An identical value is output to the connections Stroke1 and Stroke2 as well as to the connections Velocity1 and Velocity2 in each case. The connections are available in order to
simplify the model structure.
For further simplification of the model structure, the component has the mechanical connectors Mech1 and Mech2, with which the variables Force1 and/or Force2 as well as
stroke and velocity can be transmitted summarized.
The total mass which is moved is the sum of Mass and AdditionalMass. With the Orientation, the movement plane can be sloped in any angle to the horizontal. The resulting force
due to gravity is considered automatically.
The friction force is computed in accordance to the Stribeck curve. The parameters
BreakawayFrictionForce, MixedFrictionForce, SpeedMixedFriction, and the ViscousDamping
represents the characteristic values shown in the figure. The friction is not influenced by
the inclination of the movement plane.
The friction is also definable with a look-up table (Ffriction(v). If a table is selected it will be
used, if not, the normal parameters for the friction description are used. The look-up table
is defined in one quarter only for positive velocity include 0. The component calculates
with the absolute value.
