流動解析シミュレーションの転写性による検討

抄録

In　quality　engineering,　non-dynamic　characteristics　have　been　used　for　flow　analysis simulation　in　an　injection　molding　process.　But　in　actual　injection molding　experimentation,dynamic　characteristics　are　used.　Therefore,　there　is　a　lack　of　contrast　for　both　approaches. Recently,　the　WARP　ANALYSIS,　a　simulation　software,　was　developed　to　indicate　the　degree of　deformation　of　an　injection molded　product　by　moving　the　points　which　compose　"product model　mesh".　In　this　paper,　dynamic　characteristic　analysis　was　applied　to　express　the relationship　between　the　input　and　the　output　distances. In　flow　analysis　simulation　for　plastic　injection　molding,　it　is　desirable　to　quantify dimensional　accuracy　or　dimensional　defects　by　a　simple　figure.　The　results　of　this　study showed　that　the　approach　is　useful　to　do　so.
