Abstract:
In this paper the vibration of a screw pump unit was studied. Firstly the modal of this pump unit was calculated, which was possible thank to the exact finite element model. And the exactness of the result was verified by comparing with the testing one. Based on the correct simulation modal, the load is identified using the experimental results, and the accuracy of the identification is confirmed using the response error. Combined the response spectrum, the load spectrum and the modal analysis results, the causes and control methods of the screw unit's vibration are analyzed. Finally, according to the foregoing calculation results, the system is simulated and optimized. The identified load is loaded on the optimized structure. The responses calculated are compared with the original structure and the optimized results are evaluated.
