Dynamics Analysis And Simulation Research On Lmpacting Crusher-Compactor

With the infrastructure further,more finance is invested in the road remend.The construction machinery decide the schedule and the quality of the project. These machines are designed to achieve several tasks at the same time,and to be intellectualized.Impacting Crusher-Compactor has two purposes-Crushing and Compacting.Much attention is paid to it.But many domestic manufacturers produce it imitatly without credible theoretcis.Therefore,the mechanical properties of the quality performance and the capability of Crushing and Compacting are difficult to meet the destined effect.As a new technique of Computer-Aided Engineering(CAE), the advantages of Virtual Prototyping Technology are as follows .It can simplify and shortcut the design processes of the mechanical products,depress the cost more evidently,improve the quality and the system performance obviously.Impacting Crusher-Compactor is a spring-linkage mechanism which has 3 degrees of freedom.Firstly the paper analyzes the working principle,and many significant data which will be used in subsquent parts of the paper can be acquired by use of Visual Basic 6.0 procedure to determine the initial position.Secondly.the solid "Virtual Prototype Model is assembled by unit parts with Unigraphis NX,and the dynamic simulations are demostrated in UG/Motion environment,which cofirm the seenarios to be reliable.Thirdly,the Lagrange Equations are deduced in accordance with the math model of the machine.Combining with MATLAB Symbolic Math,the logic frame chart of the equations are illustrated in MATLAB/Simulink,and linked by Sferteflow.The simulation results are verified.Lastly comparing with the two methods,a conclusion is drawn that a different soft is taken at different stages to design reasonable mechine.
