Jaw Crusher Kinematics And Moving Jaw And Frame Of Simulation And Optimization

From a broken process point of view, crusher divided into coarse, crushing, grinding, broken in several ways. The jaw crusher is mainly coarse crusher.Jaw crusher is broken by the main means extrusion material, so the frame size and broken crusher cavity of the geometry of the performance of the crusher have a decisive influence.Based on the single particle breaking and single particle materials in crushing cavity classic five broken from discharging from mouth to assume conditions, in determining the pendulum jaw crusher work parameters to get basic size after, on the basis of pendulum in the jaw crusher entity surveying and mapping model as the research object, in complete top-down (skeleton design) the parametric model based on the single grain five times the theoretical calculation of broken on the basis of the parametric model to design. According to this model the kinematics and dynamics analysis and optimization analysis, realize the pendulum jaw crusher on the true meaning of the parametric design, obtained the kinematic and dynamic characteristics of actual design production work have significance. The main research work has the following several parts: 1. With3D software Pro/E of surveying and mapping in the entity model based on completed the entity of parameterized modeling work. Application Pro/E of top-down design (skeleton design) function, achieve the machine parameters of the model transfer, size automatically change of the model, automatic generation.2. The pendulum of jaw crusher model of the kinematics simulation research, to move the jaw tooth surfaces at the motion characteristics analysis, based on the dynamic jaw level characteristics of small trip idea, determine the dynamic jaw plate on the position of the minimum displacement levels and hang the reasonable selection of height.3. Through the main parameters of sensitivity analysis, the optimization analysis to determine the objective function, and further to crank shortest length and transmission Angle on the objective of maximizing the multi-objective optimization study to crank length on the target of minimizing the single objective optimization are obtained in institutions size optimization of model, which establishes the foundation for dynamics.4. On this basis, the pendulum will jaw crusher parameterization models through the Pro/E and ANSYS interface imported into the AN SYS.5. Build dynamic jaws and the stress of the frame model, based on ANSYS static analysis of learning.6. In order to seek the inherent agency the natural frequency of the organization, and to learn the vibration of the structure characteristics, the dynamic jaws and frame of modal analysis.7. Because pendulum jaw crusher dynamic jaw broken in the main process of the bear is the role of the impact load, so the its transient dynamic analysis, the dynamic jaw got of the dynamic properties.This paper has realized the pendulum jaw crusher movement simulation and optimization design, for practical production work to provide effective theory basis for promoting single grain materials under the theory of the pendulum broken jaw crusher finalize the design and production has the very vital significance.
