modelMass

Sliding mass with inertia

Extends from Translational.Interfaces.PartialRigid (Rigid connection of two translational 1D flanges).

Information

Sliding mass with inertia, without friction and two rigidly connected flanges.

The sliding mass has the length L, the position coordinate s is in the middle. Sign convention: A positive force at flange flange_a moves the sliding mass in the positive direction. A negative force at flange flange_a moves the sliding mass to the negative direction.

Parameters

TypeNameDefaultDescription
SI.MassmMass of the sliding mass
SI.LengthL (from PartialRigid)Length of component, from left flange to right flange (= flange_b.s - flange_a.s)

Connectors

TypeNameDefaultDescription
Flange_aflange_a (from PartialTwoFlanges)(left) driving flange (flange axis directed into cut plane, e. g. from left to right)
