- An impeller consists of a rotating disc called the hub, to which blades are attached.
- The rotating motion of the impeller blades moves the fluid outwards.
- The impeller is always placed directly onto the shaft of the electric motor so that it spins at a very high speed, which leads to a continuous vibration.
- Here modal analysis of the impeller is done to understand the frequency change.
- The mode shapes represent the bending modes and deformations of the impeller and impeller blades.
- The following model is solved using CalculiX solver.
Natural mode shape
