CRASH AND IMPACT

Experts in Crash for Automotive and Aerospace

Services // Analysis // Crash & Impact

Crash and Impact are events with short time duration that require the use of explicit analysis to capture the effects of momentum. At Calcate, our engineers have decades of experience in performing crash and impact analysis in products that range from a vehicle hitting a barrier, a bird hitting an aircraft to a consumer product dropping from a table.

The analysis of crash and impact presents many unique challenges, including highly non-linear materials, short durations, complex boundaries, special materials (birds, water, composites), and multi-stage loading. Our engineers have the knowledge and experience to gather the required data, set up complex models, and load cases using leading-edge commercial software. We then post-process the results to obtain the critical information needed to meet the desired performance and regulatory standards.

Common Crash & Impact Assessments

  • Product drop testing
  • Vehicle crash analysis:
      • Vehicle level: Front, side, rear, roll-over
      • Head impact – Interiors: dashboard, pillars, headliner
  • Aircraft crash analysis:
    Drop testing, Battery Protection (EVTOL)
  • Accident/failure analysis
  • Impact protection

Aerospace & Automotive Seating

At Calcate, our engineers have a wealth of experience in the analysis and testing of aerospace and automotive seating. We have created detailed and correlated dynamic models either from scratch or using legacy models to perform the following:

  • Vehicle Seating:
      • Seatbelt anchorage, knee intrusion, child seat retention
  • Aircraft Seating:
      • 16G, 14G, HIC & occupants safety
      • Economy, business and luxury seating

Aside from crash and impact, our engineers have worked on the seating products from inception to certification, performing sizing, static, abuse, and fatigue analysis. We have also worked on the development tests, FEA – Test correlation, and certification testing at 3rd party test facilities.

Bird Strike Analysis

At Calcate we have expertise in bird strike analysis for the aerospace industry, on structures including fuselage, wings, radome, windows, and engines using commercial software. Our bird strike analysis capabilities include :

  • Creating an FEA model of bird and target structures.
  • Selecting impact locations for FEA & physical testing
  • Working with test facilities to test with gelatine and real birds
  • Assessing structures post bird strike in FEA and physical testing
  • Correlating FEA and physical testing results (gelatine & real-bird)
