摘要:
针对公路桥梁车桥耦合振动响应分析的复杂性,结合分离迭代法原理与车辆动力学理论,提出了基于ANSYS的车桥耦合振动响应数值分析方法.将车辆模型与桥梁模型分别独立建于ANSYS软件环境中,利用约束方程实现任意时刻车轮与桥面接触点的位移协调关系(力的平衡关系自动满足),基于ANSYS瞬态动力学求解功能,采用APDL编程实现车辆(车流)过桥的耦合动力时程响应分析,并与相关文献算例结果进行了定量比较.研究结果表明:该方法精度较高,与文献结果对比,光滑路面下响应相对误差均在5％以内,考虑桥面平整度时响应趋势基本一致;该方法在任意载荷步处不需要迭代计算,避免了复杂程序设计,极大地提高了分析效率.
Abstract:
Aiming at the complexity of the analysis of vehicle-bridge coupled vibration response of highway bridges, combined with the principle of separation iteration method and vehicle dynamics theory, a numerical analysis method of vehicle-bridge coupled vibration response based on ANSYS is proposed. The vehicle model and bridge model are independently built in ANSYS software In the environment, use the constraint equation to realize the displacement coordination relationship between the wheel and the bridge deck contact point at any time (the force balance relationship is automatically satisfied), based on the ANSYS transient dynamics solution function, use APDL programming to realize the coupled dynamics of vehicles (traffic flow) passing the bridge The time-history response analysis was carried out, and a quantitative comparison was made with the results of relevant literature examples. The research results show that the accuracy of this method is relatively high. The response trend is basically the same; this method does not need iterative calculation at any load step, which avoids complex program design and greatly improves the analysis efficiency.
