Dynamic Frequency Response Analysis
Project Scope
- Evaluate the structural integrity of the tractor’s flywheel housing under dynamic excitation
- Ensure fatigue factor exceeds 2 as per acceptance criteria
Business Challenges
- Correlated FEA results with actual field failures
- Optimize weight while maintaining structural stiffness and safety
- Accurately simulate dynamic conditions using KINCOUP elements for rotating parts
ARi’s Solutions
- Identified natural frequencies and corresponding mode shapes
- Developed Campbell diagram to locate potential resonance points
- Highlighted stress concentration areas through dynamic analysis
ARi’s Value Proposition
- Targeted Design Enhancements: Suggested fillet radius modification at high-stress zones, improving durability
- Failure Correlation Achieved: Analysis matched field observations, validating simulation accuracy
- Weight Optimization: Supported lighter design without compromising safety
- Improved Fatigue Life: Design modifications helped exceed the required fatigue factor of 2
