| 摘 要： | 当齿轮产生裂纹时,其啮合刚度变化引起的振动响应特征是实现裂纹故障诊断的重要依据.建立含有齿根裂纹故障的齿轮传动系统的8自由度动力学模型,利用龙格库塔法求解;在对求得的故障响应取多种特征值,通过对比比较选出具有冷变性的特征值.测试不同裂纹情况下不同转速的振动的故障响应,试验结果与数值分析结果相符,为齿轮传动裂纹故障诊断提供了理论基础.

| Abstract: | When gear crack is put forward,its mesh stiffness change caused by vibration response characteristics is the important basis to realize the crack fault.8 degrees of freedom dynamic model of gear transmission system with root crack fault was built using runge kutta method.A variety of characteristic values were obtained from the fault response. Select the characteristic value of cold denaturation by comparing different values.Test fault response of vibration in different rotating speed during different cases. The results of test are consistent with the results of numerical analysis, which provides a theoretical basis for the gear crack fault diagnosis. |
