For the dry conformal friction pairs, the contact damping effect between rough surfaces should be considered. In this study, a new rough surface damping contact (RSDC) model is firstly proposed and then applied to the spatial tribo-dynamics analysis of the variable stator vane (VSV) mechanism, which consists of dry conformal friction joints. The results show that the contact damping is very significant and cannot be ignored, otherwise the calculation process will not converge, which is quite different from the case when lubricants exist. In the tribo-dynamics simulation of the VSV, the damping effect play a role in ensuring stability, and the clearance size affects the distribution of damping forces and rigid forces.

对于干共形摩擦副，应考虑粗糙表面之间的接触阻尼效应。在这项研究中，首先提出了一种新的粗糙表面阻尼接触 (RSDC) 模型，然后将其应用于由干保形摩擦接头组成的可变定子叶片 (VSV) 机构的空间摩擦动力学分析。结果表明，接触阻尼非常显着，不能忽略，否则计算过程不会收敛，这与存在润滑剂的情况有很大不同。在VSV的摩擦动力学仿真中，阻尼效应起到保证稳定性的作用，间隙大小影响阻尼力和刚性力的分布。
