- 摘要:
- 文章根据误差传播理论,对导管架质量控制点本身的精度进行探讨,并由导管架制造完工尺寸公差要求,导出控制点应达到的精度指标。在对质量控制点的点位方差进行深入研究的基础上,给出表示导管架质量控制点在任意方向上精度的绝对误差椭圆和相对误差椭圆,进而将这两种误差椭圆应用于导管架的质量控制中,从而使导管架的质量控制更有效和准确。
On the basis of error propagation theory the precision of quality control points of jacket is studied and the precision specifications are derived from general dimensional tolerance in jacket fabrication. Based on a thorough investigation on positional variances of quality control points of jacket absolute error ellipse and relative error ellipse which can show the precision of quality control points of jacket in any direction are presented and then applied to quality control of jacket.2005,2(2): 32-34 收稿日期:2004-5-11分类号:TE973.1作者简介:徐慧(1957-),女,安徽安庆人,副教授,在天津大学海洋船舶工程系从事科研工作.参考文献:
