This paper presents a statistically refined Bouc-wen model of tri-axial interactions for the identification of structural systems under tri-directional seismic excitations. Through limited vibration measurements in the National Center for Research on Earthquake Engineering in Taiwan conducting model-based experiments, the 3-D Bouc-wen model has been statistically and repetitively refined using the 95% confidence interval of the estimated structural parameters to determine their statistical significance in a multiple regression setting. When the parameters＇ confidence interval covers the ＂null＂ value, it is statistically sustainable to truncate such parameters. The remaining parameters will repetitively undergo such parameter sifting process for model refinement until all the parameters＇ statistical significance cannot be further improved. The effectiveness of the refined model has been shown considering the effects of sampling errors, of coupled restoring forces in tri-directions, and of the under-over-parameterization of structural systems. Sifted and estimated parameters such as the stiffness, and its corresponding natural frequency, resulting from the identification methodology developed in this study are carefully observed for system vibration control.

Frontiers of Philosophy in China 2012年第4期7卷 598-599页

作者： Ralph Weber wen Haiming

Roger T. Ames, who teaches at the University of Hawai＇i at Manoa, is beyond any doubt one of the most prominent and original voices in current discourse on Chinese philosophy. For decades he has been extremely active in advocating an understanding of ancient Chinese texts that is explicitly philosophical, that is, it speaks directly to the philosophically minded （and not primarily to the philologically oriented sinologist）. Despite this clearly confined group of addressees, he speaks decidedly not in the terminology most familiar to practitioners of dominant or mainstream Westem philosophy. Although he frequently draws contrasts and analogies with more familiar figures and more general features of Western philosophy, his favorite approach makes it a point--in fact, the central point--to give Chinese philosophy a voice of its own and thus to read its texts ＂on their own terms＂（to be understood in its double meaning as conditions and vocabulary）. But, as Ames is very much aware, translating these texts on these terms still requires a vocabulary that is not their ＂own＂-and he has thus chosen dominantly the vocabulary of early American pragmatism as the most useful in articulating what he perceives are the sensibilities of Chinese philosophy. With his many interpretative studies and philosophical translations （often co-authored with David L. Hall and Henry Rosemont Jr.）, he has pushed the frontiers of Chinese philosophy as much as of philosophy in China in various ways and into various directions--something that has found an impressive echo both in terms of followers （many relate a story that they initially became interested in Chinese philosophy by having read, say, Hall and -Ames＇s Thinking Through Confucius） and in terms of critics, who have taken issue with particular translations, the overall approach, or with both.

工程中常用Bouc-wen模型来描述具有滞回特性的振动系统,此类系统是一种多值性的非解析系统,其动力学理论分析比较困难。由于Bouc-wen滞回模型的微分形式,一般采用数值方法进行积分求解,但对于多自由度系统来说求解速度非常慢,且难以求得不稳定解。故提出将滞回力引入为一个增加的自由度,重新建立振动系统的微分方程,将增量谐波平衡(IHB)法推广至求解该类含Bouc-wen模型的多自由度滞回非线性系统,并引入弧长法解决由迟滞非线性引起的跳跃和多映射现象。利用该法分析了一些滞回系统的响应特性,通过与数值方法进行精度和效率对比,体现了该方法的优越性。

针对平头弹丸穿透固支圆形金属薄靶问题,对wen-Jones模型进行了推广应用。根据前人的研究成果,提出了等效应变失效准则,以预测金属薄靶的穿透。与实验数据的对比表明,新模型的预测结果与有关低碳钢和铝合金的实验结果相吻合。尽管新模型与wenJones模型采用的破坏准则不同,但是两者的预测结果相近。分析发现,当靶板材料的延性足够大时,wen-Jones模型可看作是新模型的一种特殊情况。

在经典Bouc-wen模型的基础上,介绍了一种能更好地模拟防屈曲支撑材料塑性硬化及力学参数非对称性特点的改进Bouc-wen模型。采用单参量变化法对改进Bouc-wen模型的各项参数进行了敏感性分析,基于敏感性分析结果及目标函数最优解求解特点,给出了基于改进梯度下降法的参数拟合方法,并在参数拟合精度及拟合效率方面与遗传算法、粒子群优化算法进行了对比分析。通过防屈曲支撑的静力往复试验结果验证给出的参数拟合模型及参数拟合方法的有效性。结果表明,改进的Bouc-wen模型能更好地模拟防屈曲支撑的滞回特性。相较于遗传算法、粒子群优化算法等参数拟合方法,改进的梯度下降法具有更高的参数拟合精度及拟合效率,并且能有效拟合改进Bouc-wen模型的各项参数,防屈曲支撑拟合滞回曲线与试验滞回曲线有较高的吻合度。
