Abstract

The invention aims to provide a gear vibration noise test method. The method is used for correcting a simulation calculation model by testing vibration, noise and transmission errors of a test gear box, and obtaining a relatively accurate calculation model by calibrating and correcting the model. Through simulation analysis and testing of the test gear box, research on influence of factors such as gear basic parameters and gear precision on vibration noise can be carried out. A test bench is used for carrying out a transmission error test, a gear box vibration test, a gear box air noise test, a gear box sound source identification test and the like, and test results are compared with a calculation model for correction, so that the calculation model can have certain accuracy, and the test method has certain universality.

Description

technical field [0001] The invention relates to a vibration and noise test method, in particular to a gear vibration and noise test method. Background technique [0002] Gear transmission is an important form of 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 use requirements, the transmission power of gears is gradually increasing, and the operating speed is gradually increasing, and the requirements for vibration and noise of gears are also getting higher and higher. Gear vibration and noise are important indicators for evaluating gear transmission performance. Research on gear vibration and noise can provide technical support for the design and manufacture of high-performance gears. In view of the high-speed and heavy-load operating environment of ship gears, the existing gear transmission test benches are mainly open test benches. The test c...
