Project Background
A domestic automaker needed comprehensive evaluation and optimization of vehicle crash performance during new model development to meet C-NCAP five-star safety standards.
Technical Solution
- Frontal Crash: 100% overlap rigid barrier and 40% offset deformable barrier
- Side Impact: Mobile deformable barrier side impact
- Pedestrian Protection: Head and leg impactor simulation
- Restraint System: Seatbelt and airbag matching optimization
Analysis Content
- Full Vehicle Crash: LS-Dyna explicit dynamics analysis
- Dummy Injury: HIC, chest compression, thigh force evaluation
- Structural Deformation: Crash process deformation patterns and energy absorption
- Optimization Design: Key component thickness and material optimization
Project Results
- Crash safety meets C-NCAP five-star requirements
- 8% weight reduction in key components
- 3-month reduction in development cycle
