Analysis and Simulation on Dynamic Stress of Tracked Vehicle Sprocket

TIAN Zheng,CHEN Bing,YIN Zhong-jun,WANG Wen-rui(Mechanical Engineering School of University of Science & Technology of Beijing,Beijing 100083,China)  
In order to research the dynamic stress of the tracked vehicle sprocket,this paper established a high-speed tracked vehicle dynamics model,in which the time loads of sprocket was simulated during the vehicle is running at 60km/h on the D class road.We established the "trackboard-sprocket" models of the single tooth in mesh and multiple teeth in mesh.The dynamic stress of the sprocket's gear ring was acquired by analysis.Simulation results show that the stress of tracked vehicle sprocket's gear root and the fixed gear bolt hole are larger,and the stress concentration is observed at the edge of the teeth.The other gear tooth's forces only increase the stress of the fixed gear bolt hole compared with the results.The simulation results provide the calculation basis for the optimization of the high-speed tracked vehicle system.
