Suspension Tuning Optimization Assistant
Analyze suspension data to generate balanced ride and handling tuning recommendations
What You Can Do
You input suspension parameters, test telemetry, and handling feedback to receive structured tuning analysis that identifies root causes—not just symptoms. This skill synthesizes vehicle dynamics principles with real data to generate prioritized recommendations for spring rates, damping curves, anti-roll bar stiffness, and geometry adjustments that balance competing objectives like comfort and cornering composure.
Features
Transform accelerometer traces, load cell readings, and onboard telemetry into actionable insights about ride harshness, body control, and handling limits
Trace complaints (stiff front end, unpredictable body roll) to specific suspension components and parameters rather than guessing
Quantify how changes to spring rates, damping, and roll stiffness distribution affect comfort vs. sportiness simultaneously
Rank recommendations by impact and feasibility, showing which adjustments deliver the largest gain-to-effort ratio
Evaluate how camber, caster, roll center height, and compliance changes influence NVH and handling balance
Merge telemetry patterns with driver feedback to validate which data points matter most
Create phased tuning plans for iterative prototype builds or production optimization cycles
Prepare suspension compromise analysis for design reviews and stakeholder sign-off
Example Output
Example 1: Ride Comfort Issue
Input: Prototype shows excessive harshness over 15–25 Hz bumps; accelerometer peaks at 0.8 g. Current: 28 kN/m springs, 3200 N·s/m damping.
Output:
- Root cause: Underdamped natural frequency (3.2 Hz); road inputs at 20 Hz hitting secondary resonance
- Recommendation: Reduce damping to 2800 N·s/m (lowers secondary peak by 0.2 g) OR increase spring stiffness to 30 kN/m (shifts resonance above road input band)
- Trade-off: Softer damping improves comfort but increases roll in corners by 0.3°; stiffer springs preserve handling but adds 0.1 g longitudinal harshness on braking
- Next step: Test Variant B (springs + damping blend) before committing to geometry change
Example 2: Handling Unbalance
Input: Vehicle understeers at 1.0 g lateral, but roll angle (5°) feels excessive for grip level; telemetry shows rear load transfer 8% lower than front.
Output:
- Root cause: Rear anti-roll bar too soft (18 kN/m) relative to front (22 kN/m); roll stiffness ratio 1.22:1 creates neutral-to-understeer bias
- Recommendation: Increase rear ARB to 21 kN/m (improves load transfer distribution, targets 1.05:1 ratio) and soften rear bump stop (compliance adds 1° roll but recovers 0.15 g lateral feel)
- Trade-off: Stiffer rear ARB reduces understeer but may increase rear NVH on rippled surfaces
- Validation: Predict 4.2° roll at 1.0 g (vs. current 5.0°); corner speed gain ~2 km/h before driver limits
