| 摘 要： | 根据Jeffcott转子的碰摩原理,在线性碰摩微分方程的基础上,基于Hertz弹性接触理论描述非线性碰摩力,建立了非线性碰摩模型,对线性模型和Hertz模型进行了比较.鉴于汽轮机碰摩位置的碰摩半径、材料都不相同,利用Hertz模型研究的不同刚度下的碰摩动力响应对判断碰摩位置有指导意义.

| Abstract: | Based on Hertz contact theory,a Jeffcott non-linear rub-impact rotor model was established by improving the linear equation and studied the difference of dynamic response between linear and non-linear model.The responses of different stiffness were presented in the paper,as the rub-impact positions have different radius and material,the conclusion has guiding significance on rub-impact position diagnosis. |
