摘要
The fixed scroll of the scroll compressor is usually immovable, and the deformation of the scrolls may lead to the operation stuck, which may be avoided by designing the fixed scroll as floating one. However, the introduction of floating fixed scroll will inevitably cause the variation of the dynamic characteristics, so it is necessary to establish a simulation model to explore the influence of floating fixed scroll. In this study, a tribo-dynamics model considering floating fixed scroll is established, which couples the key friction pairs composed of fixed scroll, orbiting scroll and frame to reveal the influence of floating scroll on tribological and dynamics performance. The variation of the lubricant viscosity and boundary pressure as well as the deformation of components are included in the model to consider the real working conditions. The results show that compared with the fixed scheme, the floating scheme provides a compensation space for the components deformation, which is conducive to the operation stability; The floating scheme can not only ensure the sealing of the compression chamber, but also reduce the friction work by 53% compared with the fixed clearance of 4µm.
