| 1 | 车桥耦合系统在随机激励下的动力分析及其应用显示文摘通过建立随机激励下的车桥耦合系统的空间动力模型,研究了提速条件下上承式钢板梁的加固问题。根据实测的轮对加速度,由时间序列自回归模型生成随机激励作为系统的输入,对列车通过桥梁的全过程进行了计算机模拟,得到桥梁的动力响应,并对计算结果进行了统计分析。根据计算结果,设计了上承式钢板梁桥的加固方案,对实际桥梁进行了加固。在桥梁加固前后分别进行了现场测试,结果证明了本文分析方法的正确性和加固方案的合理性。 | 夏禾 张宏杰 曹艳梅 G.De Roeck | 2003 | 工程力学2003,20,3: | 35 |
| 2 | 制动力作用下车辆-车站结构耦合系统分析显示文摘研究制动力作用下车辆-结构耦合系统的分析方法。以刚体动力学方法建立车辆子系统模型,以振型叠加法建立结构子系统模型,以给定的制动加速度时程、简化的Kalker蠕滑理论和轮轨密贴假定分别定义纵向、横向和竖向轮轨间相互作用力,采用时程积分和时间步内的力-运动状态迭代方式求解运动方程。作为算例,研究了深圳地铁4号线、6号线列车制动于深圳北站时车辆-结构动力耦合系统的动力响应,并对车站结构关键部位的振动状态做出了分析和评价。 | 张楠 夏禾 程潜 G.De Roeck | 2011 | 振动与冲击2011,30,2: | 18 |
| 3 | Experimental investigation of railway train-induced vibrations of surrounding ground and a nearby multi-story building显示文摘In this paper, a field experiment was carried out to study train-induced environmental vibrations. During the field experiment, velocity responses were measured at different locations of a six-story masonry structure near the Beijing-Guangzhou Railway and along a small road adjacent to the building. The results show that the velocity response levels of the environmental ground and the building floors increase with train speed, and attenuate with the distance to the railway track. Heavier freight trains induce greater vibrations than lighter passenger trains. In the multi-story building, the lateral velocity levels increase monotonically with floor elevation, while the vertical ones increase with floor elevation in a fluctuating manner. The indoor floor vibrations are much lower than the outdoor ground vibrations. The lateral vibration of the building along the direction of weak structural stiffness is greater than along the direction with stronger stiffness. A larger room produces greater floor vibrations than the staircase at the same elevation, and the vibration at the center of a room is greater than at its corner. The vibrations of the building were compared with the Federal Transportation Railroad Administration (FTA) criteria for acceptable ground-borne vibrations expressed in terms of rms velocity levels in decibels. The results show that the train-induced building vibrations are serious, and some exceed the allowance given in relevant criterion. | Xia He Chen Jianguo Wei Pengbo Xia Chaoyi G. De Roeck G.

| 4 | 基于车激响应和灵敏度分析的桥梁结构损伤识别方法研究显示文摘提出了一种利用桥梁结构在车辆荷载作用下在线响应评估结构性损伤的方法。以单元弯曲刚度的变化量为识别指标,基于车桥动力相互作用理论计算车激桥梁响应以及响应对损伤指数的灵敏度,以结构不同状态下的响应残差为约束条件,利用最小二乘法求解灵敏度方程得到各单元的损伤指数,然后通过有限元更新技术和反复迭代,最终实现对桥梁损伤的定位和定量分析。分析了测量噪声和轨道不平顺对损伤识别结果的影响规律。数值算例表明,所提的损伤识别方法对轨道不平顺和量测噪声不敏感,可以利用加速度、速度或者位移响应有效识别桥梁的绝对损伤或相对损伤。 | 战家旺 夏禾 陈上有 De Roeck G | 2011 | 工程力学2011,28,11: | 10 |
| 5 | 意大利高速铁路Sesia大桥的动力特性及车桥耦合振动分析显示文摘建立了包括钢轨、轨枕、道床、梁体在内的意大利Sesia大桥空间有限元模型,对桥梁的自振特性进行了计算和实测分析。按照轮轨密贴接触假定推导了车-桥系统耦合运动方程组,以德国低干扰谱生成轨道不平顺样本作为激励源,对意大利ETR500Y高速列车通过Sesia大桥引起的桥梁动力响应和桥上车辆的振动响应进行了计算分析,讨论了共振车速的范围并对桥上车辆的运行安全性和平稳性进行了评价。部分计算结果与实测数据进行了对比,吻合较好,从而验证了所建立的模型及分析方法的精度和有效性。结果表明:Sesia大桥结构刚度很大,当列车以288 km/h的速度通过时,挠跨比只有1/17510;当列车以340 km/h的速度通过时,桥梁的竖向位移出现了一个较为明显的峰值,说明这一速度可能引发结构共振;桥上车辆的各项动力指标响应值均很小,能较好地满足高速行车要求。 | 郭薇薇 夏禾 De Roeck Guido | 2013 | 振动与冲击2013,32,15: | 9 |
| 6 | 杆件轴力的一种识别方法显示文摘针对杆系结构中的轴力杆或索缆结构中的短索,提出了一种解析方法识别边界不确定杆件的绝对轴力,重点探讨了杆件抗弯刚度的影响。基于振动测试提取杆件的固有频率、位移模态或应变模态,以此构建特征方程进而识别其绝对轴力。数值算例分析表明,本方法在采用不同阶次的模态参数以及不同的杆件边界条件下都可取得相对误差3%以下的高精度识别结果,且在不测量杆件两端节点的有效长度、仅已知传感器之间的相对位置时即可实施。试验证实,基于加速度测量得到的前5阶模态参数都可基本准确地识别不同加载工况下杆件的绝对轴力,除小荷载外的多数工况都取得了相对误差10%以下的良好识别效果。 | 李素贞 G.
