We have presented a vibration system subjected to a horizontally asymmetric two-well potential type restoring force. The linear spring is installed perpendicularly to the direction of excitation. In addition, the guide way of the oscillator has an angle to the vibration direction. The chaos vibration characteristics in this system under sinusoidal excitation have clarified. In this study, we examine the chaotic vibration characteristics of the system under non-sinusoidal excitation. The periodic waveform created by using the originally presented map function applies to the excitation waveform. From the numerical analysis results, it is found that the period doubling bifurcation-chaos occurs by the varying of the excitation waveform shape.
