| Outline of Final Research Achievements |
We investigated materials and dynamic properties for an arm in the care machines to realize safety by analyzing impact responses of the arm contacted to living bodies. We extended our nonlinear complex spring elements in FEM as nonlinear complex contact force element. Using this method, we computed motions to stop a moving object by a human finger when the block collides to the finger with his reaction. By adjusting the even terms in the imaginary parts of the nonlinear complex spring constants, we can simulate the phenomena that deformations proceed faster than the force locally in the relation between deformation and force which appear with precaution or small panic. Further, we tried to improve the performance in impact absorption for the simplified arms of care machines by referring to the bamboo swords which are used in Kendo. We obtained excellent performance in impact absorption effects by using the CFRP arms which cross sections are divided and their parts are bundled loosely.
