Our testing experts are experienced engineers in planning, developing and building tailored test beds for a wide variety of applications.
Beside the construction of non-standard testbeds our core competences covers:
Batteries play an ever-increasing role in the vehicle development. Therefore, it is important to understand the potential risks involved with these devices. At this test bench we can investigate the thermal runaway characteristics of different types of batteries at different conditions.
The battery tests are performed either on a complete battery — called a pack — or on one or more cells that make up the battery. Simulating and integrating models therefore allows the cell’s full environment to be considered.
SCR is one of the technologies that is able to help flattening nitrogen oxide emissions. It injects a mixture of water and urea (AdBlue) into the exhaust tract. This reduces the NOx share in exhaust fumes. VIRTUAL VEHICLE engineered a SCR test bed that can measure remains and the conversion rate of the selective catalytic reduction.
The climatic chamber offers the possibility for testing the aerodynamical and thermodynamical behaviour of air conditioning and heat pumping systems and their components. Furthermore, the design allows calorimetric measurements.
Multi-axis vibration testing improves test efficiency and increases test confidence by applying realistic vibration environments. Therefore we develop NVH tests to bring together the requirements of OEM and supplier. Multi-axis NVH component testing gives a good prediction of the perception in real vehicle. Component non-linearity and complex motions in real vehicle can be assed and gives input to NVH simulation model.
FRIDA is the in-house developed friction dynamometer test bench for engines that allows in an economical way to measure highly accurately the friction power losses in engines for all operating conditions of interest (load and speed).
In addition to its superior accuracy, it further allows to determine also the friction power losses of the subsystems piston assembly, journal bearings of the crank train and the valve train for these operating conditions.
The heat rejection and inner pressure loss of radiators and charge air coolers can be measured on the cooling component test bed. The key parameters are:
The wind tunnel offers a wide range of applications, like testing of cooling packages and determination of characteristic curves of fans, as well as aerodynamic investigations of the vehicle front end or other components by means of Laser-Doppler-Anemometry (LDA). Besides the mentioned investigations for the automotive field, it is also possible to conduct measurements, for instance, to determine the statical and dynamical behavior of bridge models.
