[Abstract]:As the main equipment for material crushing, cone crusher is widely used in metallurgy, mining, building materials, electric power, chemical industry and so on. Virtual prototyping technology can generate the virtual model of the device on the computer, and carry on the virtual test to its each performance. The application of virtual prototyping technology to the design of conical crusher can make the production and design department completely separate from the physical prototype and shorten the design cycle and reduce the design cost. Improving the competitiveness of the product market is of great significance. By studying the kinematics and dynamics of the cone crusher, the information of rotation speed of the moving cone and the motion characteristic of the point on the moving cone under different working conditions are obtained in this paper. The differential element method is used to solve the inertial force and inertia moment in the process of rotating pendulum with moving cone and eccentric sleeve. In this paper, the influence of the important balance on the movement of eccentric parts is discussed, and the influence of different moving states of eccentric components on the size of discharge port is analyzed. The conclusion can be used to guide the design of balance weight. The main method of parametric modeling is discussed. Based on dynamic simulation software Adams, the parametric model of cone crusher motion system is established, and the contact force between thrust bearings is defined by Hertz elastic collision theory. Based on the parameterized model of motion system, the virtual prototype model of cone crusher is completed by using CAD software Pro/E. The curves of the rotation speed of the moving cone and the load of the eccentric sleeve with time are obtained by the simulation analysis of the model, and the feasibility of the model is verified by comparing with the theoretical calculation results. The relation function between the inertia force and inertia torque produced by the moving cone pendulum and the rising height of the hydraulic cylinder is obtained. Through the parametric analysis function of ADAMS, the influence of the rising height of the hydraulic cylinder on the performance of the crusher is analyzed, and the change of the motion characteristic of the point on the moving cone with the rotation speed and the eccentric angle of the eccentric shaft sleeve is studied. It has guiding significance and reference value for crusher structure design and parameter determination.
