| 摘 要： | 根据运动过程中的润滑状态,摩擦力一般产生于两个方面,一是黏性流体的剪应力,二是摩擦界面相互接触峰元的剪切作用.针对这两方面因素,基于对涡旋盘在运动过程中处于混合润滑状态的分析,考虑到动涡盘受倾覆力矩的作用,在运转过程中瞬间发生弹性变形,接触面上产生楔形角,建立了动静涡旋盘摩擦模型;运用平均雷诺方程和固体接触理论,推导了摩擦力和摩擦功耗的计算公式,并且应用有限差分法和数值积分法对实际的涡旋盘的摩擦力、摩擦功耗作了计算.

| Abstract: | Accroding to the state of lubrication,friction force brings two sides,one is viscosity fluid shearing strength,the other is contact peak shearing strength.Due to the two factors,based on the blend state of lubrication of scroll plate,considering the capsizal moment effected on the orbiting scroll,the wedge angle is caused by the elastic deformation,the friction model is established.Applied the average Reynods equation and solid contact theory,the friction force and friction work are deduced,besides calculat... |
