Introduction

This procedure is revised in accordance with JJF1002-2010 "Rules for the preparation of national metrological verification procedures". This procedure replaces JJG 638-1990 "hydraulic vibration test bed". Compared with JJG 638-1990, in addition to editorial changes, the main technical changes are as follows. --- increased the introduction; --- Added reference documents (see 2); --- increase the hydraulic vibration test system structure diagram (see Figure 1); --- increase the vibration controller, random vibration measurement performance requirements and test methods (see 4.1,4.3); - the measurement of the frequency stability of the measurement requirements and verification methods; - harmonized indicators of vibration amplitude indication error (see 4.2.1); A "dynamic signal analyzer" has been added to the test equipment (see 6.1.2.1); --- modified the "lateral vibration ratio" of the test equipment (see 6.1.2.3); --- "Level recorder" and "digital frequency meter" are removed from the verification equipment; - the addition of the "Verification Project" (see 6.2); --- In accordance with ISO TC108/SC6 Resolution on ISO 8626. 1989 "Horizontal Movement Ratio" The calculation formula of the transverse vibration ratio (6.3.11); - "Appendix 1 check item selection", "Appendix 2 verification result record format" is deleted; - Added "Verification certificate page format" (see Appendix A); --- Added "Verification result page format" (see Appendix B). The previous version of the procedures issued. --- JJG 638-1990. Test procedure for hydraulic vibration test system

3 Overview

Hydraulic vibration test system (hereinafter referred to as vibration test system) is used to produce sinusoidal vibration, random vibration, etc. A complete set of equipment for the vibration test of the test piece in advance. It is usually by the vibration controller, Servo control device, hydraulic vibration generator, hydraulic source, control sensor (accelerometer or displacement meter) and ancillary equipment And other components, as shown in Figure 1. Figure 1 hydraulic vibration test system structure diagram

4 Measurement performance requirements

4.1 vibration controller 4.1.1 Frequency indication error Vibration controller in the specified frequency range, the frequency indication error in line with the provisions of Table 1.
