Efectos de la inserción de elementos de parámetros concentrados sobre los modos normales de oscilación de un medio finito continuo

Abstract

In this work, the influence of lumped parameters on the normal oscillation modes of mechanical systems are studied theoretically. In particular, we study the vibration modes of a dipole antenna with concentrated inductances and a tube with an expansion chamber inserted in its middle point. It is found that these problems have close similarities with the transverse modes of a homogeneous string fixed at both ends and loaded with one mass at its middle point.
