The aim and outcome of a crash analysis

The aim of a crash analysis is to evaluate the structural response of a vehicle, aircraft, or component during an impact event and to assess occupant safety, structural integrity, and energy absorption capability. It helps engineers optimize designs to minimize injury risk and comply with safety regulations.

The outcome of a crash analysis is a detailed assessment of deformation patterns, stress and strain levels, energy absorption, intrusion into occupant spaces, acceleration loads, and potential failure modes. These results are used to improve crashworthiness, enhance safety performance, and validate compliance with applicable standards.

Analysis types we run

Frontal impact analysis

vehicle or structure behavior during head-on collisions

Side impact analysis

structural integrity and occupant protection during lateral impacts

Rear impact analysis

deformation and occupant loads resulting from rear-end collisions

Rollover analysis

structural performance and occupant protection during rollover events

Occupant safety analysis

dummy models and restraint systems to evaluate injury criteria and passenger protection
Human-Body Models (HBM) to evaluate real human body behaviour

Pedestrian safety analysis

risk of head injuries when a pedestrian's head strikes the hood, windshield or A-pillars
injuries to the lower leg, knee and femur caused by vehicle front-end impact

Bird strike & foreign object impact analysis

effect of impacts from birds, debris or other objects on aircraft and critical structures

Drop test analysis

impact resulting from a fall or hard landing
common in packaging, equipment and hand-tool design

EN 15227 crash scenarios for a new wagon design

A new wagon design had to be analysed based on the crash scenarios of EN 15227. We modeled all the crash scenarios of the standard and evaluated the deformations, strains and absorbed energy of the structure, and made design suggestions to improve crashworthiness. The result was a prototype design optimized for crash safety.

What are the steps in a typical project?

Schedule a discovery call and together we decide what is needed to achieve your design objectives.

Receive a proposal within 3 days. Project length scales with scope — engagements typically run from several months to even longer.

When all input data specified in the proposal is given, a kick-off call gets the project started.

We issue a project status report document outlining background, modeling details, boundary conditions to ensure common understanding of the details.

We work collaboratively and quickly to meet objectives, maintaining focus on how design variants will be impacted based on simulation results.

The project report is updated with simulation results and design suggestions, and meetings are used to discuss conclusions and define next steps.

Achieve greatness.
