The Study of Cartridge Inserted Valve Integrated Block Virtual Design Based on 3D

With the core of virtual technology, through the development of 3 D CAD software SolidWorks using Visual Basic, the virtual design of cartridge inserted valve integrated block was realized, the laborious, time consuming and error-proneness problems during the hole series network design of cartridge inserted valve integrated block were solved. The system architecture, the digitized method of hydraulic skeleton drawing, the integrated package design and check method were presented, through the establishment of characteristic library, the three-dimension parameterized modeling was realized using AetiveX Automation technology, the solutions of the virtual design of cartridge inserted valve integrated block were put forward. Through the interference check to the cartridge inserted valve integrated block assembly, the successful rate of the design can be in creased.
