All branches of industry make use of complex mechanical systems, most of which usually contain a number of moving compnents. To ensure that individual components interact with one another in an optimum way right from the development stage, TECOSIM engineers use multi body system simulation.
In multi body system simulation, all elements involved in the process are transformed into rigid bodies in a model. This relatively simple model allows the engineers to calculate the behaviour of individual components during a movement. Different aspects are taken into account during a multi-body system simulation and analysis: masses, moments of inertia, active forces and moments, and the interlink and contact conditions of individual (rigid body) elements. The model simulation produces (oscillating) movements and (mass) forces. The data acquired from the simulation can be used to further optimise system components and their interaction.
Multi body system simulation is mostly used in combination with other studies as it not only provides simulation of kinetic behaviour, but also shows the loads for individual components. The results from a multi body system simulation are incorporated into a stress analysis with the aid of FE analysis, for example.
