A example to assess fatigue damage was presented according to the bridge design code of bs5400 so as to show the steps of application and analysis of long - span bridge fatigue damage assessment with fatigue life gage 最后给出利用英国桥梁规范bs5400对大型钢桥进行损伤评估的具体算例,以说明疲劳寿命计结合应变倍增器在大型钢桥疲劳监测中损伤评估的步骤。
Information system is the key of victory under such condition . battlefield information control system is the main technological support of integrated electronic information system . furthermore , it is also a part of weaponry and the intensifier of battle effectiveness 在这种战争中,信息化是制胜的关键,而战场信息处理系统是综合电子信息系统的关键技术支撑,它不仅是武器,也是战斗力的倍增器。
Based on the speciality of load spectrum of bridge , a new method to infer load spectrum of bridge with two fatigue life gage installed on the same strain multiplier was proposed , substantive progress in the fatigue damage calculation applied to the bridge with fatigue life gage 针对桥梁荷载谱特性,提出基于同一倍增器上双疲劳寿命计的桥梁荷载谱推测方法,为基于疲劳寿命计的桥梁疲劳损伤计算,迈出了关键一步。
Abstract : by taking the thinking method of lanchester combat theory , the thesis analyses the combat effect of accurate - attacking weapons under the support of satellite system and also gives us a better explanation of satellite system ' s force - multiplying function 文摘:本文采用兰彻斯特战斗理论的思想方法,对在卫星系统支援下精确制导武器的战斗效能的评价,建立数学模型,进行了定量分析,较好地说明了卫星系统力量倍增器的作用。
Fatigue test indicates that strain multiplier have not been damaged for fatigue in the service life of fatigue life gage , fatigue response of fatigue life gage can be derived from the strain amplitude equal to specimen strain multiplied by amplification coefficient of strain multiplier 疲劳实验研究表明,在疲劳寿命计工作寿命内,应变倍增器无疲劳破坏情况,疲劳寿命计疲劳响应可由静载标定放大倍数乘试件表面应变后所对应的等幅应变值得到。
