摘要

在利用精密分度头测量摆式加速度计的零偏过程中

安装误差是一项主要误差。计算结果表明:若分度头盘面与重力方向之间存在夹角

且摆式加速度计的摆轴与分度头转轴之间存在夹角ψ

则由这2个安装角度误差所引起的零偏测量误差为ψg（其中

g为重力加速度）。这一结果对零偏测量实验中的安装操作具有重要的指导意义。

Abstract

In the zero measurement of the zero bias of pendulous accelerometer with protractor

the main error in the measurement result is caused by the mounting error.The calculation result shows that the angle  between the protractor plate and the gravity and the angle ψ between the pendulous axis of the accelerometer and the protractor axis can cause a measurement error of  ψg

in which g is the free-fall acceleration at earth’s surface.This result is quite important for mounting the pendulous accelerometer in the zero bias measurement experiment.
