提出一种完全基于激励和结构响应实测数据的结构动力系统非线性恢复力识别方法,并通过在一个4层钢结构模型中引入具有非线性特性的磁流变阻尼器(MR)模拟非线性恢复力,基于此模型结构在不同的激励方式下的动力响应测量数据,验证了该方法的有效性。对于结构的各自由度均受到激励的情况,运用最小二乘拟合算法识别出等效线性系统的物理参数(质量、刚度和阻尼矩阵),进而得到模型结构振动过程中MR阻尼力随时间变化情况并与实验实测结果进行了比较。针对结构仅在有限自由度上受到激励的情况,对以上方法进行了改进,提出了一种非线性系统恢复力的非参数化识别方法,利用结构中弹性恢复力的对称关系,分步确定了结构各层间恢复力模型,从而得到MR恢复力的大小并与实测结果进行了比较。结果表明,基于时域实测信号的非线性系统恢复力识别法在完整激励和非完整激励下均能有效地识别结构的非线性恢复力特性。文章所述方法可以运用于工程结构在动力荷载作用下的损伤发生发展过程的监测与识别。

This study proposes an eco-innovative design process taking into consideration quality and environmental aspects in prioritizing and solving technical engineering problems. This approach provides a synergy between the Life Cycle Assessment (LCA), the non-quality matrix, the Theory of Inventive Problem Solving (TRIZ), morphological analysis and the Analytical Hierarchy Process (AHP). In the sequence of these tools, LCA assesses the environmental impacts generated by the system. Then, for a better consideration of environmental aspects, a new tool is developed, the non-quality matrix, which defines the problem to be solved first from an environmental point of view. The TRIZ method allows the generation of new concepts and contradiction resolution. Then, the morphological analysis offers the possibility of extending the search space of solutions in a design problem in a systematic way. Finally, the AHP identifies the promising solution(s) by providing a clear logic for the choice made. Their usefulness has been demonstrated through their application to a case study involving a centrifugal spreader with spinning discs.

本文提出了新的两(多) 参数规划(mp-P) 启发算法以求解混合整数非线性规划(MINLP) 问题,并着重说明了算法在过程综合问题中的应用。对于因对数项导致的非线性,开发了针对确定性问题的参数算法(p-MINLP)。关键之处是通过将二进制变量和(或) 不确定参数作为符号参数重新生成和求解一阶Karush Kuhn Tucker(KKT) 系统的解析表达式。为此,采用了符号处理和求解技术。为了证明所提出的算法的适用性和有效性,对两个过程综合案例研究进行了验证,相应的结果经最新的数值MINLP 求解器验证是有效的。对于p-MINLP,给出了不确定参数的显函数表示的最优解。
