含裂纹故障多自由度齿轮系统的动力学分析
摘要
Abstract
This study focuses on the dynamic characteristics of the four-freedom gear system with local crack defect to explore the crack nonlinear dynamic mechanism. The dynamic model of the gear system with crack defect, time-variant mesh stiffness and nonlinear clearance are established to investigate the effect of crack defect on mesh stiffness. The dynamic characteristics with the evolvement of crack and other system parameters are studied by employing harmonic balance method, which reveals the amplitude jump, bifurcation phenomenon and internal resonance. The results obtained herein can provide a theoretical basis for the design and crack fault diagnosis of gearbox.关键词
