Research and Development

Experts at work

Forschung und EntwicklungWe develop special test benches for vibration and noise, tribology and vibration excitation on the basis of your specifications.

Besides, to cement our technology leadership, we are regular partners to government funded research projects.

For instance our core competence "Haptics & Sense" was descended from such a research project.

Currently we are working on the following projects:

Influence of material characteristic by physical parameter like voltage, amperage or pressure.

Short nameInnoShake – Development of a noise test bench with integrated climate chamber in function optimized light-weight design by the consistent use of fiber composite materials for the mechanical and thermal functional assemblies.
AbstractIn the preseries, the noise generating contact points are examined on vibration exciters (shakers) that simulate road profiles. To be able to localize noise, the test environment should be low-noise (max. 30 dB). The electro-mechanical shakers available in the global market meet these noise emission requirements only for excitable mass up to 150 kg. The mass to be excited consists of the weight of the tested assembly and the weight of the test bench. The target of the project is by making consistent use of function optimized light-weight structures with fiber composite materials to reduce the weight of the test bench significantly in favor of the weight of the test load in order to attain  a unique selling proposition in test bench technology. The following detail problems are to be replaced by innovative solutions: Reduction of the frame weight by the use of carbon fiber reinforced plastics, enlargement of the useful amplitude range by stingers of fiber compound plastics, reduction of the complex mechanical design, and development of an innovative climate hood concept for test temperatures between -30 and +80 °C.

Short nameDevelopment of a quick test for the simultaneous testing of several tendons or stay cables on "”soft”" structures.
AbstractThe target of the project is the development of a quick test for the simultaneous testing of several tendons or stay cables on ""soft""structures. Due to the softness of the structures, the tendons or stay cables are exposed to constant vibration so that the measurement of vibrations by suitable sensors that must be developed will be possible without excitation in the way that is practiced today on bridge tendons. By recording and comparing the vibration measurements of several tendons and / or stay cables of a building and their reference to earlier measurements potential changes to the ropes / tendons and the structure can be identified early and possible damage prevented. However, because soft structures vary widely in their design, it is also necessary to develop damage assessment models from defined frequency spectra for stadiums and wind on-shore wind power plants.

Short nameCorrelation of rubbing noise with the material properties of anisotropic materials and human perception.
AbstractNoise caused by rubbing textiles against each other can be pleasant or unpleasant. Most of all in the automotive industry unpleasant noise inside the car is a problem because the complaints they cause mean high cost for the car makers. In other areas, such as the clothing industry, noise and the way it is perceived by people is critical to whether a product will be selling fast. Product design and successful sales require knowledge of the mechanisms generating noise and the emotional effect of noise on humans. The purpose of the research project is the development of the friction device that can measure and evaluate anisotropic surfaces independent of the direction, the assessment of the risk that noise is generated should be part of the analysis. The rubbing signals will be correlated with the acoustic measurements and the assessment of the noise and their psycho-acoustic effect. Another aim is the identification of the causes of the identified and characterized noise and their relation to materials.

Short nameSIMU-SQS simulation and prediction of friction noise of elastomer seals in  vehicles.
AbstractSqueak and rattle still are the great unknowns for designers of seals and gaskets in the CAD phase and also for finding the problem causing contact spots in the real vehicle.  OEMs and suppliers,  seal/gasket and coating suppliers throughout the world have been trying with varying success to master this phenomenon in physical, technical and chemical respect. Squeak and rattle will be found in cars of any class or make time and again. The reason is surely the multitude of influential factors which are based on over 50 different parameters. It is difficult to isolate the main factor for squeak and rattle from these. Whereas the analysis of the different factors is difficult, costly and time consuming in series produced cars, the main factors can be determined by parameter variations on the test bench. The target of the project is the development of a prototype test bench for the realistic simulation of a system of seal between a door and the car body as well as between door and window pane followed by the determination of the main factors responsible for seal creak.

Short nameUltraSynth – ultra-fast SoC-FPGA synthesis for model driven function development 
AbstractAn ever larger number of development projects in the automotive sector and in mechanical engineering focuses on the development of increasingly more complex control algorithms and functions. A modular, flexible hardware architecture that can be used throughout the whole development process builds on SoC-FPGA whose programming is time consuming and error-prone.  This is where the UltraSynth project comes in with a highly innovative solution approach: Instead of the direct programming of the SoC-FPGA, control algorithms are mapped without the use of proprietary synthesis tools. With this approach, based on the data flow graph of the control algorithm and functions, a reconfigurable coarse grain architecture and adapted hardware units are used for fast calculation codes for the SoC-FPGA. This shortens the synthesis of the FPGA from several hours to a few seconds.

Short nameShaker excitation of interior vehicle systems with superimposed braking, acceleration and taking bends
AbstractNoise (squeak and clatter) today are perceived by customers as the worst quality defects inside a car and as such are critical to the passenger’s well-being and the decision to buy. The warranty and goodwill cost amount to between 40 and 50 million € for each vehicle model. In the past, ZINS was able to make important contributions to the prevention, materials management and the testing technology for hardware and created for itself decisive unique selling propositions in the global market. Whereas the excitation of vehicle components such as the instrument panel, seats, etc. by road profiles such as cobblestone or motorway can be handled successfully by low-noise shaker systems today, the additional simulation of braking, accelerating and taking bends is still waiting for a solution.  Braking and accelerating are essential contributors to noise during road drives. Taking bends, e.g., creates transversal forces in the seat and thereby induces rattle. The purpose of this project is to develop a test bench and test method that simulates the braking and bend-taking process during a road drive.
