Analysis and Experimental Study of the Piston Compressor Vibration
To verify the overall operation reliability of the new designed piston compressor,finite element modal simulation and vibration response test were carried out on the compressor.First,a three-dimensional model of piston compressor was established,and then optimized.After the boundary conditions were set,a finite element modal simulation was conducted on the compressor,and the theoretical results of vibration response frequency on the compressor under this boundary condition were obtained.Afterwards,the compressor was tested for the vibration response at the critical speed,the real-time working modes of the first six steps of the compressor were obtained.The comparison between the finite element modal analysis and the empirical results demonstrats that there are some errors between them,but the results are consistent,and the destructive resonance would not occur in the new designed compressor.
