在行星齿轮箱中，存在多个振动源，振动信号的传递路径由于载体的旋转而发生变化。对某行星齿轮箱的振动信号进行建模，研究其在健康状态和齿裂状态下的振动特性。建立了振动源信号的动态仿真模型。提出了一种改进的汉明函数来表示传输路径的影响。通过综合考虑多个振动源的影响和传动路径的影响，得到了行星齿轮箱的合成振动信号。通过对产生的振动信号的分析，揭示了行星齿轮箱的一些振动特性，并对太阳齿轮齿裂纹的故障症状进行了识别和定位。最后，对该方法进行了实验验证。(C) 2014 Elsevier Ltd.版权所有。
In a planetary gearbox, there are multiple vibration sources, and the transmission path of vibration signals changes due to the rotation of the carrier. This study aims to model the vibration signals of a planetary gearbox and investigate the vibration properties in the healthy condition and in the cracked tooth condition. A dynamic model is developed to simulate the vibration source signals. A modified Hamming function is proposed to represent the effect of the transmission path. By incorporating the effect of multiple vibration sources and the effect of transmission path, resultant vibration signals of a planetary gearbox are obtained. Through analyzing the resultant vibration signals, some vibration properties of a planetary gearbox are revealed and the fault symptoms of sun gear tooth crack are identified and located. Finally, the proposed approach is experimentally verified. (C) 2014 Elsevier Ltd. All rights reserved.
