Mechanics


The Mechanics library and its sublibraries provide model objects which are tailored to the modeling of mechanical systems, allowing the solution of tasks in this area as efficient as possible. Symbols and notions are oriented on mechanical engineering. Simulation models are assembled from translatory and rotary masses, spring-dampers, force sources, etc. Inertia, stiffness and damping constants are typical parameters. As simulation results the user has access to forces (or torques respectively), displacements (or angles), speeds, and accelerations. A mechanical engineer can conveniently describe a system under study in the way he is used to it. There is no need to formulate equations of motion or to transfer the problem into a signal-oriented description (block structures) before modeling.

The following sublibraries are included in the Mechanics library:

Linear Mechanics (1D)
Rotational Mechanics (1D)
Planar Mechanics
MBS Mechanics

Each mechanical domain contains elements or models types, resp., for the representation of body contacts. The following linked chapter contains the common basic knowledge of these planar (2D) contact models, which are applied in the several Contact Elements model libraries.

Contact Models

The Linear Elastic Structure contains the Modal System, which will be created as a Local Type in the active model. To create Modal Systems as Local Types, go to menu Insert -> Modal System....

To import the results of a finite element analysis of a three-dimensional mechanical structure go to menu Modeling -> Insert -> FEM Import.
