Representation of component connections Between the child structures of an active structure. Between a child structure of the active structure and a structure that does not belong to the active structure. Structures are repositioned according to their parent structure. Connection types Constraints Reference entities Rigid Spherical Cylindrical Planar Prismatic Revolute Screw Point Curve Point Surface Gear Rack Cable Universal Roll Curve Slide Curve Fix Free Symmetry Projection. Contact Fix Coincidence Offset Angle Parallelism Perpendicularity Curve Curvilinear distance Roll Slide Symmetry Coupling Axis system Circle Cone Curve Cylinder Vertex Edge Face Line Plane Point Product Contour Sphere Surface Topological structures are connected László Horváth UÓ-JNFI-IAM http://users.nik.uni-obuda.hu/lhorvath/
Multidisciplinary engineering structure Board form features can be created before or after definition of the board behavior on geometry. Circuit board behavior Electrical component behavior László Horváth UÓ-JNFI-IAM http://users.nik.uni-obuda.hu/lhorvath/
Constraints in connection of shapes Constraint mode Driving: constraint drives constraints which are contextual with it. Measured: constraint value comes from its definition and other constraints of the engineering connection. Controlled: defines the constraint controlled by kinematics relation. The constraint value is defined between bounds. Controlled constraint László Horváth UÓ-JNFI-IAM http://users.nik.uni-obuda.hu/lhorvath/
Degrees of freedom (DOF) Simple joints: Revolute, 1R Prismatic, 1T Cylindrical, 1T+R Screw, 1T+R, constrained Universal, 2R, Spherical, 3R. Curve and surface defined joints Slide along and roll around curve , 1T+1R Slide along, roll around és roll, 1T+2R Planar, 2T+1R Point on curve, 1T+3R Point on surface, 3R+2T László Horváth UÓ-JNFI-IAM http://users.nik.uni-obuda.hu/lhorvath/
Constraint set for given type of connection Set of constraints are defined for placing of solid body with required number of DOFs. In this case, DOF=0 Body which can move 1 translation Coincidence of two surfaces mapped to faces. Coincidence of two lines mapped to edges.
