スプリング破壊

プロパティTYPE1、TYPE2、TYPE 4、TYPE 8、TYPE 13、およびTYPE 25のスプリング破壊は、2つの方法で考慮することができます。
  • 1方向の破壊
  • 多方向性破壊

これは、オプションIfailによって制御されます。プロパティにIfailフラグが設定されていない / 存在しない場合、スプリングに対してデフォルトの1方向の破壊が考慮されます。たとえば、TYPE4にはオプションIfailがないため、1方向の破壊が使用されます。

破壊モデルでは、変位破壊、力破壊、または内部エネルギー破壊を考慮することができます。これは、オプションIfail2によって制御されます。Ifailと同様に、Ifail2オプションがプロパティに設定されていない / 存在しない場合、変位(または回転)破壊モデルが使用されます。

    破壊値を1方向にのみ設定された限度と比較すると、通常、定義された限度よりも小さくなります。この例の場合、引張限度は0.04mに設定され、ねじり限度は0.035radに設定されています。スプリングは、伸び00.0236 < 0.04、回転0.02826 < 0.035で破壊します。これは、引張とねじりの破壊の組み合わせが、破壊円(図 6)に到達するためです。その結果、スプリングが破壊しました(力とモーメントがゼロになります)。
