CAE ANALYSIS METHOD AND CAE ANALYSIS DEVICE

To provide a CAE analysis method that reproduces complex behavior of a connection unit between members.SOLUTION: A CAE analysis method performs CAE analysis by modeling an object including a plurality of members (for example, a columnar member 1 and an upper crosspiece 2) connected with each other and a connection unit formed between the plurality of members. The CAE analysis method includes: a modeling process of applying a beam element to the plurality of members to perform modeling based on CAD data of the plurality of given members; a structure characteristics definition process of applying nonlinear spring characteristics to structure characteristics of the connection unit so as to define the structure characteristics based on the CAD data of the given connection unit; and an analysis process of performing strength analysis of the plurality of modeled members and the connection unit whose structure characteristics are defined.SELECTED DRAWING: Figure 9 【課題】部材間の接合部の複雑な挙動を再現したＣＡＥ解析手法を提供すること。【解決手段】互いに接合された複数の部材（例えば、柱部材１と上桟２）と、前記複数の部材間に形成された接合部と、を含む物体をモデル化してＣＡＥ解析を行うＣＡＥ解析方法であって、与えられた前記複数の部材のＣＡＤデータに基づき、前記複数の部材にビーム要素を適用してモデル化するモデル化工程と、与えられた前記接合部のＣＡＤデータに基づき、前記接合部の構造特性に非線形ばね特性を適用して定義する構造特性定義工程と、前記モデル化された複数の部材および前記構造特性を定義された接合部について強度解析を行う解析工程と、を有するＣＡＥ解析方法である。【選択図】図９
