Currently screening machinery has been introduced dynamic analysis

        Currently screening machine designed to conventional design calculations and analog design method based. But modern design methods, gradually began screening machine

design applications. So it can be used as an iron equipment selection, because the structure of the sand screen design is advanced and reasonable, solid and reliable,

parameter optimization design requirements correctly, so that coal mining machinemachines operate at higher efficiency and longer service life.
   
        Technology developed countries, has been more generally introduced into the dynamic analysis of modern structural design. The process generally, first based on

experience or practical requirements and other conditions for the preliminary design of the original, in this based on the mechanical model of the mechanical model for the

structural strength analysis and dynamic analysis, the results of the analysis and design requirements were compared; if the right design is not satisfied, it is necessary to

modify the preliminary design of the revised structure, further strength analysis and dynamic analysis, redesign, and then modify, re-analysis, until fully meet the design

requirement.

        Computer-aided design (CAD) is produced from the early 1960s and developed. Its appearance is greatly improved traditional design methods, and showed great vitality.

Optimization method with the design, can meet the shaker required in the field case, the optimal configuration of the parameters. In order to meet the needs of engineering

design, CAD design system generally, including graphic design, engineering analysis and design optimization techniques.
