Describe the rational screening machine structural stress distribution

        In China, the computer-aided design gradually screening machine design applications, nearly 20 years. In addition to using graphics package graphics rendering machine,

but in the current vibrating screen design, the following analytical methods have been and are being widely used. They are the finite element method, modal analysis, mechanical

design and structural optimization method to modify the dynamic characteristics of technology. These are the important part of the computer-aided design.
   
        Optimization method with the design, can meet the shaker required in the field case, the optimal configuration of the parameters. Finite element analysis, can provide

overall screen box structure rational distribution of stress and strain state. Many examples illustrate, in combination plate girder structure based shaker, finite element

analysis can be obtained at a reasonable screen box structure strength, have a good effect. Modal analysis is used instead of the real structure model for dynamic analysis, in

general the results more accurate.

        Modal analysis results can be directly used to evaluate the linear vibrating screen box structure design is reasonable, and for structural dynamic response analysis and fatigue design

basis. Cement kiln manufacturers modify the dynamic characteristics of the structure that is in modal analysis techniques developed on the basis that it can be targeted for

structural modifications, and then modify the structure of the process to avoid blindness. Highly versatile shaker graphic design, there is not as described.
