Design Of Roots Blower CAD System Based On SolidWorks

As a dual rotor gas compression and transportation machinery, Roots Blower is widely used in various industrial fields. It has characteristics of numerous modifications, design calculations and repetitive jobs existing in the design process of Roots Blower. In order to enhance the design efficiency and quality, this thesis uses the Visual Basic Language in the secondary Development of SolidWorks, studies the design of Roots blower CAD system.This thesis analyzes various leaf type profile of Roots Blower, derives the actual profile parameter equation, studies Roots Blower various structural parameters and performance parameters and establishes the relationship between them. The paper studies SolidWorks secondary development system, introduces the OLE technology and the COM technology, elaborates objects accessing methods of SolidWorks API and interface technologies.Thesis gives overall analysis of the Roots Blower CAD system, plans the design goals of the system, designs the system operation flow chart; Using Parametric Design principles based on feature modeling technology. Using Visual Basic6.0 Language calling SolidWorks API interface function, through macro recording and modifying the key code, achieved the secondary development of the SolidWorks and established the system Database. It can automation design calculations of parameter and geometric modeling.Debugging and modeling experiments illustrate that it can complete three-dimensional model based on user input of the basic parameters. System has a amazing interface and can interact with users in a most convenient way. It can greatly enhance the design efficiency and quality of Roots Blower, shorten the product development cycles, reduce business production costs, and improve market competitiveness. It has a practical value.
