[Abstract]:Vibration machine is a kind of mechanical equipment which uses vibration principle to complete all kinds of technological processes. At present, this kind of machinery has been widely used in industrial and agricultural production and national defense construction and other departments. With the further development of economic construction and scientific research in China, vibration machinery for new uses will emerge and play an increasingly important role. With the rapid development of modern design theory and computer technology, in order to ensure the reliability and effective operation of this kind of machinery, it is very important to apply new scientific and technological methods to the comprehensive and systematic study of vibration machinery. Based on virtual prototyping technology, the dynamics of inertial vibration machinery is studied as follows: the dynamic analysis of various inertial vibration machinery is carried out, and the solid model is established by using PRO/E software. It is introduced into ADAMS software, and the motion theory of vibration machinery is verified by simulation research, which provides a theoretical basis for the research and development of new type vibration machinery. A new type of complex frequency vibration is proposed. Based on the principle of complex frequency vibration, two different virtual prototype models of complex frequency vibration mechanism are established, and the theory of complex frequency vibration is verified by simulation. The mathematical model of electromechanical coupling of two motor excitation system is established, and the Matlab/Simulink simulation model of three-phase asynchronous vibration motor and the virtual prototype model of two-axis self-synchronous linear vibrating screen are established. The simulation analysis of the motor and vibration system is carried out. The complex self-synchronization phenomenon is explained in detail. The theory of material motion is analyzed, and the influence of vibration mechanism on material motion is analyzed by PRO/E and ADAMS software, which is of great significance to the selection of vibration parameters of vibration machinery.
