In order to study the key technology involved in the digital mock-up research and development of complex products

aeroengine is taken as example to analyze the methods of modeling parts

assembly and associated design in the digital prototype. Firstly

3D models of aeroengine parts are established through the CAD software. Then

for the purpose of studying the lightweight

constrains

interference and other problems occurred in the assembly process

the sub-assemblies and full assembly of the engine prototype are conducted based on those 3D models. Finally

by means of utilizing WAVE technology

the associated parametric design of the blisk is achieved.By replacing the physical prototype with the digital mockup

it promotes the design and manufacturing development of high-quality

high-efficiency and low-cost products.
