Suspension Dynamics Analysis Assistant
Analyze suspension kinematics and dynamics to optimize handling and ride comfort
What You Can Do
You can extract and validate suspension geometry parameters from vehicle designs, map compliance characteristics across load ranges, predict handling responses to suspension changes, and identify root causes of ride, handling, or durability issues. Claude helps you interpret multi-dimensional test data, analyze force paths under specific drive conditions, and generate actionable design recommendations backed by engineering principles.
Features
Extract camber, caster, toe, roll center, and instant center parameters to understand suspension behavior across travel range
Characterize bushing rates, mounting point deflection, and load-deflection curves to predict NVH and handling sensitivity
Model understeer/oversteer bias, roll stiffness distribution, and transient response to suspension geometry or stiffness changes
Predict component stresses and force flows under cornering, braking, acceleration, and bump inputs
Analyze slalom, lane change, skidpad, and compliance test results to validate suspension performance against targets
Evaluate MacPherson, double-wishbone, multi-link, and independent suspension designs for specific vehicle segments
Diagnose unexpected handling behavior, NVH issues, or durability concerns by tracing symptoms to suspension parameters
Prepare technical reports and cross-functional summaries of suspension changes and performance impacts
Example Output
Example 1: Camber Loss Analysis Input: Front camber angle vs. suspension travel data and handling feedback from test driver. Output: Quantified camber loss rate (°/mm), impact on lateral load transfer (0.3° loss = 2% roll stiffness reduction), and recommendation to adjust upper control arm geometry by 15 mm to reduce compliance sensitivity.
Example 2: Understeer Diagnosis Input: Skidpad test results showing 1.2g lateral acceleration at understeer threshold with stock suspension. Output: Root cause identified as insufficient front roll stiffness (front:rear ratio 1.1:1 vs. target 1.3:1). Recommendation: increase front spring rate 8% or reduce rear bar stiffness 6% to achieve balanced handling.
Example 3: Compliance Mapping Report Input: Bushing test data showing nonlinear load-deflection curves across temperature and load conditions. Output: Compliance matrix showing lateral stiffness (450 N/mm at 25°C, 380 N/mm at 60°C), longitudinal stiffness (620 N/mm), and mounting point deflection under 1g cornering load (±2.1 mm). Identifies resonance risk at 8.3 Hz if damping insufficient.
