| 摘 要： | 基于热应力场耦合建立了汽车涡旋压缩机涡旋盘有限元模型,涡旋齿载荷边界条件设置为流场离散,在气体压力载荷单独作用、温度场载荷单独作用以及两者耦合作用这三种情况下,对涡旋盘进行受力分析和变形分析, 讨论不同主轴转角的涡旋齿的刚度和强度,最后得到涡旋齿的变形规律和应力分布。分析结果表明:当涡旋盘压缩腔运动到排气孔位置时,涡旋盘处于变形与应力最大的状态,热变形是影响涡旋盘整体变形的主要因素。

| Abstract: | The finite element model of scroll compressor based on the thermal stress coupled field is established. The flow field is discretized as the load boundary condition of wraps. The stress distribution and deformation of wraps under the action of gas pressure, thermal loading and their interactions are analyzed, and the strength and stiffness of wraps in five different shaft rotation angles are discussed. The stress distribution and deformation discipline of wraps are obtained respectively. The results indicate that the stress and deformation are the largest when compression chamber is moving near the vent position, and thermal deformation is the main factor of affecting the overall deformation of scroll. |
