摘要
车桥耦合振动问题是铁路和公路桥梁中十分重要的研究课题， 而目前所采用的数值算法所需的时间比较长， 为了减少计算机时， 本文在对高速铁路曲线梁车桥耦合振动研究中， 建立了一种基于激励非线性振动的数值计算方法， 并完成了计算程序 Ｂ Ｓ Ｎ Ｄ Ｓ 的编制， 取得了较好的计算结果． 并将其与其他模型进行比较， 在保证精度的前提下，
The interaction vibration between bridge and vehicle is an important problem in bridges of highway and railway.The numerical methods now usually used need much more time to complete the analysis.With the aim of increasing the computation efficiency,a numerical method which is based on the nonlinear vibration theory is proposed to study the dynamics between vehicle and curved bridge in high speed railway.The program BSNDS is composed to evaluate the method.The simulation proves that the method can decrease the computation time greatly then other models without losing accuracy.
