Dynamic- Modal Analysis on Genset Package
Project Scope
- Identify natural frequencies and mode shapes of the genset package
- Improve critical modes – specifically vertical bending and twisting frequencies
Business Challenges
- Accurately tune mass and center of gravity for assemblies and overall package
- Maintain low node count to reduce simulation time
ARi’s Solutions
- Conducted modal analysis to extract natural frequencies and mode shapes
- Developed Campbell diagram to pinpoint resonance risks
- Performed design iterations to meet frequency targets
ARi’s Value Proposition
- Improved Structural Dynamics: Bending mode frequency increased from 24.2 Hz to 32.5 Hz, twisting mode from 49.2 Hz to 58.4 Hz
- Optimized Design Through Iteration: Multiple refinements ensured reliable and efficient performance
- Faster Simulation Cycles: Controlled model size helped reduce solving time
- Reduced Vibration Risk: Final design avoided resonance, improving equipment longevity
