Outline of Final Research Achievements

Seat comfort is usually tested by research participants. However, in this test, results show dispersion and the cost is expensive. Therefore, research to find alternative method is attracting attention. Development of human dummy for ride comfort was reported, however it can reproduce the human comfort characteristics only with low frequency range. In this study, to develop human dummy reproducible for wide frequency range, we proposed a new dummy composed of a flexible membrane filled with viscous liquid called aqua dummy. First, we proposed design method of aqua dummy and secondly showed the validity of proposed method by experiments. In the design method, fluid structure interaction was taken into account. In the experiment, we designed and manufactured small size aqua dummy and measured frequency response and compared with the result calculated based on the proposed method.
