Article Synopsis
- A simplified concentrated mass model and an ANSYS simulation model are developed to enhance the accuracy of modal analysis for a four-stage centrifugal pump rotor system with a balancing disc.
- The study identifies significant discrepancies in mode shapes primarily due to simplifications in calculating the moment of inertia and proposes an optimized mathematical model, which shows better agreement with simulation results.
- The optimized model significantly reduces errors in natural frequency calculations, improving accuracy from percentages as high as 12.96% down to as low as 1.56%, confirming its effectiveness for centrifugal pumps with back blades.
