The purpose of this study is to investigate influences of human's mental workloads on a human-mechanical vibration system. The one-degree-of-freedom mechanical structure involving a human body standing on it is considered. The human body and the mechanical structure are modeled as a linear two-degrees-of-freedom coupled vibration system, and the parameters of a human body, such as a mass, a damping coefficient and a stiffness coefficient are identified from the experimental frequency response for the vertical excitation. The cases with two kinds of mental workloads are investigated experimentally, and the relationships between them and the changes of the identified human model's parameters are discussed.
