Szukana fraza: [Abstrakt = "This paper presents a coupled computational model for dynamic analysis of the electromagnetic vibrating table. The model contains description of the magnetic field and the electrical circuit taking account of the linear motion. Studied system consists of an electromagnet fixed on the steel slab and an aluminum plate suspended on springs with permanent magnets mounted underneath. In order to describe the magnetic circuit a two–dimensional finite element method is used. Coupling between the electrical and magnetic circuits is realized by current that flows through the winding of the electromagnet, whereas the coupling between the magnetic circuit and the mechanical model is accomplished by a magnetic force determined from the Maxwell's stress tensor. A linear movement is modeled using distorted elements. The influence of saturation of the magnetic circuit on the calculation results is examined showing small impact on the system performance."]
