摘要：

In order to accurately calculate the stress and deformation of wraps in scroll compressor, the calculation method of stress and deformation based on flow field simulation was proposed. The pressure field and temperature field were obtained through numerical simulation of the working process in scroll compressor. The pressure field and temperature field were loaded as boundary condition to calculate the stress and deformation of wraps, and the stress distribution and deformation discipline of wraps under gas pressure, thermal loading and their interactions were obtained respectively. The axial deformation and radial deformation of wraps were analyzed. The differences of deformation between the orbiting scroll and the fixed scroll were compared, and the stress distribution and deformation of wraps in different shaft rotation angles were discussed. The results show that the stress and deformation of the orbiting scroll reach the maximum value at the end of the compression process, and the maximum stress value and the deformation value locate at the root and the top of wraps in the centre respectively.
