Foreword

This standard replaces GB/T 11706-1989 "Methods of measurement of marine engine room auxiliaries vibration intensity" and GB/T 16301-1996 "Ship Evaluation auxiliary cabin vibration intensity. " This standard and GB/T 11706-1989, GB/T 16301-1996, compared are the following changes. --- The "measuring gauge" and "evaluation value" expressed in the same chapters, in favor of "vibration severity" expression and understanding. --- In the "Installation conditions" section of the elastic support stiffness and natural frequency of the support frame modal frequencies have quantified requirements. --- In evaluation classification of the device and improve the fan vibration intensity grading. --- In Appendix A, increasing the turbine generator, diesel generator sets arranged recommendation FIG vibration intensity measuring point. Appendix A of this standard is informative annex, Annex B is normative appendix. The standard proposed by China Shipbuilding Industry Corporation. This standard by the National Marine Machinery Standardization Technical Committee on deck and engine room auxiliaries Technical Committee (TC137/SC2) centralized. This standard was drafted. China Shipbuilding Industry Corporation seventh  four Institute. The main drafters of this Standard. Money Network Health, Wang Qiang, Sun Hongjun. This standard replaces the standards previously issued as follows. --- GB/T 11706-1989, GB/T 16301-1996. Auxiliary ship cabin vibration intensity Measurement and Evaluation

1 Scope

This standard specifies the turbine generator, diesel generators, compressors, pumps, fans, refrigerators and motors and other auxiliary ship cabin strong vibration Methods of measurement and evaluation of the degree. This standard applies to the measurement and evaluation of vibration severity limit auxiliary ship cabin under normal operating conditions. This standard is not used to find local oscillator, fault diagnosis, study of local vibration or other research purposes.

2 measuring gauges and evaluation values

2.1 Measurement gauge This standard specifies the rms vibration velocity as the characterization of machine vibration intensity measuring gauge. By the formula (1). Vp rms = 1T∫ Where. --- Vp RMS RMS value of vibration velocity in millimeters per second (mm/s); T --- measurement period in seconds (s). 2.2 Evaluation of the magnitude This standard uses the vibration intensity of the machine as the evaluation of machine vibration magnitude, (2) as defined in the formula. Vp s =  Vp X N () X +  Vp YN () Y +  Vp ZN () Z Sang (2) Where. Vp s --- vibration intensity in millimeters per second (mm/s); Vp X, Vp Y, Z --- Vp are X, Y, vibration velocity Z3 mutually perpendicular directions rms, in millimeters per second (mm/s); NX, NY, NZ --- respectively X, Y, measurement points on the Z3 directions.

3 Measuring Instruments

3.1 Measuring Instruments Systems Vibration intensity measuring system generally consists of sensors, preamplifier, an indicator or recorder, etc., shown in Figure 1. Composition 1 vibration intensity measuring system of FIG. ......
