Simulation And Analysis Of Parametric Modeling For Virtual Prototype Of Cone Crusher

As a main equipment of crushing the materials, cone crusher is widely used in the industry of metallurgy, mining, building materials, electric power, chemistry and so on. Virtual prototypical technology can generate the virtual model of the equipment on the computer, and test its various performance. The application of the virtual prototypical technology to the design and research of cone crusher can make the design of production partly or even completely depart from the dependence on physical prototype. It has great significance to shorten the design cycle, to reduce the design cost and to improve the competitive power of enterprise.Through the study of kinematics and dynamics on cone crusher, the rotation speed of the cone under different working conditions and the movement characteristics of points on the cone are obtained. The inertia force and inertia moment of the cone and the eccentric sleeve under the process of rotary pendulum are computed by using differential element method. The influence of the size of the balanced block on the movement of eccentric parts is discussed and the effect of the different motion of the eccentric parts on the size of discharging mouth is analyzed. The conclusions that obtained can guide the design of the balanced block.This paper discusses the main methods of parametric modeling. Based on the dynamics simulation software ADAMS, the parametric model of the motion system of cone crusher is established and the contact force between the thrust bearing piece are defined by Hertz collision theory. On the basis of the parametric model of the motion system, making use of CAD software Pro/E, the virtual prototypical model of cone crusher is completed.Simulate and analysis the model, the time-varying curves of the rotation speed of the cone and the load on the eccentric sleeve are obtained, and compare the results with theoretical calculations to verify the feasibility of the model. The functional relationship between the inertia force and inertia moment of the cone under the process of rotary pendulum and the rising height of the hydraulic cylinder is obtained by calculation. By parametric analysis function of ADAMS, the influence of the rising height of the hydraulic cylinder on the performance of crusher is analyzed and the movement characteristics of points on the cone with the changes in speed of the eccentric sleeve and the eccentric angle is investigated. It makes guiding significance and reference value to the design of the cone crusher structure and the determination of parameters.
