Parametric Design And Virtual Prototype Study Of Teeth Roll Crusher

The crusher is the indispensable equipment used to crush materials in many industries. In order to break through the traditional design method of tooth roller crusher, the virtual prototype system of roll crusher is established in this paper, with the application of which, the simulation analysis and parameter design of crusher were carried on.In this paper, with a strong teeth roll crusher as the research object, the complete model of it was established. And the model has passed the assembly interference detection. With the help of VC++ 6.0 and Pro/TOOLKIT, the parametric variant design of jaw crusher teeth plate was realized, laying a good foundation for the rapid design of products.The three-dimensional model, established by using the software Pro/E, was successfully imported into ANSYS Workbench for static analysis of it. According to the analysis results, three kinds of schemes to strengthen the weak part of roller gear were put forward.Through analysis and comparison, the ideal plan was ultimately determined.With the help of ADAMS software the kinematics and dynamics simulation of crusher was done. Firstly, through the analysis of the motion characteristics of crusher, the work processes of it stick out a mile, that has through the movement interference detection. Through the comparison of contact force of three different materials, it provides the basis for design of crusher for selection of crusher motor power. The contact force and the theoretical results of the extrusion force calculation are very close, which verify the theoretical simulation of virtual prototype of the system and the result is reliable and effective, but also reflects the theoretical analysis method of teeth plate force is feasible.Based on the similarity theory, the reliability of the virtual prototype system was evaluated. The system similarity was found by using the similarity analysis method, which is calculated by building similar elements and getting the values of these elements. The similarity of the system is 0.844, which proved that the simulation results of virtual prototype are reliable.
