초록

In this study, the shrinkage at the artificial skin tissue and temperature characteristics of rubber pole were analyzed by the experimental and numerical method. A artificial skin tissue was produced by using the rigid sponge pad. The impact of tissue was applied by three types of rubber pole. The shrinkage results along the depth of tissue were measured according to the repetition count of impact. When the shape of rubber pole was sphere type, the shrinkage was greatest. The temperature around the pole was highest in the sphere type while that inside pole was greatest in the twine deep sphere type. This is because the pole temperature of twine deep sphere type was transmitted more inside. As a result, the sphere type rubber pole was the most effective because it showed the largest shrinkage and the lowest temperature gradient during impact.
