海上完井滑套开关工具弹性爪机构性能研究

Shiyou jixie, 2014
弹性爪机构是海上完井滑套开关工具中最重要的部件，其力学性能稳定性对于作业成败至关重要。基于受力分析和有限元模拟，建立开关工具弹性爪力学理论模型和三维有限元分析模型，研究弹性爪结构应力分布与作业性能。基于受力理论分析可知，弹性爪机构最大轴向拉力为4 116 N，最大应力为675 MPa；基于有限元模拟计算，弹性爪机构最大轴向拉力为3 924 N，最大应力747 MPa，弹性爪结构强度满足要求。功能试验结果表明，理论计算方法存在一定的误差，有限元模拟结果相对比较精确和可靠 ...

Jianzhu Gangjiegou Jinzhan
为研究T形钢管混凝土柱-H形钢梁侧接板式节点的受力机理，对该节点进行了有限元模拟和理论分析研究。首先建立Abaqus有限元数值模型，通过试验结果验证了数值模型的合理性；根据节点构造特点，推导了该节点的受弯承载力和受剪承载力计算公式，并采用数值模型算例进行验证；基于计算公式分析不同变量对节点受弯承载力和受剪承载力的影响。研究结果表明：给出的有限元模型能够有效模拟侧接板式节点的工作状态和极限承载力；侧接板式节点的受弯破坏有4种破坏形态，通过合理构造可以确保首先出现钢梁翼缘受拉屈服破坏，实现节点的延性破坏 ...
