摘要
对目前较为常用的钢弦式、应变片式和光电式三种轴功率测量方法进行介绍并分析各自系统误差影响因素,利用变异系数分析法对用以上三种方法测得的实船数据进行分析和比较,并结合三种仪器的安装操作过程和应用前景得出三种方法各自的优缺点。
The commonly used measuring instruments of shaft power include vibratingwire,strain gauge and photoelectric was introduced.And major factors which have influence on degree of accuracy were analyzed.Besides,experimental data measured by variation coefficient for three methods was analyzed and compared.The advantages and disadvantages of the three methods were obtained through the installation operation process and application prospect.
