摘要: 针对单滚轮法的致命缺陷,提出一种多滚轮多传感器冗余测量方案用于大轴直径的高精度测量.所设计方案采用多滚轮和数据融合技术剔除打滑信号,并对温度、压力变形引起的测量误差进行分离与修正,测量精度显著提高.介绍了滚轮法测量原理和测量系统组成,分析了测量误差.实验表明所设计系统的测量精度小于5μm/m.

关键词: 多滚轮法, 大直径, 数据融合, 误差分离与修正

Abstract: A multi-roller and multi-sensor measurement solution based on the analysis on the intrinsic limitations of the single-roller method is proposed to measure the large diameters accurately.In the measurement system designed, the multiple rollers and data fusion technology are used to eliminate the sliding signals, as well as the separating and correcting the measurement errors aroused by the thermal-deformation and pressure deformation to improve the measurement accuracy of the system observably.In this paper, the measurement principle and system of the roller method are introduced and the measurement errors are analyzed.The experimental results show that the measurement accuracy of designed system exceeds 5 μm/m.

Key words: multi-roller method, large diameter, data fusion, error separating and correcting
