外径检测设备使用过程中的误差分析

The Error Analysis in the Process of Od Measuring Devices in Use

结合某外径检测设备的结构特点,建立了该设备的误差分析模型,分析了该设备的误差变化规律,通过算例验证了该误差计算方法;据此给出了影响该设备的误差因素,对全面分析外径检测数据具有重要意义。

Combined with a structural characteristics of od measuring equipment, the error analysis of model of the device is established. The errors of the device tion method for the error is further verified great significance on outer diameter of ~ Thus the effect a comprehensive changes is analyzed. By example, the calcula- of error factor of the device is given. It is of analysis of test data.
