【摘要】 平面阵精度直接影响天线的电讯特性,为了分析制造过程中的阵面误差,指导工人操作,提高大型平面阵精度,提出平面阵精度统计误差分析方法,推导出各公差带测量点数计算公式,绘制"公差带-统计数"评判图,并运用Excel函数实现了平面阵精度统计误差计算。某大型平面阵制造过程中,运用统计误差,解决了阵面精度分析和调整难题,测试结果表明,天线各项电讯特性均满足设计要求。更多还原

【Abstract】 The plane array precision directly affects antenna electrical characters. In order to analyse the array tolerance, supervise the worker’s operations, and increase the precision of big scale plane array in the processes of manufacturing, proposed the statistical tolerance analysis method of plane array precision, deduced the statistical formula of measure numbers in every tolerance region, drew "tolerance-statistical numbers" evaluation chart, and realized the statistical tolerance compute of plane array precision by using Excel function. In the processes of a big scale plane array, the problems of the array precision analysis and adjustment were solved by using statistical tolerance. The result of tests showed the electrical characters of antenna met the design requirement.更多还原
