Illustrazione opzionale qui in mezzo?(meglio se su fondo bianco)

Slide 2

Introduzione

  • Nota: allego una dozzina di slide come esempio di PPT con foto/etc.

  • Multiple clearances: a numerical challenge…

  • Dry friction model

  • Rigid body assumption

  • Formulation as vector-measure differential inclusions

  • Solution by means of Second-Order Cone Complementarity Problem

Slide 3

Introduzione

  • Clearances with dry friction sometimes are unavoidable:

  • Cheap devices:

    • Printers

    • Home appliances

  • Sturdy, rough mechanisms:

    • firearms,

    • earth-moving machines

    • harvesting machines

Slide 4

Known approaches

  • Smooth ODE with deformable kinematic pairs

  • (ex. Hertz theory, FEM, regularization, etc.)

  • Problems:

  • - computationally expensive

  • - knowledge of material/geometry

  • Non-smoothdynamics with

  • piece-wise integration

  • (stop-and-restart schemes)

  • Problems: multiple contacts?

Slide 5

Our approach

  • Assumptions:

  • - multi-rigid-body model

  • - N point-like contacts in clearances

  • - Coulomb dry friction model

  • Kinematic pairs with clearances: set of unilateral contacts with friction

Slide 6

Revolute joints

  • In three dimensional case:

Signorini’s complementarity condition

Slide 7

Prismatic joint

  • For the three dimensional case, at most 16 unilateral contacts

For all the edge-pairs, (l1, e4) (l1, e1) (l2, e1) (l2, e2) (l3, e2) (l3, e3) (l4, e3) (l4, e4) (l1, e8) (l1, e5) (l2, e5), (l2, e6) (l3, e6) (l3, e7) (l4, e7) (l4, e8) :

Slide 8

Contact model

  • For each contact pair:

  • Vectors w and u

  • from Gram-Schmidt

  • Friction force:

  • Coulomb friction as maximum-dissipation principle (from Kuhn-Tucker form):

Slide 9

Eccetera eccetera…

  • Modificare / inserire slide a piacimento

    • Usare liste con punti tipo questa quando possibile

    • Preferire immagini a descrizioni testuali

    • Meglio tante slide semplici piuttosto che poche complesse

  • Eccetera eccetera

    • Bla bla

    • Etc.

Slide 10

Conclusioni

  • Pochi punti qui.. (sintetizzare principali conclusioni)

  • Bla bla…

  • Bla bla…

  • Bla bla…

  • Bla bla.
