在消能减震措施中,为达到满意的减震效果,需在建筑结构的多个楼层布置耗能装置,占用了较多的建筑空间,为此提出仅需在底部楼层布置耗能装置的负刚度阻尼消能减震技术方案。为实现该方案,研发了一种力学性能稳定、构造简单,行程大,具有负刚度特征的半周摩擦阻尼装置。通过性能试验验证了该装置能够实现预期的滞回模型,进行了单自由度体系和框架结构的减震模拟分析,结果表明,采用半周摩擦阻尼装置进行减震可以增大结构阻尼、延长结构周期、对结构地震响应起到理想的控制效果。

为有效改进航空搭接接头制造工艺,建立次弯曲效应下的中心线模型,并采用ABAQUS/Explicit与ABAQUS/Standard相结合的仿真方法,研究了飞机蒙皮上的多排铆钉搭接接头的铆接工艺及其影响下的结构受载内应力与变形。结果表明:采用适当的铆接参数可以极大地改善连接孔应力集中及结构疲劳特性。在疲劳载荷作用下,结构失效更容易发生在外排铆钉连接板的贴合面与孔表相交的位置,特别是靠镦粗钉头的连接板内。次弯曲会对结构受载后内部应力分布产生显著影响,但在孔的附近钉头覆盖下的区域应力特征受弯曲效应影响较小,铆接残余应力的影响仍然占主导地位。可见在工程应用中,更应该从连接孔周围挤压应力改善的角度寻求结构疲劳寿命增益。

Image interpolation of cross-sections is one of the key steps of medical visualization, and the cubic convolution interpolation is usually employed due to its good tradeoff between computational cost and accuracy, however, sometimes its accuracy can still not meet the requirement. Aimed at the problem, in this paper, the interpolation principle based cubic convolution is firstly analyzed systematically, and then essential relationship among the different cubic convolution interpolation methods is clarified. Lastly, a novel cross-section interpolation method for medical images that is based on the optimal parameter of sharp control is presented. The method takes full advantage of the local characteristic of medical images, and the optimized sharp control parameter is obtained by the iterative computation, and then the cross-section interpolation is performed by the cubic convolution with the optimized parameter in one *** experimental results show that the method presented in the paper not only can improve the interpolation accuracy effectively, but also is robust.
