中文摘要:
      为了研究可倾瓦径向滑动轴承的油膜动特性,提出一种可倾瓦径向滑动轴承油膜动力特性(油膜刚度系数和阻尼系数)的实验测试方法。利用振动理论建立系统动力学模型,根据实验测得的绝对位移和相对位移信号计算出油膜的动特性系数。实验结果表明,该方法能够排除噪声信号的干扰,具有较高的测试精度,而且简化了计算过程。
英文摘要:
      To study the dynamic characteristics of the oil film in the tilting pad journal bearings, an experimental method was presented to test the dynamic properties(including the oil film stiffness and damping coefficients) of the oil film in the tilting pad journal bearings. The dynamic model of the system was established using the vibration theory, and the oil film dynamic coefficients were calculated based on the absolute and relative displacement data acquired from the experiments. The experimental results show that this method can remove the noisy signals and improve the accuracy of testing, and can also simplify the calculating process.
