[Abstract]:With the rapid development of national economy, the environmental requirements are becoming higher and higher, and more attention has been paid to the clean and environmentally friendly use of coal. As an important equipment for coal treatment, vibrating screening equipment is widely used in coal preparation plants at various levels. It plays an important role in the deep processing, screening and cleaning of coal. The high frequency vibrating screen is the commonly used vibrating screen in coal preparation plant. This paper takes GPS2445 high frequency vibrating screen as the research object, the parameters of the vibrating screen are selected and calculated, and the kinematics and dynamics parameters of the vibrating screen are obtained. The structure of the vibrating screen is designed by using Creo Parametric software, and the three-dimensional model of the vibrating screen is obtained. In the aspect of static analysis, the mechanical analysis of vibrating screen is carried out, the mechanical model is established, and the load type and load size of vibrating screen are analyzed and calculated. According to the calculated load size, the stress and deformation cloud diagrams of the supporting beam and spring support are obtained by using ANSYS Workbench software to analyze the key components of the vibration screen. The results of statics analysis show that the supporting beam and spring bearing are reasonable in design and reliable in strength. In the aspect of dynamic analysis, modal analysis and harmonic response analysis of the screen box of GPS2445 vibrating screen are carried out. Through modal analysis, the first 10 vibration modes of the vibrating screen box are obtained, and the stress, deformation and acceleration responses of the screen box at 0-150 Hz frequency are obtained by harmonic response analysis. At the same time, the stress and deformation of the screen box at 60 Hz resonance frequency and 15. 8 Hz power frequency are analyzed. The results show that the vibrating screen has good stability and safety under the power frequency condition.
