Foreword
This standard is GB 10398-1989 "small gasoline engine vibration test methods" and GB 10399-1989 "Small Gasoline Engine Vibration
Dynamic rating of "amendments.
This standard and GB/T 10398-1989 and GB/T 10399-1989 compared to the main content amended as follows.
--- This standard applies to ignite the following single-cylinder power 12kW single cylinder reciprocating piston type small gasoline engine and the use of alternative fuels
internal combustion engine;
--- Simplify the original standard measuring instrument system requirements;
--- Redefine the validity of a reference standard, and added two criteria;
--- Cancel vibration quality assessment;
--- Calculated on the equivalent vibration intensity, increase the gasoline engine vibration intensity calculation method of the vertical axis.
Since the implementation of this standard replaces GB/T 10398-1989 and GB/T 10399-1989.
Appendix A of this standard is a normative appendix, Appendix B, Appendix C, Appendix D is an informative annex.
This standard is proposed and managed by China Machinery Industry Federation.
This standard was drafted. Tianjin Internal Combustion Engine Research Institute.
The main drafters of this standard. King Yabing, Jia Bin, Yang Jingling, Wang Dong, Sun Yaqin.
This standard replaces the standards previously issued as follows.
--- GB/T 10398-1989;
--- GB/T 10399-1989.
Small gasoline engine vibration test methods and rating
1 Scope
This standard specifies the test method for small gasoline engine vibration and vibration quality rating.
This standard applies to operating speed range 600r/min ~ 14000r/min, 12kW power following a small single cylinder reciprocating piston type steam
Oil machine.
This standard also applies to the power of 12kW or less use of alternative fuels for spark ignition internal combustion engine is a single cylinder.

3 Terms and definitions
Terms and definitions GB/T 2298 established apply to this standard.
3.1
Description gasoline engine - an integrated flat system characteristic parameter vibrational state. With rms vibration velocity as a measure of gasoline flat
The amount of plate system vibration intensity standard.
a) according to the survey record vibration velocity versus time history, vp rms vibration intensity shall formula (1).
Vp rms = 1T∫
Where.
T --- vibration cycle.
b) may be obtained for each harmonic vibration velocity amplitude vp times the center frequency of the spectral measurement record ^ 1, 2 ,, vp vp ^ ^ like, vp rms vibration intensity should
According to equation (2).
Vp rms = 12
(Vp vp ^ 22 ^ 21 + ^ 2 + vp like Sang) (2)
3.2
Describe the state of a gasoline engine vibration integrated parameters, with "Vp s" indicates, as a vibration rating foundation.
