Mechanical set: definition (structure)
Mechanical set: definition
A mechanical set is defined by:
 a name (and a comment)
 a type of mechanical set
and for the mechanical sets of rotation around one axis and translation along one axis :
 an axis of rotation or translation
 a type of kinematics (= computation mode)
 kinematic characteristics:
 general characteristics
 internal characteristics
 external characteristics
 mechanical stops
Types of mechanical set
Different types of mechanical sets are presented in the table below.
Type  enables the regrouping of the regions corresponding to … 

fixed  the motionless parts 
compressible 
the zone of air in which the moving part is in motion 
rotation around one axis 
the moving parts in rotation around an axis 
translation along one axis 
the moving parts in translation along an axis 
free movement  The free motion is designed to take into account complex motions (excluding translation and rotation movement). This motion is described by a list of positions for the mobile part 
six degrees of freedom  In space, using an orthonormal coordinate system (O,x,y,z), the 6
degrees of freedom are defined as follows:

Types of kinematics
Different types of kinematics (= computation mode) are presented in the table below.
Kinematics (= computation mode) …  

of type …  enables the realization of a computation … 
Multi static 
of multiposition type in Magneto Static application ( parametrized study in Magneto Static application) 
Imposed speed  at imposed speed in Transient Magnetic application 
Imposed position  at imposed position in Transient Magnetic application 
Coupled load

Multiphysics  to be able to coupling the motion with another software (like Activate) 
General characteristics
General characteristics gather following information:
 initial conditions (initial speed and initial position)
Internal characteristics
Internal characteristics gather following information:
 kinematic characteristics relating to the moving part (proper characteristics) (see table below)
Motion  Characteristics relating to the moving part  

rotating  moment of inertia 
resistant torque (formula or 3 coefficients) 
translating  mass 
resistant torque (formula or 3 coefficients) 
External characteristics
External characteristics gather following information:

kinematic characteristics relating to the coupled load (external device)
(see table below)
Motion  Characteristics relating to the coupled load  

rotating  moment of inertia 
resistant torque (formula or 3 coefficients) 
translating  mass 
resistant force (formula or 3 coefficients) 
Mechanical stops
The various mechanical stops are following:
 minimal stop
 maximal stop
