Its overall performance depends not only on the quality of each ponent, but also depend on the mutual coordination of all the parts. In blade bulldozer, working device is an important ponent. Its design parameters will impact on the performance of the bulldozers. Based on a prehensive understanding of tractor structure and working principle,design tractor equipment and process simulation are intrduced. This paper describes the crawler tractor, the overall design Blade working device structure design of the various ponents hinged program and the calculation process. This paper also describes including the blade design and calculation, scarification of design and putation, the equipment hydraulic system design, pushing beam design and strength check, and calculates for the bulldozers resistance operations and design for process simulation system. The thesis plets with the design of the technical requirements of the crawler tractor attachments Keywords Bulldozer； Equipment； Transport ； Machinery Scraper IV 目錄 目錄 ....................................................................................................................
