Research on the Turning and Pitching Performances of Articulated Tracked Vehicle

The mathematical models of articulated tracked vehicle were established for resistance torque solving and pitch analysis by taking the all-terrain articulated tracked vehicle for example,and the factors causing the resistance torque when horizontally turning were analyzed by the tracked vehicle turning principle and Bekker theory.The calculating method of friction between tracks and the ground and the calculating formula of soil resistance caused by the flank of tracks were given.The correctness of this analysis method was verified by test.The results show that this method can not only analyze the condition of the resistance torque for horizontal turning reasonably and effectually,but also provide theoretical basis for the design of articulated tracked vehicle.
