Member Function Documentation

◆ GetGuideBoxDimensions()

virtual const ChVector& chrono::vehicle::m113::M113_TrackShoeBandBushing::GetGuideBoxDimensions ( ) const
inlineoverridevirtual

Return the dimensions of the contact box for the guiding pin.

Note that this is for contact with wheels, idler, and ground only. This contact geometry does not affect contact with the sprocket.

Implements chrono::vehicle::ChTrackShoeBand.

◆ GetType()

virtual GuidePinType chrono::vehicle::m113::M113_TrackShoeBandBushing::GetType ( ) const
inlineoverridevirtual

Return the type of track shoe (guiding pin).

A derived class must specify the type of track shoe (which must be consistent with the idler and road wheels in the containing track assembly).

Implements chrono::vehicle::ChTrackShoe.

◆ GetWebInertia()

virtual const ChVector& chrono::vehicle::m113::M113_TrackShoeBandBushing::GetWebInertia ( ) const
inlineoverridevirtual

Return the moments of inertia of the web.

These will be distributed over the specified number of web segments.

Implements chrono::vehicle::ChTrackShoeBand.

◆ GetWebMass()

virtual double chrono::vehicle::m113::M113_TrackShoeBandBushing::GetWebMass ( ) const
inlineoverridevirtual

Return the mass of the web.

This will be equally distributed over the specified number of web segments.

Implements chrono::vehicle::ChTrackShoeBand.
