约束层 meaning in English
restraint layer
Examples
- Experimental research on structure vibration control with active constrained layer damping
主动约束层阻尼结构振动控制试验研究 - Vibration analysis and fem model of hollow circular beam with constrained damping layer
圆形空心截面约束层阻尼梁整体单元建模与振动分析 - Hamilton ' s principle are used to obtain equations of motion , which are discretized using finite element method . the frequency dependent damping of viscoelastic layer is modeled using the golla - hughes - mctavish ( ghm ) method and the system is analyzed in the time domain . ghm increases the size of the original system by adding fictitious dissipation coordinates that account for the frequency dependent damping
本文采用ghm模型描述粘弹性阻尼材料的本构关系,根据哈密顿原理分别对附加主动约束阻尼层结构( acld )和主被动阻尼分离结构( acupcld和acopcld ,其中acupcld结构是将压电作动层贴于粘弹阻尼层的下面, acopcld结构是将被动约束层和压电作动层分别贴于梁的上下表面)的梁结构建立了有限元模型,进而得到系统控制状态方程。 - In addition , active constrained layer damping ( acld ) has attracted scholar ' s interests because it has the advantages of passive control and active control . the mechanism of vibration control of acld and the models of how to deal with the viscid - electric material are introduced . the finite element model of acld with ghm model is established in this paper
此外,主动层阻尼结构( acld )由于兼有被动控制和主动控制两者之优点也引起了国内外学者的兴趣,本文给出了主动层阻尼结构(约束层采用压电材料)抑振的工作机理,介绍了处理粘弹性层( vem )的几种模型,并采用ghm模型建立了主动层阻尼结构的有限元模型。 - Secondly , it begins to explore the vital effect of the early - warning system in survival development for it industry in fujian , besides the characteristics , precondition , building process , structure and function . thirdly , it establishes an index system , which includes a constraint layer of three constraint factors , such as industrial science and technology , industrial economics and industrial circumstance , and 19 indexes . in order to ascertain the dividing lines of alarming situation , it introduces the concept of subordinate degree
论文首先提出福建省电子信息产业可持续发展理论,在此基础上,探索预警系统在可持续发展中的重要作用,分析电子信息产业可持续发展预警系统的特征、建立的前提条件、构建过程及其结构和功能;然后构建一套由产业科技、产业经济和产业环境三个约束因子构成的约束层,及由19个指标构成的福建省电子信息产业可持续发展预警系统指标体系,并引入模糊数学的隶属度概念,将预警界限的确定转化为相应隶属度的确定,预警结果的输出采用红、黄、绿三色信号灯显示系统法;最后用1995 - 2001年福建电子信息产业的相关统计数据对所建立的福建省电子信息产业可持续发展预警系统进行实例验证。
