ITI SimulationX Libraries

MECHANICS Libraries

The SimulationX Mechanics libraries – Linear Mechanics, Rotational Mechanics, and 3D Mechanics - provide efficient means for solving tasks from mechanical engineering, such as the modeling and simulation of drive systems. The element types in the libraries allow a fast and trouble-free assembly of simulation models. The terminology and the symbols, which are used in these libraries, are common in engineering and thus well comprehensible. A model is assembled from fundamental mechanical components – masses, inertia, spring-dampers, forces, etc. Parameters are for instance moments of inertia, stiffnesses and dampings. Displacements (or angles), velocities, accelerations, and internal forces (or torques) are the typical result quantities of the components. Thus the mechanical engineer can model and simulate in a framework, which he is used to. There is no need to formulate differential equation systems or to transform the system under study into an abstract signal oriented block structure. The element types in the Mechanics libraries consider statics, kinematics, and dynamics in 1D and 3D mechanical systems.

 

Model libraries for 1D, 2D and 3D Mechanics with consideration of statics, kinematics and dynamics

Multibody system analysis with rigid bodies and CAD import

Flexible choice of mechanical parameters (stiffness, damping, friction, backlash)

Free definition and consideration of constraints (displacement or velocity difference or default function)

Elastic and rigid friction with input of the conditions

Modeling of elastic and rigid end stops with choice of impact type (plastic, elastic) or impact factor

Libraries

The Mechanics libraries contain the following element types:

 
 
The Linear Mechanics and Rotational Mechanics libraries provide the core functionality for one- dimensional mechanical systems. Parameters can be also specified in terms of characteristic curves or expressions and components can be combined into new model objects (compounds). So even complex mechanical systems, such as a vehicle powertrain or a machine drive, can be handled very easily. All element types from the mechanics libraries can be used in combination with the elements from the Power Transmission libraries. The 3D Mechanics library provides a collection of element types for the modeling of kinematical structures. The modeling of closed-chain structures is possible. By importing data from CAD tools bodies with arbitrarily complex shapes can be integrated into the model. Interface elements ensure, that in one single simulation model the 3D structures can be combined with subsystems from other domains (e.g., Linear Mechanics, Hydraulics, or Controls). The integrated 3D view provides a comfortable environment for modeling, visualization and observation during simulation, as well as for the animation after a completed simulation. The SimulationX name space concept allows the implementation of fully parametric models.
