Non-Linear Bolted Joint Analysis on Air Cleaner Bracket
Project Scope
- Assess structural integrity of the air cleaner bracket via bolted joint analysis
- Meet fatigue factor > 2 for high-cycle g-loads and safety factor > 1 for low-cycle g-loads
Business Challenges
- Failures reported at engine mounting locations
- Convergence issues during nonlinear simulation
- Accurate CG and mass tuning for the air cleaner assembly
ARi’s Solutions
- Resolved convergence by mesh refinement and remapping at mounts
- Delivered stress/displacement plots and detailed fatigue and slippage analysis
- Identified critical stress zones under LCF loading conditions
ARi’s Value Proposition
- Design Enhanced for Strength: Increased bolt surface area improved fatigue and safety factors
- Achieved FOS > 1: Bracket met target under LCF with reduced weight
- Validated Real-World Performance: Simulation reflected field failure points, guiding corrective action
- Extensive Expertise Applied: Over 10,000+ hours of bolted joint analysis ensured a robust solution
