Constructor & Destructor Documentation

◆ ChTrackShoeDoublePin()

chrono::vehicle::ChTrackShoeDoublePin::ChTrackShoeDoublePin ( const std::string & name )

Parameters

[in] name name of the subsystem

Member Function Documentation

◆ ExportComponentList()

void chrono::vehicle::ChTrackShoeDoublePin::ExportComponentList ( rapidjson::Document & jsonDocument ) const

overrideprotectedvirtual

Export this subsystem's component list to the specified JSON object.

Derived classes should override this function and first invoke the base class implementation, followed by calls to the various static Export***List functions, as appropriate.

Reimplemented from chrono::vehicle::ChPart.

◆ GetPitch()

double chrono::vehicle::ChTrackShoeDoublePin::GetPitch ( ) const

overridevirtual

Return the pitch length of the track shoe.

This quantity must agree with the pitch of the sprocket gear.

Implements chrono::vehicle::ChTrackShoe.

◆ Initialize() [1/2]

void chrono::vehicle::ChTrackShoeDoublePin::Initialize	(	std::shared_ptr< ChBodyAuxRef >	chassis,
		const ChVector<> &	loc_shoe,
		const ChQuaternion<> &	rot_shoe,
		const ChVector<> &	loc_connector_L,
		const ChVector<> &	loc_connector_R,
		const ChQuaternion<> &	rot_connector
	)

Initialize this track shoe system.

This version specifies the locations and orientations of the shoe body and of the connector bodies (relative to the chassis frame).

Parameters

[in]	chassis	handle to chassis body
[in]	loc_shoe	location of shoe body
[in]	rot_shoe	orientation of shoe body
[in]	loc_connector_L	location of left connector body
[in]	loc_connector_R	location of right connector body
[in]	rot_connector	orientation of connector bodies

◆ Initialize() [2/2]

void chrono::vehicle::ChTrackShoeDoublePin::Initialize	(	std::shared_ptr< ChBodyAuxRef >	chassis,
		const ChVector<> &	location,
		const ChQuaternion<> &	rotation
	)

overridevirtual

Initialize this track shoe subsystem.

The track shoe is created within the specified system and initialized at the specified location and orientation (expressed in the global frame). This version initializes the bodies of a double-pin track shoe such that the center of the track shoe subsystem is at the specified location and all bodies have the specified orientation.

Parameters

[in]	chassis	handle to the chassis body
[in]	location	location relative to the chassis frame
[in]	rotation	orientation relative to the chassis frame

Implements chrono::vehicle::ChTrackShoe.
