This paper deals with experimental and analytical study of free rocking response and analytical of rocking due to harmonic shaking.An equation of motion of rigid brock of free rocking is built.This equation of motion changes into the non-linear equation.Numerical analysis based equation of free rocking is conducted.Experiment of free rocking is conducted and experimental result and numerical-analysis result are compares.Thus optimal coefficient of restitution is presumed.An equation of motion of rigid brock of rocking vibration induced by base excitation is built.This equation of motion changes into the non-linear equation.Numerical analysis based this equation of motion is conduct.From numerical-analysis result of various excitation amplitude and pitch,consideration of response characteristic of rigid block of rocking vibration induced by base excitation.It is concluded that grasp of optimal coefficient of restitution and characteristic of rigid block of rocking vibration induced by base excitation amplitude and pitch is possible.
