摘要：

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.
