概要:

application/pdf<br />Journal Article<br />In this report, the transient vibrations of a beam mass system subjected to nonlinear electromagnetic force are investigated theoretically and experimentally in consideration of both the nonlinearity of the electromagnetic force and the inductance of a electromagnet. The beam is fixed at one end, and the mass is attached to another end. The electromagnetic force produced by the elctromagnet … acts on the mass. The electromagnet is excited by sinusoidal waves, rectangular waves and rectangular pulse voltages by using a micro computer. In the analysis, the electromagnetic force is approximated by using a series of rectangular pulses, and the lateral vibrations of the beam are obtained by adding the individual responses due to each rectangular pulse. The response solution of the governing partial equation of the beam mass system is derived by the Laplace transformation method. The numerical results agree well with the experimenatal ones. 続きを見る
