【iSolver案例分享28】吸力桶(Suction caisson)的力学性能测试
1. 模型背景
该模型为3维模型,为海洋岩土工程中吸力桶的力学性能测试。吸力桶在海洋岩土工程中应用广泛,例如用于支撑海上风机,用以船舶系停,用以安装平板锚等。
吸力桶(Suction caisson)材料为钢材,密度为7.85,弹性模量为215GPa,泊松比为0.28。桶的尺寸为一般海洋岩土工程中的尺寸,直径为10m,桶长为6m,桶厚与顶盖厚皆为0.1m。
2. 建模
模型网格划分C3D8单元
边界条件:底部固定,桶的外侧施加50kPa的压强
分成10个增量步,每个增量步0.1s,后台采用iSolver求解器计算
