Application of Dimensionless Parameters Based on Genetic Programming to Fault Diagnosis of Planetary Gearboxes
摘要
Abstract
Due to the difficulty of obtaining the fault characteristics of the planetary gearbox through the traditional signal processing methods and the failure of the dimension parameters in the case of variable working condition, a method based on dimensionless parameters is proposed for the fault diagnosis of planetary gearboxes. First of all, seven dimensionless parameters in different failure modes are calculated, and the genetic programming is used to construct a new hybrid diagnostic parameter. Then, the hybrid diagnostic parameter is used to distinguish the different failure modes under the condition of variable load and variable speed. Experimental results show that, this method can identify the fault state of the planetary gearboxes under different working conditions. The validity of this method is verified.关键词
