摘要
应用任意拉格朗日欧拉方法对具有典型流线型桥断面进行气弹性分析,得到升力系数以及力矩系数历程,然后用最小二乘法得到气动导数,计算气动导数与实验有较好的一致性,证明了该方法可以进行桥梁振动气动设计,为模拟流固耦合问题提供一个重要方法。
The atmospheric elasticity of typical clipper-built bridge section models was analyzed by arbitrary Lagrange Euler method.Via the least square method,the pneumatic derivatives obtained from lift coefficient and moment coefficient temporal courses are in agreement with experimental results.These conclusions show that the arbitrary Lagrange Euler method can be used to study the aerodynamic vibrations of bridges,and to solve structure-fluid coupling problems.
