摘要(Abstract):

采用Solidworks建立了无油涡旋压缩机动、静涡旋盘的三维模型,运用ANSYS分析软件对涡旋压缩机动涡盘分别在气体力、温度、惯性约束条件下以及在多场耦合载荷下涡旋齿的变形和应力分布规律进行了分析,并研究了不同齿厚和齿高的动涡盘涡旋齿在多场耦合载荷作用下的变形情况,得到涡旋盘的应力分布和涡旋齿变形情况。分析结果表明,对涡旋齿的变形影响最大的载荷是温度载荷场;在腔内气体被压缩时,涡旋齿始端部位温度最高,所受气体力也最大;耦合场下涡旋齿始端顶部变形最大,最大应力出现在齿根部位,且耦合场的最大应力不是各载荷应力的叠加;涡旋齿越高变形越大,涡旋齿越厚变形越小,分析研究结果为定量化确定无油涡旋压缩机的轴向间隙和径向间隙提供了理论依据。
The 3D models of orbiting and stationary scroll members of oil-free scroll compressor were built using the Solidworks. The deformation and stress distribution laws of the orbiting scroll member under the constraint conditions of gas force,temperature and inertia and under the coupled load of multiple fields were analyzed using the ANSYS software,respectively. The scroll wrap deformation of orbiting scroll member of different thickness and scroll wrap height was investigated under the action of coupled load of multiple fields,and the stress distribution law of the scroll member and deformation law of scroll wrap were obtained. The research results show that the maximum load that affects the deformation of the scroll wrap is the temperature field. When the gas in the chamber is compressed,the temperature at the beginning end of the scroll wrap is highest,and the gas force is maximum;the maximum deformation occurs at the top of beginning end of the scroll wrap under coupled field,and the maximum stress appears at the root of the scroll wrap,and the maximum stress of the coupled field is not the superposition of load stresses.The higher the scroll wrap,the bigger the deformation. The research results provide a theoretical basis for quantitative determination of axial and radial gap of the oil-free scroll compressor.
