Virtual design technology is based on computer simulation technology,which simulates the entire product development process in real-time and parallel during the product design stage.This article uses SolidWorks software as a platform and takes needle valves as an example to discuss in detail the methods and techniques of 3D modeling of parts,as well as common problems and solutions such as connection positioning and interference inspection in virtual assembly.Thus shortening the product development cycle,reducing development costs,and optimizing design quality have high reference value for product design and development personnel.
