A modified cuckoo search(CS) algorithm is proposed to solve economic dispatch(ED) problems that have nonconvex, non-continuous or non-linear solution spaces considering valve-point effects, prohibited operating zones, transmission losses and ramp rate limits. Comparing with the traditional cuckoo search algorithm, we propose a self-adaptive step size and some neighbor-study strategies to enhance search ***, an improved lambda iteration strategy is used to generate new solutions. To show the superiority of the proposed algorithm over several classic algorithms, four systems with different benchmarks are tested. The results show its efficiency to solve economic dispatch problems, especially for large-scale systems.

On the basis of analyzing the basic information of single type of product and constraint relations between parts and components, the constraint relations are showed by Petri net model, in which we introduce the factors of time and resources into places and transitions. This paper proposes lot sizing selective disassembly optimization problem based on timed Petri net with consideration of multi-resources constraints, establishes a mathematical model of this problem aims at minimization of disassembly time, solves the model with CPLEX software, and verifies the effectiveness of this model in solving this type of disassembly optimization problem through the disassembly example of silicon oil fan and several randomly generated problem instances.

通过双面剪切试验,研究了-20~60℃的温度循环作用后CFRP板-混凝土界面极限承载力的变化规律。对比分析了未经季节温度循环和经历50、100、150次季节温度循环后材料的宏观力学性能、界面破坏特征和界面极限承载力等变化规律。结果表明:随着季节温度循环次数的增加,环氧树脂胶由于后固化作用,其抗拉强度、抗剪强度及弹性模量升高,伸长率有所降低;季节温度循环次数的增加对混凝土和CFRP板的力学性能影响较小;C30、C50混凝土强度界面破坏形式不同;随着季节温度循环次数的增加,界面极限承载力增加。同时,在Naubauer&Rostasy模型、Chen&Teng模型和陆新征模型的基础上,提出了季节温度循环后界面极限承载力修正模型,结果发现模型计算值与试验值吻合较好。

采用CFRP加固带裂缝混凝土梁,能明显提高构件的承载力和刚度,减小结构变形并延缓裂缝的扩展。由于混凝土材料本身和CFRP-混凝土界面的率敏感性,在动态加载速率下CFRP加固梁的断裂性能与准静态荷载下有着明显不同。为研究CFRP加固混凝土梁的动态力学性能,通过不同加载速率下三点弯曲梁断裂试验,对比分析了0.000 5、0.1、1、10 mm/s加载速率下CFRP加固预裂混凝土梁的断裂性能。结果表明:CFRP在混凝土梁裂缝扩展过程中承担着很强的阻裂作用和增强效果,与未加固混凝土梁相比,CFRP加固混凝土梁的极限荷载得到显著提高;随加载速率提高,混凝土梁固有的阻裂性能和断裂过程区骨料黏聚力的阻裂作用提高,混凝土梁断裂面骨料被拉断的数量增多,裂缝扩展路径更趋向平直;最后计算得到不同加载速率下CFRP加固混凝土梁裂缝扩展阻力曲线,分析了不同加载速率下CFRP加固混凝土梁裂缝扩展阻力曲线的变化规律。
