Introduction

JJF 1001-2011 "General Measurement Terms and Definitions", JJF 1071-2010 "Compilation of National Measurement Calibration Specifications" Rules" and JJF 1059:1-2012 "Evaluation and Expression of Measurement Uncertainty" jointly form the basis for formulating this specification Series specifications: This specification specifies the technical specifications for the calibration of angular acceleration tables for inertial technology: The main reference for the writing process of this specification JJF 1210-2008 "Low-speed turntable calibration specifications": This specification is released for the first time: Calibration specifications for low-frequency angular accelerometers

1 Scope

This specification specifies the calibration items and calibration methods of low-frequency angular acceleration tables, and is applicable to standard grating-based Absolute method calibration of low-frequency angular acceleration table below 30Hz:

2 cited documents

This specification references the following documents: JJF 1210-2008 Low-speed turntable calibration specifications JJF 1675-2017 Inertial technical measurement terms and definitions For dated references, only the dated version applies to this specification; for undated references, only the dated edition applies: The latest version (including all modification orders) shall apply to this specification:

3 terms

The terms, definitions and symbols defined in JJF 1675-2017 and the following are applicable to this specification: 3:1 Fluctuationratio The relative maximum rate of change of the measured value within a certain time range: based on a set of measurements being measured over a time range The measured values xi (i=1,2,,n) at equal intervals have a fluctuation rate of Sx= xmax-xmin 2x ×100% In the formula: xmax---the maximum value of the measured xi; xmin---the minimum value of the measured xi; x ---The average value of the measured xi:

4 Overview

The low-frequency angular acceleration platform is mainly composed of mechanical system, control system, measurement system and signal processing system: it can By performing reciprocating motion in forward and reverse directions around the central axis at a certain angular position within a certain angular range, a standard angle can be produced: Displacement, angular velocity and angular acceleration: Can be used for angular acceleration characteristics of inertial devices such as angular accelerometers and gyroscopes calibration:

5 Metering characteristics

The measurement characteristics of the low-frequency angular acceleration table are shown in Table 1:
