| description | This article presents a new approach aiming to reducing pump vibration by modifying its baseplate structure. The finite element models of the vertical pump were established and validated by the experimental impact test. The natural frequencies of pump were mapped in both experimental and numerical methods. The weak stiffness of the baseplate was identified as the root cause for the pump vibration. A topology optimization was used for enhancing the stiffness of baseplate and controlling its weight. The new baseplate was designed according to the inputs from optimization results and manufactured by the casting method. Both the vibration tests and the numerical simulations were carried out to investigate the vibration behaviors of the optimized pump model. The differences of vibration characteristics between original and optimized pumps were evaluated using 1/3 octave-band filter technique. Results show that the vibration was suppressed, and the resonance at 31.5 Hz was eliminated using the optimized baseplate. In particular, the maximum vibration amplitude of the vertical pump was reduced from 4.05 to 1.75 mm/s at the low flow rate condition. It was experimentally confirmed that the vibration amplitude of the optimized model complies with the requirements of the International Organization for Standardization standard and ensures the pump can operate stable for a long time. |
