[Abstract]:Heavy plate feeder is the key equipment for the automation of material transfer and transportation in metal and non-metal mines, and its performance directly affects the production efficiency and safety of mining and transportation. The motor power, dynamic performance and structural strength of key parts are analyzed and calculated under different working conditions. Firstly, according to the principle of chain transmission, the method of calculating the total resistance of driving sprocket is given. On this basis, the required power of driving sprocket under full load and no-load conditions is obtained. Secondly, the virtual prototype model of plate feeder is established by using the crawler module of multi-body dynamics software RecurDyn. The motor power of heavy-duty plate feeder in the three stages of no-load and full-load start-up, steady operation and braking is analyzed, and compared with the theoretical calculation results, the rationality of the theoretical calculation is further verified. The rigid-flexible coupling model of the driving shaft is established. The dynamic strength of the driving shaft under different working conditions is analyzed with the driving power as the loading condition, and the real-time variation of the node stress at the dangerous position is extracted. On this basis, the reliability of the drive shaft is evaluated. Finally, the finite element model of the key parts, such as the bracket, the drive shaft and the chain plate, is established, and the strength and stiffness of the key parts under dangerous working conditions are analyzed. Modal analysis was carried out to obtain the weak position of the support by vibration mode, which provided guidance for improving the design. In this paper, the calculation method of motor driving power of heavy plate feeder, the dynamic simulation of virtual prototype and the establishment and analysis method of rigid-flexible coupling model of key parts are presented, which provides a reference for the design of heavy plate feeder.
