Dynamic analysis of the plate on multi-elastic-layer foundation under moving load

Tóm tắt

The dynamic respones of the plate under moving load is an open problem, it has been researched, developed in many majors of solid mechanics, particularly in transport construction. This article presents a methodology of finite element analysis and a solution of the partial differential equation for the structure of the Kirchhoff plate on the multi-elastic-layer foundation bearing moving load. In which, the multi-elastic-layer foundation is described as the homogeneous Winkler foundation. The moving load with mass oscillates together with the plate. The surveys have been studied in order to show the effects of parameters of foundation and load to the oscillation of the plate.
