形状记忆合金的动态加热控制方法研究

机械工程材料 2004年第6期28卷 7-9,48页

作者：朱玉田萩原一郎毛利泰裕 horn-sen Tzou 合肥工业大学机械与汽车工程学院安徽合肥230009 东京工业大学大学院机械科学科肯塔基大学美国肯塔基40506

由于环境温度、热对流和热辐射条件以及输入的加热电流强度的不同,致使嵌在复合材料中的形状记忆合金的温度难以确定。为了在最短时间促成形状记忆合金的相变并防止因过热而烧毁复合材料或形状记忆合金驱动元件,提出了一种基于电阻变化... 详细信息

由于环境温度、热对流和热辐射条件以及输入的加热电流强度的不同,致使嵌在复合材料中的形状记忆合金的温度难以确定。为了在最短时间促成形状记忆合金的相变并防止因过热而烧毁复合材料或形状记忆合金驱动元件,提出了一种基于电阻变化率反馈的动态自传感加热方法,它可以实时监测相变的起始点和结束点,有效地防止过热。试验结果与理论分析吻合良好。

关键词：形状记忆合金电阻变化率反馈加热控制

＜正＞Second-order analysis as a new and robust design method has been introduced in many modern codes such as drafted LRFD（2010）,Eurocode-3（2005） and HkSC（2005） and becomes widely used in *** the traditional design method,which is based on the linearized structural response in conjunction with the effective length factor or the k-factor for stability checking,second-order or advanced analysis captures the true behavior in nonlinear range and considers the second-order effects,initial imperfections and material yielding in the process of *** to the superiority in theory,second-order analysis only needs the section design via the section capacity check rather than member design for safety and stability check and therefore avoids uncertainty in determination of effective *** change in design philosophy will likely make the traditional linear design method obsolete in the computer age *** is also noted that in last two decades many strong earthquakes occurred in the world which led to severe damage of numerous buildings and loss of thousands of *** to simplification in the linear theory,the lateral force method and model response spectrum analysis method have many limitations in seismic *** the contrary,the push-over and time history analysis,which are based on the same theoretical background as the second-order analysis,are believed to become more popular under the wide acceptance of performance-based seismic design,especially in meeting multiple performance *** this paper,the basic theoretical framework of second-order analysis for conventional structural design is briefly introduced and this method is extended to performance-based seismic design with the consideration of geometrical change and material ***,the proposed second-order/advanced analysis can be applied to seismic and non-seismic design of building structures.

purpose:The aim of the study was to evaluate the influence of optic disc size on the variables of laser scanning polarimetry(GDx).patients and methods:One hundred and nineteen healthy controls and 161 patients with ocular hypertension(OHT)received detailed ophthalmologic investigation with respect to glaucoma including retinal nerve fiber analysis with GDx(Version 3.0.05× 1;Laser Diagnostic Technologies Europe).Optic disc size was measured with planimetry using 15° optic disc *** respect to frequency of optic disc size in the normal population patients were divided in quartiles of equal sample ***:The ratio between retinal nerve fiber layer thickness in the superior and inferior areas in relation to the nasal and temporal regions decreases significantly with increasing optic disc size and the difference between the highest and lowest retinal nerve fiber layer thickness decreases significantly with increasing optic disc *** results of multivariate neural network analysis increased with larger optic disc size in controls as well as in patients with *** regression analysis showed an increase of 9 units(the Number)per 1 mm2 of optic disc size.A Number above 30,which indicates suspected glaucoma,was detected in more than a third of the normal population investigated if the optic disc area was larger than 3.5 ***,patients with OHT had a higher Number than controls(20.5± 11.5 vs.18.1± 10.4;p >0.05),but the difference between the two groups did not reach a significant ***:Retinal nerve fiber analysis in patients with an optic disc size larger than 3.5mm2 should be interpreted carefully;the Number in particular requires corrections for optic disc size.

当通用汽车在1985年推出土星汽车时，这种新型汽车迅速被消费者接受。但好景不长，土星汽车在1994达到高峰后，便陷入下滑的局面。通用立即对该部门进行了重组，取消了它的部分自主权。然而就在2004年，通用毅然决定再次投入30亿美元，准备为土星重新注入活力。但结果却是：土星仍然没有给通用带来任何切实的利润。
