产生更大的变化。因此,带法兰的负荷传感器因负荷状态的变化而产生的误差是决定负荷传感器精度的重要因素。然而,迄今为
1 Introduction Cylindrical and cylindrical load cells are the most basic load cells and are widely used to determine large uniaxial loads. In such sensors, even if the absolute value of the load are the same, often due to different load distribution status, the output strain will also be an error. The flange-mounted load cell at the end increases the load area compared to the non-flanged version, resulting in greater variations in load distribution. Therefore, the flange load sensor load status changes caused by the error is an important factor in determining the accuracy of the load cell. However, so far
