Member Function Documentation

◆ GetBalancerMaxPitch()

virtual const double chrono::vehicle::ChBalancer::GetBalancerMaxPitch ( ) const

protectedpure virtual

Get the rear balancer min/max pitch.

Used only if using a kinematic joint.

Implemented in chrono::vehicle::Balancer, and chrono::vehicle::fmtv::MTV_Balancer.

◆ GetBushingData()

virtual std::shared_ptr<ChVehicleBushingData> chrono::vehicle::ChBalancer::GetBushingData ( ) const

inlineprotectedvirtual

Return stiffness and damping data for the balancer bushing.

Returning nullptr (default) results in using a kinematic revolute joint.

Reimplemented in chrono::vehicle::Balancer.

◆ GetLocation()

virtual const ChVector chrono::vehicle::ChBalancer::GetLocation ( PointId which )

protectedpure virtual

Return the location of the specified hardpoint.

The returned location must be expressed in the subchassis reference frame.

Implemented in chrono::vehicle::Balancer, and chrono::vehicle::fmtv::MTV_Balancer.

◆ Initialize()

void chrono::vehicle::ChBalancer::Initialize	(	std::shared_ptr< ChChassis >	chassis,
		const ChVector<> &	location
	)

overridevirtual

Initialize this subchassis subsystem.

The subchassis is initialized by attaching it to the specified chassis at the specified location (with respect to and expressed in the reference frame of the chassis). It is assumed that the subchassis reference frame is always aligned with the chassis reference frame.

Parameters

[in]	chassis	chassis
[in]	location	location relative to the chassis frame

Implements chrono::vehicle::ChSubchassis.
