In mechanical designs much attention is to be paid to human beings from the standpoint of comfort and safety. Once the dynamic characteristic model of human body is built, the effect of vibration can be evaluated in various conditions. Since the spinal column is the main transfer path of vibration from the sheet, the model has a structure of the spinal column with the head. This paper presents a simplified model of sitting human body with the spinal column. The model is constructed so as to have the smaller number of degrees of freedom (DOFs) than the actual spine. Number of DOFs is determined in order to express the dynamic behavior of human in the frequency range of interest. The model parameters are searched so that the transmissibility of the model get agree well with experimental result. Further application of the model such as the load evaluation inside the spinal column is also examined.
