General information

Since the very beginning of motorcar manufacturing, engineers have been constantly working on the development and optimization of all chassis components in order to improve ride comfort and active safety at the same time. ika’s chassis department follows this tradition. Thereby, our engineers master all steps in vehicle development: We offer our customers a large variety of development services beginning with conception and simulation through detailed design and prototyping up to testing procedures both on our test tracks and on our modern testing facilities.

Various tools are available at ika to support conceptual and advanced design of new suspensions. Three-dimensional CAD software (such as CATIA or IDEAS) enables us not only to define kinematical relationships but also to investigate free travel on newly developed chassis systems. By this means, potential errors can be minimized in the design phase, so that the costly prototype manufacturing can be prepared most efficiently. Prototype parts are either built up at own workshops or we fall back to the support of long-standing manufacturing partners.

The simulation of vehicle dynamics is widely used by vehicle manufacturers and therefore represents another main point of chassis development at ika. At the moment, we are employing ADAMS® and SIMPACK®, two highly sophisticated software tools that have been acknowledged globaly. Not only the simulation of multi-body-systems, but also a linkage to FEA-tools is possible in order to take elastic deformations of chassis components into account or to investigate the stiffness and strength of components. In this context, we are working on the field of lightweight design of chassis systems.

Especially the development of control algorithms of electronic chassis control systems is another focal working point. The software tools MATLAB®/SIMULINK® are brought into the MBS-simulations. Other tools, e. g. the dSpace Autobox or digital control units, are also available for the application to the target platform. In cooperation with the electronics department we are capable of the whole path of active chassis systems development.

Besides simulation activities driving tests remain a major part of chassis development. We are performing driving tests to assess and validate simulation results on our own test track.
Equipped with the latest measuring devices (including autocollimators and gyroscopic platforms), we are able to carry out any kind of driving manoeuvres. The experience of our testing engineers guarantee reliable and fast measurements to solve difficult problems.

For the experimental analysis of full vehicles or chassis components, ika employ various modern testing facilities. Next to a servohydraulic test rig with more than nine cylinders we have a wheel-alignment analyzer (K&C test rig) to investigate the kinematics and elastokinematics of both complete vehicles and single axles. Here, various suspension characteristics such as roll stiffness, longitudinal and transversal elasticity, bump steer and steering compliance can be examined.

On two tire test benches we are able to measure the out of tire slipping, crashing and creeping resulting forces and analyze the static and dynamic features of the tires. Finally, we can measure the mass moment of inertia on both full vehicles and car components on different test rigs to generate reliable data for the MBS programs.
