According to the excavator working principle and structure characteristics, the use of threedimensional modeling software Pro / Engineer part to establish a threedimensional model of the excavator, and on this basis part of the assembly, interference detection, motion simulation and other advanced puteraided design , the plexity of the image to show the excavator to the user, so that designers in the design phase can clearly see the results of the final product, to detect design problems. Not only reduces the workload but also saves money for the new foundation for the development of products to help enhance product development capabilities.
