The new component or structural design process is increasingly subjected to more virtual prototypes in place of real prototypes. This current process not only encompasses simple structural calculations of static stresses using finite elements, but it also requires properly simulating load creating processes (multi-body models), the dynamic effect of said processes on the components (finite elements) and consequences in regards to comfort (acoustics) and durability (fatigue). We, at Aresse, are experts of all these procedures.

Finite element simulations are the base for making dynamic predictions, which then translate into vibrations and noise. Generally, it is possible eliminate the effects of amplification that occur when a component is working in a dynamic system. These effects are extremely important in regards to acoustics and durability alike. Aresse has profound knowledge on the dynamic behavior of systems, how to simulate them and, above all, on how to prevent the effects of such behavior.

On one hand, dynamic vibrations are transmitted to the fluids, surrounding them, in turn producing sound. On the other, the dynamic forces exerted by fluids on the solids they surround, are converted into vibrations, which can in turn translate into internal sound.

It is very useful to simulate acoustic processes, as these simulations shed light on the environmental acoustic pressures, which are not intuitive. It also permits visualizing the acoustic interaction with different structures and components and precisely studying the effect of these interactions.

The effects of dynamic amplification, suffered by components when they are submitted to time and frequency dependent loads, can cause the fatigue loads to grow by several orders of magnitude. Generally, these amplification factors are taken into consideration by using safety factors.

In a world that is ever growing more competitive, these safety factors are highly inefficient. Therefore, the useful life of a component should be predicted in such a way that the dynamic load amplification (or reduction) factors are taken into consideration, since the dynamic force is always in the medium. Aresse masters these simulation techniques and improvement design procedures.

Multi-body systems permit us to gain an understanding of the dynamic loads acting on different components in a system. The movement of solids comprising the system considered in conjunction with their inertia, the external forces acting on them, etc. create force vectors that the different components must support. These forces, where they cause vibration, amplification, etc. are input into the finite element models, which permit calculating the durability of components or acoustic emissions. The multi-body models are also extremely useful in the design of automatic control systems, as these are used to precisely preset the parameters for the regulators that control a dynamic system.

Along those lines, Aresse is capable of simulating any dynamic system, including control systems, so as to obtain precise regulator parameters as well as the dynamic forces supported by the currently controlled system.
