提出一种双曲型钢管叠层黏弹性阻尼器，介绍构造、原理与特点。采用ABAQUS软件，建立钢管阻尼器、双曲型钢管阻尼器、钢管叠层黏弹性阻尼器和双曲型钢管叠层黏弹性阻尼器4种阻尼器有限元模型，从应力分布、力学性能进行模拟分析，结果表明：在钢管阻尼器内设置叠层黏弹性体可有效延缓钢管局部屈曲，充分发挥钢管耗能能力；双曲型钢管形式改善钢管阻尼器应力分布，使变形和耗能集中于阻尼器中部，避免阻尼器端部和连接处破坏；...
通过数值模拟和理论分析，研究了盾构隧道开挖面挤出破坏机理。首先，利用有限元软件进行了数值模拟，揭示了隧道开挖面挤出破坏的局部失稳模式，得到了盾构隧道开挖面挤出破坏的局部失稳比和极限支护压力。此外，还进行了摩擦角和相对埋深对局部失稳比率和极限支护压力的参数敏感性分析。其次，基于极限分析方法，提出了一种考虑局部失稳模式的隧道开挖面挤出破坏新机制。新的被动破坏机理由五个圆锥台和作用在圆锥台上的分布力组成...

针对平衡炮试验中常用的前后定心式弹托设计，在文献［3］Forrestal侵彻模型基础上，建立带前后定心式弹托的刚性弹体侵彻模型，分析弹托相对附加质量、弹托组件与弹体连接强度、侵彻着速等因素对弹体侵彻终点效应的影响规律。分析结果表明：弹托附加质量越大，对侵彻深度增益越明显；随着侵彻初速的提高，弹托附加质量对侵彻深度增加量的影响逐渐增大，弹托的连接强度对侵彻深度的影响越来越小。
