三维测力仪过去是三个方向输出信号,使用前分别加载标定。标定时很难达到较高的标定精度,而且很费时间。本文介绍的“多功能三维测力仪静标定装置”可对三维测力仪三个方向的输出信号同时进行标定。作者介绍了该装置的结构、工作原理,精度分析及其多功能的特点。 Three-dimensional dynamometer in the past is the output signal in three directions, respectively, before loading calibration. Calibration is difficult to achieve high calibration accuracy, but also time-consuming. This article describes the “multi-function three-dimensional dynamometer static calibration device” can be three-dimensional dynamometer output signals in three directions simultaneously calibrated. The author introduces the structure of the device, working principle, accuracy analysis and its multi-functional characteristics.
