【正文】 act： Loader is a kind of engineer machine that is widely applied in engineer project, which has wildely space, Aim to the problems that exist in traditional research way of loader, for example the research cycle is long, the cost is long, the cost is high and the performance test is plex etc, this paper leads virtual prototype technology into research of loader. The following research works are pleted: 1. The development foreground, the category and loader’s history is introduced, also the background of simulation technology e 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 pleted. 3. The simulated motion in Pro/E environment is pleted, 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 II 目 錄 摘 要 ....................................................................................................................................
