摘要: 以拖拉机涡旋压缩装置为研究对象,利用MatLab建立了一种涡旋压缩装置的复杂组合式涡旋线数学模型,该涡旋线由基圆渐开线、高次曲线及圆弧组成。进一步借助CFD对涡旋压缩装置的内部流场进行数值模拟,得出该组合式涡旋曲线压缩腔的内部流场分布及内部流场与涡旋线曲率的关系,为进一步研究组合式涡旋线压缩装置的设计方法提供理论支持。Abstract: This paper takes the tractor scroll compression device as the research object, and establishes a complex combined mathematical model of scroll compression device by using MATLAB. The scroll line consists of basic circle involute, high order curve and arc. Furthermore, the internal flow field of the scroll compression device is simulated by CFD, and the distribution of the internal flow field and the relationship between the internal flow field and the curvature of the scroll line are obtained. To provide theoretical support for further research on the design method of combined scroll line compression device.
