Abstract

The invention discloses a gear classification method based on sound analysis, and belongs to the technical field of gear analysis and evaluation. The method comprises the following steps of S1, collecting vibration signals and rotating speed signals in the gear rotating process; S2, performing equal-angle resampling on the vibration signal and the rotating speed signal of the gear to generate a synchronous sampling signal of the vibration signal; S3, performing order analysis on the resampling data to obtain order analysis data; S4, constructing a gear grading model for the order analysis databy adopting an algorithm based on a support vector machine so as to realize grading of gears. According to the invention, the grades of the gears can be quickly distinguished.

Description

technical field [0001] The invention relates to the field of gear detection and evaluation, in particular to a gear classification method based on sound analysis. Background technique [0002] In modern gear processing, gear noise control has become an important quality control link. The strength of gear noise can reflect the load-carrying capacity, safety factor and working life of gears. The quality of gears directly affects the quality of mechanical equipment. [0003] In today's industrial applications, there are many methods for gear noise detection and analysis. The order analysis can analyze the sound signal related to the speed well by sampling the signal at equal angles, but there is a lack of a fast gear noise detection method. The method by which the grades are distinguished. The support vector machine (SVM) algorithm is a learning technique based on small samples, and this technique has the advantages of high classification accuracy, simple structure and strong ...
