In this paper, the free rocking vibration behavior of one-degree-of-freedom systems is considered for realize the before detection of furniture tipping. First, the sensing module is fabricated using the angular velocity sensor focused on the furniture rocking motion. Moreover, the free rocking vibration experiment was performed using the above sensing module. In addition, the numerical simulation was conducted by 4th Runge-Kutta method. As the result, the measurement signal using the proposed sensing module was good agreement with the numerical simulation. Furthermore, the detection algorithm of the rocking vibration is derived by the correlation coefficient between the measurement signal and the numerical simulation prediction signal of Runge-Kutta method.
