Development skills in passive vehicle safety
Developments in passive safety mean designing vehicles with a maximal reduction of accident consequences for passengers, involved parties and other road users.
A high degree of passive safety is achieved through maximum absorption of energy in the chassis, coordinated restraint systems and appropriate design in the interior of the vehicle.
In this way, passive safety is an overall function of a vehicle, which is to be achieved through optimal cooperation between all the components involved.

Functional development
This comprises the optimal adjustment of all components involved and the adaptation of the entire performance to achieve complete product properties. We support you in turning global product targets, such as, for example, a specific consumer protection agency on a specific market, into necessary constituent targets (passive safety).
When it comes to functional development in simulations and tests, we concentrate on the following:
- Total system simulations (all load conditions of passive safety)
- Crash analysis
- Battery casing
- Interior (cockpit, seats, door trim)
- Restraint systems
- Connection technology
Overview: Functional levels of passive safety in the development process
We support you with crash simulations of your vehicles - from the first idea to series production
ARRK Engineering offers support with safety design in:
- Setting product goals
- Specification differentiation
- Interpreting and optimizing target fulfillment
- Technical detail optimization
- Testing carriages and whole systems
- Validation and approval

Tests
With our experience in testing, we create a perfect symbiosis of numeric prognoses, trials on real prototypes and feedback of results into numeric models for the purposes of creating the greatest possible increase in maturity.
Testing begins with the test item and continues through to the complete vehicle system - with our partner TÜV Süd Product Service GmbH, we cover the entire range of services

Methods & Tools
Form-finding methods
Which is the ideal shape for a side airbag under the given weight constraints? With our automated form-finding methods, it’s possible to determine the ideal coverage area for an airbag using an automated CAE process.
Robustness
Methods of testing robustness become relevant in relatively narrow solution spaces. If systems are already designed close to the technical limits, natural variations in starting constraints may pose the risk of systemic failure.
We establish the effects of the dummy sitting position on the robustness of the crash results.
Rough shaping methods
Rough models present a drastic reduction of a crash vehicle on its significant load path structures. With examinations of rough models, it’s possible to determine the first fundamental applied load values in crash loads.
Training concept for passive vehicle safety (CAE & testing)
We see a considerable distinction in our employees’ specialist development. We train our employees, in accordance with an established concept, in all design disciplines of passive safety, current standards and requirements, and in using crash-specific tools, such as CAE Solver.
We offer this training in German, English, Chinese and Japanese worldwide
