The subject comes from actual production, with Jiangxi Copper Group (Dexing) FoundryCompany’s research and development cooperation projects. YAH2460purchased from acompany because of heavy shaker harsh working conditions found in use for some time under thesieve frame beams and side connections, there are several obvious cracks due shaker in the actualwork process failure rate, accident large risks, maintenance human consumption, in order toreduce equipment costs and accidents, and further improve its screening efficiency forheavy-duty vibrating screen for YAH2460parameter optimization design and finite elementanalysis.(1) the whole of the program design, according to the vibrating screen size required to selecta reasonable argument, and the various process parameters shaker, kinetic parameters, kinematicparameters were calculated and used to complete a shaker solidworks3D and2D design. In orderto avoid starting or stopping when the resonance, also designed the swing motor base, avoidingover-shaker resonance region, the pull-off belts and damage the motor.(2) By Matlab to complete shaker parameter optimization, to improve productivity andreduce power consumption to optimize the objective to establish a mathematical model obtainedby optimizing the amplitude becomes6mm., Projectile strength2.996and inclination20.42°.Optimized consumption was reduced by0.0143Kw h/t units of productivity, with the originalunit of production compared to lower power consumption by about36%.(3) Using ANSYS Workbench completed YAH2460heavy shaker screen frame Statics anddynamics analysis through static analysis to identify shaker stress concentration areas for analysis,propose solutions to crack problems in two ways, first kind of innovative welding process;second is to reduce welding, flanged. Meanwhile, the screen frame for modal analysis, extractionof the screen frame shapes top30bands, and then the natural frequencies and vibration sievewere compared, comparative results are in resonance phenomena occur during normal operation.But also on the eccentric shaft modal analysis, modal analysis through eccentric shaft designmeets the requirements, the calculated critical speed eccentric shaft to determine motor selectionis reasonable.(4) This topic is also the realization of the shaker motor speed control, mainly through thecalculation of the appropriate choice of frequency converter is achieved by adjusting the motorspeed, you can get different vibration shaker times, you can choose according to differentworking conditions different vibration times, also can realize the soft start on the motor.
