In this study, the methods that simulate mechanical phenomena with high fidelity are pursued so that the simulation is utilized to predict real world. The following topics were studied, 1) development of the simulation method based on the subordinate structure. 2) construction of the human body modelfor the simulation. We proposed a new model for clothing simulation in which a fabric was modeled as a structure of threads. An editor to define virtual threads and to weave them into a fabric was made. A program for the mechanical calculation was also made. The shape of a fabric was obtained as the minimum potential state. We compare the theoretical solution and the result of the simulation for verification of the validity of the program, and they agreed very well. In the simulation, it is necessary to detect collisions between threads because the collisions occur during the mechanical calculation. The function to detect collisions was included in the simulation program. The amount of the calculation was greater than that based on conventional models, we tried to process with the method of parallel operations. We developed a method to estimate inner structure of human body. A program to reconstruct a surface shape from the boundaries of many images of cross section was made, and a sUijace shape of human body was reconstructed with the program. It was adapted to another swjace shape of human body which was measured with a 3-D shape measurement instrument. The inner part was deformed with the adaptation. The estimation was obtained as the deformation of the inner part. The inner structure of right arm was estimated and there was some error for the estimation. We also investigated the structure and functions of backbone, and then developed a mechanical simulation program based on a very simple model of backbone., Article, 文部科学省2 1世紀COEプログラム「先進ファイバー工学研究教育拠点」研究成果報告書13:277-278(2007)}, title = {15-7-7 : 柔軟物シミュレーションの高度化に関する研究}, year = {2007} }
