Numerical Simulations and Design Calculations
About
When developing new instruments and processes for excellent science, the limits of what is feasible are often reached. This development requires careful design and optimisation of components that are exposed to extreme loads during operation and processes that are decisive for the success of the subsequent scientific experiment. Using modern simulation methods, we can evaluate concepts in advance, determine important influencing factors and detect development errors or weak points at an early stage. This helps to save time and money. Complex test series are avoided or reduced by our computer simulations. At the same time, we calculate effects that are difficult or impossible to measure.
In our simulations, for example, we determine stresses and vulnerable component areas. We determine the vibration behaviour and critical natural frequencies, calculate temperature and magnetic fields or simulate complex flow processes. Whether enormous heat, vacuum or high pressure, particle interactions, high rotational speeds or even bird strike - we ensure that the components and instruments we develop perform reliably in research. In particular, components that will later be exposed to extreme loads are efficiently planned and optimised by our team on the computer. Manufactured according to our specifications, they then fulfil their task reliably and trouble-free in daily operation.
