The following research works are completed:1. The development foreground, the category and loader’s history is introduced, also the background of simulation technology come into being, developing status in local and the significance of virtual prototype technology is introduced.2. To brief introduce the Pro/E software which application in the field of engineering, the 3D modeling is used by Pro/E software, which is built and interferential test of assembly in Pro/E environment is completed.3. The simulated motion in Pro/E environment is completed, and the capability curve is reached.4. A rational choice for the hydraulic actuating cylinder.Keywords: Loader, Working mechanism, hydraulic actuating, Simulation technology, 3D modeling目 錄摘 要
