STRESS ANALYSIS AND MATHEMATICAL MODEL BUILT ON BULLDOZER''S SIX-DIRECTION SHOVEL
推土机六向铲的受力分析及其数学模型的建立

The load analysis of bulldozer includes the external load, and each component load of work equipment under the external load. The structure of bulldozer's six-oriented shovel is simplified, and the load analysis on its model is carried out. At the same time, the oil jar force, the reaction load of pushing peak frame and the reaction load of each joint point are analyzed. The work not only provides a basis for framework analysis of work device, but also for rigidity tolerance analysis.
