Simulation and structural optimization of deformation of compressor suction valve
Based on the research on the deformation of the suction valve,a fluid structure coupling model of the suction valve was established,and the longitudinal and transverse displacement deformation generated by the suction valve in one working cycle was studied.The results show that the maximum longitudinal displacement deformation of the suction valve is 2.431 9 mm,and the maximum transverse displacement deformation is 0.066 5 mm.The strain of the suction valve is mainly concentrated at the bolt hole and the longitudinal displacement has a significant impact.According to the stress-strain distribution law of the suction valve,different sizes of ribs are added to optimize the structure of the suction valve,and the influence of rib size on the deformation of the suction valve is analyzed and compared.Optimization shows that when the rib size of the suction valve is 25 mm ×4 mm ×0.1 mm,the longitudinal displacement and strain of the suction valve can be significantly reduced.
