考虑地基的非线性因素的影响,利用板边剪力等效传力杆作用,建立了非线性弹性地基上具传力杆的刚性路面板的运动控制方程;构造了满足全部边界条件的挠度试函数,应用Galerkin法和描述函数法对非线性方程进行求解,分析了传力杆参数、地基和路面板结构参数变化对非线性弹性地基上具传力杆的刚性路面板的非线性自由振动的影响。
Considering the influence of the nonlinear factors of the foundation, the governing equation of the rigid pavement plate with dowel bar on the nonlinear elastic foundation is established by using the equivalent shear force of the plate-edge shear force. The deflection test which satisfies all the boundary conditions is constructed. Function, the nonlinear equations are solved by Galerkin method and descriptive function method. The nonlinear free vibration of the rigid pavement plate with dowel bar on the nonlinear elastic foundation is analyzed based on the parameters of the dowel bar, the change of structural parameters of the foundation and pavement. influences.
