The load-bearing unit

The chassis is often incorrectly thought of as a simple, solid steel frame. But this load-bearing unit has evolved significantly in the course of its development. In addition to the advent of lightweight construction with increasing requirements of rigidity, increasing numbers of system-relevant elements are also associated with the chassis: Even the batteries of e-vehicles are now fully integrated in the chassis architecture.

System optimisations in the NVH area

Our many years of experience in "measuring technology for expansion measuring strips" and our expertise in the field of acoustics/NVH provides our customers with the perfect symbiosis for services in the field of transfer path analysis. Using our air conditioning/acoustics test benches, which we developed in-house, we are able to meet every requirement. Our measuring technology impresses with its modular system structure, fast sampling rates, ultra-precise analogue/digital conversion as well as integrated measuring bridge completion. We can also perform acceleration measurements with IEPE support.

Weight reduction with increased safety

In light of increasingly strict emissions requirements as well as increasing demands for system efficiency, many systems must "slim down" while still ensuring the strict safety requirements are always met. This is a particular challenge in chassis development. The demands on data logging and evaluation during development are accordingly high. With our expertise and measuring technology, we are able to find the optimal solution to your requirements.

Climate Acoustic Chamber

The climate-acoustic chamber with its flexible conditioning from cold to heat climate offers ideal boundary conditions to realistically load the heating/air conditioning system of a vehicle. With the control of the temperature from -20°C to +50°, the humidity, the sun simulation by means of infrared lamps as well as the vehicle inflow with up to 32 km/h driving wind, a variety of climate zones can be simulated as vehicle environment. In addition to the thermodynamic usability, the design as an acoustic semi-free-field room together with the hydrophobic attenuation of all conditioning components allows the authentic evaluation and measurement of acoustic phenomena. Typical applications include the testing and subjective evaluation of in-vehicle air conditioning compressors, HVAC noise (evaporator hiss) and general transfer path analysis of the refrigeration circuit.

Services with the Acoustic Camera

As is well known, multi-channel microphone measurements allow the evaluation of sound propagation at different positions. This allows conclusions to be drawn about different assemblies and their acoustic radiation behavior. However, the spatial resolution when using conventional microphones is limited and the exact assignment of where a sound is actually emitted is often very inaccurate. Here, the use of the acoustic camera offers a practical and fast possibility for the identification of dominant partial sound sources. Using a ring-shaped arrangement of 48 individual microphones (microphone array) and a video camera in the center of the ring, the sound radiation is initially recorded synchronously with the video image data. The analysis of the different propagation times of the sound radiation of individual partial sources allows the directional assignment of their radiation points.

Acoustics Simulation

The acoustic development of automotive components benefits significantly from the interaction of testing and simulation. While general experience and analyses of measurements form the basis for new developments, simulation allows the evaluation of components and concepts in advance, independently of time- consuming and cost-intensive hardware. Thus, it is possible to select from several designs, weak points can be identified and avoided at an early stage. Thus, the parallel management of simulation and testing allows a constant mutual optimization - the quality of each hardware construction stage benefits from the previous simulation; likewise, the accuracy of the simulation models can be optimized by comparison with the subsequently available measurement data.
