Class Documentation#

class GearedCompoundBody : public Karana::Dynamics::CECompoundBody#

Constraint embedding class for a body pair connected by a gear.

This class is for a parent/child body pair with 1 dof hinge with a gear ratio relating the outboard body hinge coordinates to those of the inboard body. The inboard body coordinates are treated as the indepedent coordiantes.

Public Functions

virtual ~GearedCompoundBody()#

Destructor.

inline virtual const std::string &typeString() const noexcept override#

Returns the type string of the SubTree.

Returns:

The type string.

GearedCompoundBody(const std::string &name, kc::ks_ptr<SubTree> parent_subtree, kc::ks_ptr<SubTree> bodies_tree)#

Constructs a GearedCompoundBody.

inline void setGearRatio(double gear_ratio)#

Public Static Functions

static kc::ks_ptr<GearedCompoundBody> create(kc::ks_ptr<SubTree> parent_subtree, const std::string &name, kc::ks_ptr<SubTree> component_bodies)#

Protected Functions

virtual void _updateDependentQ(const km::Vec &min_Q) const override#

Convert the input minimal coords Q into the full dependent Q for all the aggregated subhinges for the compound body

virtual km::Mat _constraintX() const override#

Convert the input full dependent coords for all the aggregated subhinges for the compound body Q into the minimal independent Q Return the X matrix that maps the min independent U to the full dependent U for the compound body

virtual km::Mat _constraintXdot() const override#

Return the Xdot matrix that is the time derivative of the X constraint matrix

virtual km::Mat _invConstraintX() const override#

Return the X matrix pseudo inverse that maps the full dependent U for the compound body to the min independent U

virtual kc::ks_ptr<CoordData> _makeIndependentCoordData() override#

Create a CoordData with just the CoordBased with the independent coordinates for this body

Protected Attributes

double _gear_ratio#

the ratio of the outboard subhinge coords rate to that for the inboard subhige
