多载荷作用下动涡旋盘应力和变形研究

Research on Stress and Deformation of Dynamic Vortex Disk under Multi-load

利用NX建立动涡旋盘的三维实体模型,运用有限元法研究了动涡旋盘在气体载荷、温度载荷下的应力与变形;并对气体载荷以及温度载荷耦合作用下的动涡盘应力和变形进行了研究;仿真结果表明,温度载荷作用下,最大应力和变形发生在涡旋齿齿头部位;气体载荷作用下,最大变形在啮合点处,最大应力在涡旋齿中心及尾部;耦合作用下在端板与涡旋齿连接处产生最大应力,在涡旋齿中心及尾部位产生了最大变形。

The 3D models of dynamic scroll disks in NX software are set up,the stress and deformation of dynamic vortex disks under the condition of the given gas load and constraint conditions are studied by the finite element analysis method,and the stress and deformation of scroll disk under coupled action of gas load and temperature load is also studied.Simulation results showed that,under the action of temperature load,maximum stress and deformation occurred at the tooth head of the vortex teeth,that the maximum deformation occurred at meshing points and that the maximum stress occurred at the center and the tail of the scroll teeth.The maximum stress was generated at the connections between end plate and scroll teeth while the maximum deformation occurred at the center and the tail of the vortex teeth.
