Abstract


In the the academic echelon and features research directions Fund of Natural Science Foundation of Gansu Province and Lanzhou University , launched a leveraged the virtual development of precision cutting device , a new structural model for precision cutting device . Learn shear devices already developed technology, further analysis of the precision cutting device works to closed structural principle is based on the use of computer CAD and CAE software , combined with the virtual prototyping technology , Φ25 Q235A bar , for example , design leveraged precision cutting device . The results show that : the leveraged precision cutting device structure is simple , easy to use , complete bar precision cut ; application of virtual prototyping technology in product development of the irreplaceable role to intervene so that the design of the virtual prototype process at a glance , to speed up the development cycle , the development cost , laid the theoretical foundation for the future towards R \u0026 D jobs . The work and achievements of this article : the content and conclusions of the subject from the angle of the structural principle : to discuss the radial clamping precision cutting device has the ability to withstand high loads and meet force closed structure requirements , the introduction of the principle of leverage to establish leveraged structure of the shear mechanism model . The combination of Pro / E modeling software to complete parts of virtual modeling and virtual assembly . Content and conclusions of the topics from the point of view of product development : With CAD / CAE / PDM software using PRO / ENGINEER 3D virtual modeling , ADAMS simulation environment , a the shear device from digitized entity modeling to virtual prototype simulation The virtual development work . Single database and correlation by Pro / E software , set up parts development module ; using Pro / E assembly module connections and constraints imposed during assembly , the shear device assembly simulation . Direct link with some professional software design environment for the analysis and optimization of the whole work convenience . Achieve the transformation from the solid model of the cutting device to a simulation model , and the conversion of the shearing machine assembly 3D models , dynamic simulation model of the three-dimensional simulation of the cutting device , and analysis of simulation results , verify the agency 's reasonable .
