Summary :

|
ABSTRACT. IN THIS WORK IT IS INVESTIGATED A PARTICULAR SYSTEM CONSISTING OF A PENDULUM WHOSE POINT OF SUPPORT IS VIBRATED ALONG A HORIZONTAL GUIDE BY A TWO BAR LINKAGE DRIVEN FROM A DC MOTOR, CONSIDERED AS A LIMITED POWER SOURCE. THIS SYSTEM IS NONIDEAL, SINCE THE SPEED OF THE MOTOR IS INFLUENCED BY THE RESPONSE OF THE SYSTEM, REVEALING A VARIETY OF NONLINEAR PHENOMENA. THE BIFURCATIONAL BEHAVIOR IS COMPLEX MAINLY NEAR A SECONDARY RESONANCE REGION, WHERE THE ESCAPE PHENOMENON IS OBSERVED. DURING PASSAGE THROUGH THE CRITICAL SPEED, AN IMPORTANT CHARACTERISTIC APPEARS, WHERE THE SYSTEM MAY PASS THROUGH THIS REGION REACHING A LIMITED ATTRACTOR OR IT MAY ESCAPE FROM THE POTENTIAL WELL TO A REMOTE ATTRACTOR.
KEYWORDS: NONIDEAL SYSTEM, PENDULUM, ESCAPE.
