Aiming to establish a remote generation method of wave in a human body for an inspection of a focus, a remote-vibration exciter is proposed. The exciter consists of a long string and a frame made of thin plates which generates vibrations in a human body. The string transmits vibrations from an electromagnetic vibration exciter to the frame, then bending vibrations are generated in the frame. Furthermore, to establish an analytical procedure solving nonlinear vibrations generated in the frame structure, nonlinear vibrations of a L-shaped beam constrained by an axial spring are analyzed, including non-periodic responses also observed in the experiment.
