Abstract


Funded research programs in Gansu Province, to carry out the virtual precision shearing equipment research and development. To the the the precision shearing equipment innovative design for the study, with radial clamping precision shearing equipment development goals, research innovative products virtual development theory, development the precision shearing equipment virtual design platform. The precision shearing equipment loads, required to have force closed structure complex stress state of the vital parts, feeding mechanism requires dynamic floating and other characteristics. Summarize the precision shearing equipment works, analysis of the precision shear structural features of the equipment and feed mechanism, discuss the precision shearing equipment work steps, and explore issues such as precision shearing machine equipment feeding mechanism works. To the feeding mechanism of the shear device for the study, to explore products virtual development lingjing environment and related technologies. Focused on virtual reality technology, modeling techniques, virtual assembly environment and feeding mechanism of the virtual development process and development platform. Relying on the focus on technology, virtual product development technologies such as parametric modeling technology, virtual assembly technology, simulation system, with the help of international popular high-end CAD / CAE / PDM software, create a Pro / ENGINEER - ADAMS virtual three-dimensional modeling and simulation environment, shearing machine feeding mechanism is modeled from digitized entity to the virtual prototype simulation (dynamics, kinematics simulation) and analysis of the virtual development work. Proposed the precision shearing equipment feeding mechanism virtual development characteristics entity parametric modeling technology and virtual assembly technology. Discuss feeding mechanism in Pro / E platform parts entity model Establishment PRO \\ E software of a single database and all related to sex, to establish parts development module; discuss the Pro / E's virtual assembly mechanism assembly constraints applied to achieve send material bodies in the initial assembly, analysis of the overall virtual assembly of the feed mechanism specific virtual assembly process and shearing equipment, focusing on analysis of the optimization problem of the slider assembly designed to eliminate interference floating rack. Precision shearing equipment feed mechanism work process simulation. Discuss the dynamic simulation analysis of the key technologies - virtual prototype technology, realized from the feed mechanism entity model to a simulation model of the transformation, achieve feed mechanism assembly body conversion of 3D models, to related dynamic simulation fixture and send material bodies of the three-dimensional simulation model analysis of simulation results, which lay the foundation for the optimization of the feed mechanism.
