Chassis Development

The chassis: requirements are still increasing.

Driving dynamics, vehicle comfort and driving behavior define the character of an automobile. The challenges in vehicle development are increasingly changing. The increasing use of electronic driving control and assistance systems demands intense integration of electronics development in the development process. Energy efficiency and the minimization of power loss in the chassis also have a prominent influence on CO2 reduction-potential in the vehicle. Chassis development today must achieve more and satisfy more complex requirements than ever before.


With us, efficiency is a key element of development.

At Bertrandt you will find all the important expertise to implement your specifications and framework requirements.
We will accompany you every step of the way – from the development of mechanical and mechatronic components, right to concepts and trials for chassis properties.

  • Axle / wheel mounting
  • Spring / shock systems
  • Roll stabilization
  • Brakes
  • Laying of supply lines
  • Steering
  • Pedal systems
  • Wheel / tire / bearings

In concept development the technical framework conditions for chassis systems, modules or components that are to be developed are examined. Our employees produce variant comparisons, benchmarks and concept constructions for individual parts or as package. This is how the ideas of our customers are turned into solid concepts.

  • Package development / DMU
  • Benchmarks
  • Feasibility studies
  • Variant development
  • Assembly simulations
  • Envelopes (static / dynamic)

For the overall functionality of chassis systems each individual component is of importance – from wheel carrier to brake line. Our development engineers have already gained experience from numerous projects, so they are known for their extensive specialized knowledge of components of all chassis systems. They have a keen knowledge of the environment of these components in the vehicle, which allows them to develop the right solutions.

  • Axle components and assemblies
  • Brake components
  • Steering components
  • Powertrain elements mounting
  • Wheels / tires
  • Springs / shocks

In module development the overall functionality of a unit comprising multiple components is presented. Finding solutions for the requirements in your technical specifications is naturally at the forefront. In the process it is necessary to keep an eye on the big picture. Here, in interactions with clients, suppliers and development departments, Bertrandt is a dependable partner. This pertains to front and rear axle, wheel brake, brake actuation, steering or steering column, and exhaust and fuel systems.

  • Front and rear axle
  • Wheel brake
  • Brake actuation
  • Steering / steering column
  • Exhaust systems
  • Fuel systems

In order to be able to optimally integrate the chassis system into a new vehicle it is necessary to precisely understand all chassis functions and the interfaces to the vehicle. Digital mock-up (DMU), physical mock-up (PMU) and prototyping are becoming increasingly important here. Bertrandt has the necessary experience and the proper technical equipment to provide you with optimum support to deal with these challenges.

  • Package / concept
  • Assembly analysis
  • DMU
  • Development of media-carrying systems
  • Consideration of moving parts
  • Consideration of module requirements
  • Support for vehicle construction based on different chassis variants

For each development, technical calculations are important so that concept and project decisions can be made early on. Prompt and reliable conclusions on service life and vehicle behavior allow the shortening of development times and the reduction of costs.

  • Stiffness / strength
  • Multibody simulation
  • Topology optimization
  • Vibration (acoustics / NVH)
  • Flow simulation
  • Calculation models
  • Simulation of driving dynamics
  • Control system simulation

Mobility is rapidly changing. Requirements on chassis functionality, comfort, and energy efficiency are increasing. As a result, complex testing scenarios are becoming necessary. Bertrandt supports its customers in everything from the testing of functionality and testing facility analysis to coordination and testing of the entire vehicle. This is done using a variety of state-of-the-art testing and analysis methods.

  • Data acquisition and evaluation
  • Component testing / testing facilities
  • Vehicle testing
  • Endurance testing
  • Vehicle structure
  • Evaluation of vehicle dynamics
  • Subjective vehicle evaluation
  • Objective vehicle evaluation
  • Virtual vehicle testing
  • HiL testing
  • Operator models

In modern motor vehicles, mechatronic chassis systems are increasingly gaining the upper hand. They make a contribution in the implementation of integrated comfort, safety and assistance systems. To implement customer requirements, Bertrandt can contribute extensive knowledge and a great deal of experience related to complex mechanical, electronic and hydraulic subsystems. We are also very familiar with the dynamics of the overall vehicle. We use state-of-the-art development tools to design innovative systems with reliable functionality.

  • System concepts
  • System integration
  • Validation of properties
  • Development of mechanical and hydraulic components
  • Development and application of the software for driving dynamics functions
  • System networking
