• Testing & Validation
• Homologation & Certification
• CAE Characterization on of crash materials in own material laboratory

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.

This way, passive safety is an overall function of a vehicle, which is to be achieved through optimal cooperation between all the components involved.

ARRK strengths

• Functional development
• Functional levels in the development process
• Methods & tools
• Training concept

Functional development

This comprises the optimal adjustment of all components involved and the adaptation of the entire performance to achieve complete product properties. ARRK supports customers 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, ARRK concentrates 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

ARRK supports customers with crash simulations of 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
• Methods & Tools
• Form-finding methods

Which is the ideal shape for a side airbag under the given weight constraints? With their automated form-finding methods, at ARRK 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.

ARRK can also 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)

ARRK sees a considerable distinction in their employees’ specialist development. They train their 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.

This training is offered in German, English, Chinese and Japanese worldwide
