摘要
研究稳定性悬索桥在运输载荷通过时的动态响应问题,导出了动力加载模式,用有理近似法求解系统非线性有限元动力方程.分析了动力响应特征.
The dynamic response problem of stable type suspension bridge is researched under mobile load. The load model of move vehicle for calculation is driven. The nonlinear finite element equations of the system are solved with Rational Approximate Method. The bridge's characteristic of dynamic response is shown and analyzed.
