| Abstract: | The method of building the FEM model of the plate-beam combined structure and the method of dealing with the plate-beam non-standard connection are discussed.The FEM simplified model of vibrating screen is built,and the natural characteristic is analyzed.The results show that the time and cost of calculation are reduced,at the same time,the mass distribution and the real stiffness of the vibrating screen are satisfied basically in the simplified model. |
