Revision Suggestions for GB/T 34887-2017 Hydraulic fluid power-Test code for the determination of noise level of hydraulic motors
摘要
Abstract
[Objective]This study proposes revisions to the national standard GB/T 34887-2017,Hydraulic fluid power-Test code for the determination of noise level of hydraulic motors.[Methods]The proposed revisions include:updating terminology and definitions;introducing a cuboid measurement surface test environment;adding supplementary noise measurement points on a hemispherical measurement surface;correcting formulas for A-weighted average sound pressure level and sound power level;updating the permissible system error specifications for measuring instruments;and re-evaluating background noise correction values.[Results]The results show that these revisions address problems such as deficiencies in terminology definitions and ambiguities in data collection methods in the current standard.They broaden the standard's scope of application,enhance measurement accuracy,and improve the reliability and consistency of test results.[Conclusion]The revision of the standard will provide clearer guidance for the design,manufacturing,and application of low-noise hydraulic motors,contributing to the industry's green and sustainable development.关键词
