摘要
涡旋式压缩机在微小化领域发展前景广阔,降低涡旋盘的尺寸是微小型涡旋压缩机的重要优化目标,选择结构紧凑的涡旋型线十分重要。采用变基圆渐开线代替传统定基圆渐开线,可减小涡旋盘的盘径与齿高,从而实现涡旋盘径向与轴向尺寸的缩小。为研究2个方向上尺寸的缩小对涡旋盘力学性能的影响,使用ANSYS软件分别对定基圆渐开线涡旋盘与减小盘径、减小齿高的变基圆渐开线涡旋盘进行流-热-固多场耦合分析,以应力与变形量大小作为衡量力学性能的指标,对三者进行对比。研究结果表明,通过使用变基圆渐开线来减小齿高可明显提升涡旋盘的力学性能;使用变基圆渐开线来减小盘径可更加满足轻量化与小型化的需求,但力学性能则会有所下降。
Scroll compressors have broad prospects for development in the field of miniaturization,reducing the size of scroll plate is an important optimization goal of miniature scroll compressor,and selecting a scroll profile with a compact structure is crucial.Using a variable base circle radius involute,instead of the traditional fixed base circle radius involute,can reduce the diameter and tooth height of the scroll plate,resulting in a reduction in the radial and axial dimensions of the scroll plate.In order to study the influence of the size reduction in two directions on the mechanical properties of the scroll plate,fluid-heat-solid multi-field coupling analysis on fixed base circle radius involute scroll plate and variable base circle radius involute scroll plates with reduced diameter and tooth height was performed using ANSYS software.The mechanical properties of three scroll plate were compared using stress and deformation as indicators.The research results indicate that reducing the tooth height by using variable base circle radius involutes can significantly improve the mechanical performance of the scroll plate.Using variable base circle radius involute to reduce the diameter can better meet the needs of lightweight and miniaturization,but the mechanical performance will decrease.
