Verification test method of gearbox noise prediction model

Abstract

The invention relates to a verification test method of a gearbox noise prediction model and relates to the technical field of test methods, The verification test method includes a gearbox finite element model matching test S1, a gear transmission error test S2, a gearbox foot vibration and radiation noise test S3, a gearbox radiation noise source test S4, model matching S5, determination of gear meshing excitation S6, determination of foot vibration and radiation noise S7, identification of sound source and sound field distribution S8, calculation of the level analysis software platform S9, debugging, calibration and gearbox air noise pre-estimation S10. The verification test method of the gearbox noise prediction model measures the gearbox gear meshing excitation, the gearbox foot vibration, the sound radiation measurement, sound source recognition and the sound field, compares the test data with a calculation platform model. A verified calculation platform can be used to estimate the gearbox air noise.

Description

[0001] Technical field: [0002] The invention relates to the technical field of test methods, in particular to a verification test method for a gearbox noise prediction model. [0003] Background technique: [0004] The gearbox is an important power device for power transmission, and plays an important role in the fields of automobiles, ships, aerospace and aviation. With the development of science and technology and the improvement of people's needs, the transmission power of the gearbox is gradually increasing, and the operating speed is gradually increasing, and the requirements for the vibration and noise of the gearbox are also getting higher and higher. The gearbox air noise prediction technology originated in Germany. After years of development, a relatively complete theory has been formed. However, at present, there are still many problems in the noise prediction method, which needs further modification and verification. Therefore, it is necessary to develop a gear bo...
