Based on Recur Dyn software, the virtual prototype of D320E electric drive crawler-type bulldozer is built. The dynamic simulation analysis under two different straight-line working conditions of dry sand and clay pavement is carried out. The research results show that the variation law of the mass center of bulldozer with the working resistance under different working conditions. The working stability of the bulldozer can be improved through the reasonable layout of the mass center of bulldozer, which provides a reference for the optimal design of the bulldozer.
