The use of simulation solutions and modeling increases the effectiveness of development processes. In the early stages of product development, virtual models replace complex design patterns and prototypes, enabling flexible and effective system testing and troubleshooting. This shortens development times and lowers development costs. senetics Product Development offers support in the introduction and use of simulation techniques.

We offer in the field of modeling & simulation

  • Creation of a system model
  • Parameterization of the model
  • Determination of the model parameters with the help of test series
  • Simulation and optimization

Modeling

A distinction is made between structural and pragmatic modeling. In structural modeling, the internal structure of the system is known, but it is deliberately abstracted, modified, and reduced. This is called a white box model. In pragmatic modeling, the internal structure of the system is unknown; only the behavior or interaction of the system can be observed and modeled. The backgrounds are usually not or only partially understood – this is called a black box model. In the course of modeling, the object is reduced by delimitation and prepared for the simulation.

Depending on your needs, senetics uses these methods to model your problem. Therefore CAD data is often created, which can be used for FEM simulations.

With the help of the simulation of physical effects different influences on the product can be investigated. In addition to linear static strength analyzes, non-linear calculations and stationary thermal and thermomechanical analyzes as well as natural vibration analyzes can also be carried out.

Using stationary thermal finite element analysis, we can perform an analysis of the thermal behavior of your product at each stage of development. By coupling thermal and mechanical boundary conditions, thermo-mechanical displacements or stresses can be calculated in addition to the thermal results, such as temperature or heat flow. This ensures that the temperatures for each component during operation are within the permissible temperature ranges. Any security problems that arise are thus revealed in advance and can be eliminated at an early stage of product development.

The linear static analysis of individual components has long been part of day-to-day business in today’s simulation tasks. However, the previously isolated consideration of individual components is often not realistic due to the lack of interaction with neighboring components. Using a contact simulation, components can be simulated in the network.

With senetics, the following effects can be investigated and simulated

  • Tensile and compressive stress (stress analysis)
  • Heat or cold propagation
  • Contact simulation (glued, frictionless)
