Crashworthiness CAE Skill

Purpose

Enable crash simulation setup and analysis for occupant protection optimization and regulatory compliance testing across frontal, side, rear, and pedestrian impact scenarios.

Capabilities

• LS-DYNA, Radioss, PAM-CRASH model preparation
• Crash barrier and dummy model setup
• Material card calibration (metals, plastics, foams)
• Energy absorption optimization
• Intrusion measurement and tracking
• Occupant injury criteria calculation (HIC, chest G, femur load)
• NCAP and FMVSS regulation test setup
• Pedestrian protection simulation

Usage Guidelines

• Calibrate material models against component test data
• Validate dummy models against certification tests
• Use mesh sizes appropriate for crash simulation accuracy
• Monitor energy balance and mass scaling effects
• Track intrusion at critical occupant locations
• Generate comprehensive crash reports for design reviews

Dependencies

• LS-DYNA
• Radioss
• PAM-CRASH
• ANSA/META pre/post

Process Integration

• SAF-003: Crashworthiness Development
