Title:
|
A CRITICAL ANALYSIS OF MODELS OF COLLISIONS BETWEEN RIGID BODIES
|
| |
|
Summary :
|
|
IN MODELING COLLISIONS BETWEEN RIGID BODIES IT IS DIFFICULT TO CONSTRUCT A MODEL SUFFICIENTLY SIMPLE THAT PERMITS THE SIMULATION OF A PROBLEM IN REAL TIME AND SO SOPHISTICATED TO REPRESENT WELL THE DYNAMICS. THE AIM OF THIS PAPER IS TO DESCRIBE SOME OF THE MODELS MORE USED AND TO COMPARE THEM USING NUMERIC SIMULATIONS AND TO SHOW ITS LIMITS OF VALIDITY. TO UNDERSTAND WHAT IS HAPPENING WE SHOW ANIMATIONS, USING THE GRAPHICAL USER INTERFACE OF MATLAB. THE MODELS COMPARED ARE : NEWTON S LAW COMBINED WITH COULOMB S LAW, POISSON S LAW COMBINED WITH COULOMB S LAW, FR\ EMOND S MODEL WITH COULOMB S LAW AND FR\ EMOND S LAW WITH VISCOUS FRICTION.
KEY-WORDS: COLLISIONS, DYNAMICS, SIMULATION}
