| 1 | The stress relaxation of cement clinkers under high temperature显示文摘压碎的精力消费被水泥材料的机械性质直接影响。这研究在高温度下面为水泥 clinkers 的压力松驰的机制提供一个理论证明。在各种各样的高温度下面的压缩压力松驰用一个特殊发达的负担房间被讨论,它能在一个压热器内在高温度下面测量应力和排水量。房间证明压力松驰戏剧性地增加并且留下的压力很快随温度的增加减少。机械实验在冷却过程期间在各种各样的温度下面被进行与温度在水泥 clinker 的磨擦抵抗学习变化。水泥 clinkers 的负担排水量曲线,压缩力量,和有弹性的模量上的高温度的效果系统地被学习。结果证明 clinker 的变硬的现象在温度与减少变得明显并且山峰以后的行为从粘性表明转变的特征到易碎物。有弹性的模量和水泥 clinkers 的压缩力量在温度与减少增加。当温度比 1000 低时,有弹性的模量极大地增加吗?? | Xiufang WANG Yiwang BAO Xiaogen LIU Yan QIU | 2015 | Frontiers of Mechanical Engineering2015，10，4： | 1 |

| 3 | Study on dynamic response of high speed train window glass under tunnel aerodynamic effects显示文摘Purpose-This paper aims to analyze the bearing characteristics of the high speed train window glass under aerodynamic load effects.Design/methodology/approach-In order to obtain the dynamic strain response of passenger compartment window glass during high-speed train crossing the tunnel,taking the passenger compartment window glass of the CRH3 high speed train onWuhan-Guangzhou High Speed Railway as the research object,this study tests the strain dynamic response and maximum principal stress of the high speed train passing through the tunnel entrance and exit,the tunnel and tunnel groups as well as trains meeting in the tunnel at an average speed of 300 km$h-1.Findings-The results show that while crossing the tunnel,the passenger compartment window glass of high speed train is subjected to the alternating action of positive and negative air pressures,which shows the typical mechanic characteristics of the alternating fatigue stress of positive-negative transient strain.The maximum principal stress of passenger compartment window glass for high speed train caused by tunnel aerodynamic effects does not exceed 5 MPa,and the maximum value occurs at the corresponding time of crossing the tunnel groups.The high speed train window glass bears medium and low strain rates under the action of tunnel aerodynamic effects,while the maximum strain rate occurs at the meeting moment when the window glass meets the train head approaching from the opposite side in the tunnel.The shear modulus of laminated glass PVB film that makes up high speed train window glass is sensitive to the temperature and action time.The dynamically equivalent thickness and stiffness of the laminated glass and the dynamic bearing capacity of the window glass decrease with the increase of the action time under tunnel aerodynamic pressure.Thus,the influence of the loading action time and fatigue under tunnel aerodynamic effects on the glass strength should be considered in the design for the bearing performance of high speed train window glass.Originality/value-The research results provide data support for the analysis of mechanical characteristics,damage mechanism,strength design and structural optimization of high speed train glass. | Xiaogen Liu Shuang Qi Detian Wan Dezhi Zheng | 2023 | Railway Sciences2023，2，2： | 0 |
