Development of a soft dummy which has distributed material properties of human body surface

前川, 佳徳  ,  津田, 惇司

Description
Soft dummy of human body having more real and low cost is required for nurse and care training. Most soft human dummies have an uniform material of body surface. In this study to develop a soft dummy which has distributed material properties of human body surface is proposed. Distributed hardness of real human body surface is measured and is corresponded to selected 6 grades hardness of polyurethane materials. To produce a soft dummy having 6 kinds of materials has much difficulty. Then, material properties( elastic constants) of 6 grades of polyurethane are replaced by each equivalent structures with many small air space inside using one grade of polyurethane. To obtain elastic constants of selected 6 grades of polyurethane, an experiment and FEM simulation are proposed. To determine the above proper structures by using of one grade for 6 grade materials of polyurethane, the same experiment and FEM simulation are available. The soft dummy offered in this report can be produced by an additive manufacturing.
