通过对路面的不平整实地测量资料来获取汽车荷载的参数及计算模型,根据此模型对公路结构中的动力响应情况进行分析,由于公路的结构具有三维分层性状,可以使用Fourier变换技术与求解层状结构的精确刚度矩阵法对公路结构域汽车移动下荷载的动力响应问题进行了研究。
The parameter and calculation model of vehicle load can be obtained by measuring the unevenness of the road surface. According to this model, the dynamic response of highway structure is analyzed. Because of the three-dimensional hierarchical structure of highway structure, Fourier transform technique and solution The accurate stiffness matrix method of layered structure is used to study the dynamic response of highway under the load of moving vehicles.
