A Structural and Dynamics Study for Ensuring Equipment Reliability in the High-Precision Mixing Process of Secondary Batteries

Key Points

• The aim is to verify the structural stability and operational reliability of a large blender mixer used in secondary battery manufacturing.
• Conducted finite element analysis (FEA) on the support structure changes of the external drive (motor and gearbox) to assess internal rotor behavior.
• Performed static structural analysis under gravitational and motor torque loads to calculate deflections and check for interference with the casing.
• Executed harmonic response analysis to evaluate dynamic displacement characteristics at operational speeds of 5 RPM and maximum speed of 15.8 RPM.
• Maximum displacement at operational conditions was within the design clearance limits.
• Evidence of potential resonance issues at the maximum speed of 15.8 RPM was confirmed.
