本文是基于几何、物理综合互换的原理来控制仪表的总误差,以达到仪表所需要的精度。而仪表的总误差,又是由各个元件的各种原始误差所引起;这些原始误差,主要的有:方法误差、生产误差、温度误差、摩擦误差、迟滞误差、间隙误差等,同时还提出了这些原始误差的求法(计算、实验、测试),并根据极大极小和概率理论导出了误差分配的基本公式和原则。最后还举有实例,以作误差计算分配、布置时的参考。
This article is based on the geometry, the principle of physical integrated exchange to control the total error of the instrument, in order to achieve the required accuracy of the instrument. The total error of the instrument, but also by the various components of the original error caused by these; the original error, the main are: method error, production error, temperature error, friction error, hysteresis error, gap error, etc., also proposed The primitive error of the calculation (calculation, experiment, test), and according to the maximum and minimum probability theory derived error distribution of the basic formulas and principles. Finally, cite examples to make error distribution calculation, layout reference.
