Test Benches for Active Driving Dynamics Systems

From the initial concept idea to the turnkey system: we develop and realize test benches that test mechanical, electromechanical and electrohydrostatic vehicle dynamics systems under realistic conditions.

We attach great importance to short set-up times and user-friendly handling. Precisely dimensioned, needs-based actuators and powerful automation ensure that your tests are efficient, versatile and reliable. Our solutions integrate seamlessly into existing processes and toolchains.

If required, we can add environmental simulations to your test bench - for even more realistic test conditions. And if you wish, we can supply you with the complete turnkey system from a single source.

Typical areas of application for mechatronic chassis dynamometers

Our portfolio includes state-of-the-art test benches for electromechanical driving dynamics systems, for example for active dampers or active roll stabilizers. We rely on innovative and flexible solutions that are precisely tailored to your requirements. We also develop customized test benches for special areas of application, such as testing under varying environmental influences for realistic, combined load scenarios.

In this way, we ensure that you can develop your chassis systems faster, optimize them in a targeted manner and reliably safeguard them. Our test benches not only provide you with precise results, but also a clear advantage in the market thanks to the highest quality, efficiency and future-proofing.

Function test benches for active dampers

Our damper function test benches make it possible to comprehensively test active damper systems under realistic conditions and defined environmental influences. This allows functions, performance and reliability to be specifically analyzed, validated and continuously improved.

  • Comprehensive function test of active damper systems
  • Precise characterization of the dynamic damping behaviour
  • Reliable validation of performance and service life
  • Realistic simulation of critical driving scenarios
  • Targeted testing under defined environmental influences

Test benches for active roll stabilizers

Our test benches for anti-roll bars are ideal for characterizing your systems during development and series production. They offer extensive possibilities for development, optimization and validation - even under defined environmental influences, so that properties can be specifically validated and improved.

  • Functional testing of roll stabilizers
  • Characterization of static and dynamic behaviour
  • Validation of operational stability
  • Simulation and validation of system behavior in failure scenarios
  • Simulation and investigation of wear mechanisms under environmental conditions

Complete system test benches

Our complete system test benches enable the simultaneous testing of several chassis systems in combination. They simulate realistic operating conditions and thus support the development, optimization and validation of system and component functions.
In addition, endurance tests and hardware-in-the-loop (HiL) tests can be integrated. Thanks to their modular design, the test benches can be flexibly adapted to new requirements at any time.

  • Development, optimization and validation of system and component functions
  • Analysis of performance parameters and control quality in the system network
  • Endurance and HiL driving tests
  • Simulation and validation of system behavior in fault scenarios

The most important modules of our test benches for chassis components

  • Drive technology

    The drive technology simulates the effective displacements. It therefore essentially determines the performance and also the possible area of application of your test stand.

    Depending on the test cases to be simulated, there are sometimes very different requirements for the actuators and their control. The selection of a suitable actuator, its dimensioning and the design of the control system are therefore model-based for the test cases to be mapped, taking into account the properties of all relevant test specimens. In addition to your specific requirements for force, speed, control accuracy, dynamics, latency and synchronization behaviour, we naturally also take the investment and operating costs into account.

    We are not bound by any operating principle. On the contrary: our aim is to offer you the best actuators for your specific requirements, both technically and economically.

  • Mechanical structure

    When conceptualizing and designing the mechanical structure of your test bench, we attach great importance to

    • high rigidity
    • a favorable inherent behavior of the structure
    • low maintenance requirements
    • large set-up areas
    • simple, fast and ergonomic set-up
    • consideration of the conditions and constraints at the intended installation site.

  • Temperature control and media application

    Naturally, we offer you suitable and fully integrated solutions for the temperature control or air conditioning of your test specimen.

    We also offer automated systems for the introduction of salt spray, dirty water, sludge and dust to identify weak points in corrosion-related long-term effects on your test specimens.

  • Remaining bus simulation

    Solutions from various manufacturers have become established for residual bus simulation and communication with the test object. We integrate your preferred hardware and software solutions into your test bench, ensuring that you can continue to use your established processes and toolchains. This allows you to utilize synergies and deploy your personnel flexibly.

  • Wiring system simulation

    The on-board power supply simulation is used for the electrical power supply of the test object. In the simplest case, this module comprises a recuperating power supply unit, monitored power contactors for the automated switching of the terminals and measurement technology for recording the currents and voltages.

    There are also various expansion options. Examples include a redundant on-board power supply simulation with two separate bidirectional power supply units, highly dynamic power supply units, an additional logic supply or the integration of SuperCaps for voltage stabilization for dynamic load cases. Other options include a connection option for external battery simulators or power supply units, measurement technology extended to include quiescent current measurement or relay isolating adapters for highly automated simulation of electrical faults.

  • Measurement technology

    Measurement technology is another key component of your test bench. Depending on your requirements and wishes, our measurement technology team will develop various implementation options and discuss the advantages and disadvantages, existing conflicts of interest and expansion options with you. Here too, we are not tied to any particular manufacturer, so we can work with you to develop and implement the solution that best suits your requirements and boundary conditions.

  • Individual automation solutions

    We offer you customized software and hardware solutions for your test bench - tailored to your individual requirements. When designing suitable system and function architectures, we naturally take into account your existing automation solutions, processes and toolchains in addition to your standards, preferred lists and equipment regulations. If necessary, we implement individual interfaces, e.g. for the integration of additional peripheral devices, communication with higher-level automation systems or for the integration of the test environment into your database systems.
