摘要/Abstract

摘要：

为研究悬锤系统在桥梁动力测试中的应用，以标准跨径简支梁/板桥为对象，采用理论推导、数值模拟与试验验证相结合的方法开展研究。首先，根据达朗贝尔原理推导了车-桥-悬锤系统耦合振动理论方程；然后，基于ANSYS软件编制分析程序进行数值计算，研究悬挂长度、铁丝直径、弹性模量以及悬锤质量对悬锤法测试冲击系数结果的影响，并与支架法测试结果对比，结合响应面分析，针对不同桥型提出了悬锤系统参数选型建议；最后，选取一座30 m简支箱梁桥进行动载试验，分别采用支架法与悬锤法测试挠度冲击系数，验证本文参数选型。结果表明：铁丝直径和悬锤质量交互作用显著；为满足悬锤法与支架法测量冲击系数差值小于5%的要求，铁丝直径以及悬锤质量的最佳取值应随悬挂长度增加而增大。

Abstract:

To explore the application of hammer system in bridge dynamic test， simply supported bridge with standard span were selected. Research on dynamic load allowance （DLA） test of simply supported bridge were carried out， adopting theoretical derivation， numerical simulation and experimental verification. Firstly， the vehicle-bridge-suspension system coupled vibration theoretical equation was derived according to d'Alembert principle. Then， the analysis program was compiled based on ANSYS to obtain the DLAs of suspension hammer method. The influence of suspension length， wire diameter， elastic modulus and suspension hammer mass on the accuracy of DLA were discussed， comparing with the results of scaffolding method. Furthermore， combining with response surface methodology， the suggested value of suspension hammer system parameters about different bridges types were proposed. Finally， a 30 m simply supported box girder bridge was tested under dynamic load. Dynamic deflection of the bridge was tested by scaffolding and suspension hammer method to verify the suggested value. Results demonstrated that there is a significant interaction between wire diameter and suspension hammer mass. To satisfy the difference of less than 5% between deflection DLA measured by suspension hammer and scaffolding method， the optimal values of wire diameter and suspension hammer mass should increase with wire length.
