 note = {流体と剛体/弾性体の連成シミュレーションはコンピュータグラフィックスの分野で大きな課題の1つである．本論文では，物体の大変形を容易に扱うことができる粒子ベースの計算モデルを用いた伸縮変形体―流体連成シミュレーション手法を提案する．本手法では，SPH法による流体シミュレーションとバネマスモデルによる伸縮変形体シミュレーションを連成して計算を行う．バネの距離に応じて粒子が保持する密度の閾値を変化させることにより，近傍粒子が密になるときは粒子径を小さくし，逆に疎になるときは粒子径を大きくするというような計算と同等の効果が得られ，粒子法の大きな問題点の1つである物体が膨張したときの粒子のすり抜けを起こりにくくすることができる．本手法を用いて，伸縮によって様々に密度変化する物体と流体との連成をシミュレーションすることができた．, The coupling simulation of fluid and rigid/elastic body is one of the most important problems in the field of the computer graphics. In this paper, we propose a simulation method of coupling of fluids and telescopic deformable bodies with particle-based manner which is easy to deal with large deformation of objects. When we calculate coupling of them by the proposed technique, we use the SPH method for simulating fluids and use a mass-spring model for telescopic deformable bodies. In our method, the density threshold values of the particles are changed according to connected-spring distance, and that is equal with calculation that the particle diameter is reduced when the neighboring particles become dense and the diameter is enlarged when becoming sparse oppositely. Hence we can inhabit penetration between particles which is one of the most crucial problems of particle-based simulation when the object is expanded. We succeeded in simulating coupling of fluids and objects which are changed the density by being contracted and expanded.},
