摘要

在本文中;介绍了一种张力测量试验系统的设计、标定及测量不确定度分析。该系统设计用于测量拖曳阵列上的张力，该阵列通过电缆拖在水面舰艇后面。为校准过程准备了一个特殊的测试装置，模拟测量系统的静态和动态条件。测量系统的校正使用不同的负载进行，以150公斤的增量从150公斤改变到2500公斤。然后分别对静态和动态条件分别采用曲线拟合程序和缺乏拟合检验进行回归分析。通过计算测试系统的测量不确定度，对测量系统在标定试验中获得的数据进行分析。在静态和动态条件下，确定由校准数据误差、仪器误差和曲线拟合过程引起的标准不确定度。此外，还计算了组合不确定度和展开不确定度，并进行了比较。

Design, calibration and measurement uncertainty analysis of a tension measurement test system

In this article; design, calibration and measurement uncertainty analysis of a tension measurement test system are presented. This system is designed for measuring tension force on a towed array which is towed behind surface ships via a cable. A special test setup that simulates the static and dynamic conditions for the measurement system is prepared for the calibration process. Calibration of the measurement system is carried out using different loads which are changed from 150 kg to 2500 kg by 150 kg increments. Then regression analysis is conducted by applying curve fitting procedure and lack of fit test for static and dynamic conditions separately. Data acquired by the measurement system in the calibration tests are analyzed by calculating measurement uncertainties in the test system. Standard uncertainties due to calibration data errors, instrument errors and curve fitting process are determined for static and dynamic conditions. In addition, combined and expanded uncertainties are calculated and compared to each other.
