Its overall performance depends not only onthe quality ponent, but also depend onthe mutual coordination ofall the parts. Inblade bulldozer, working device ponent. Its design parameters will impact onthe performance ofthe bulldozers. Based prehensive understanding oftractor 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 ofthe ponents hinged program and the calculation process. This paper also describes including the blade design and calculation, scarification ofdesign 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.
