摘　　要：为研究高速履带车辆稳态转向载荷比的变化规律,根据履带车辆转向过程中履带与地面之间的剪切应力-剪切位移关系,建立了稳态转向平衡方程和稳态转向载荷比模型。分析了履带车辆转向功率及整车转向载荷比随转向半径的变化规律,履带滑动对转向载荷比影响。最后对某高速履带车辆开展了稳态转向试验,进行数据处理和对比验证。结果表明:整车转向载荷比试验数据与理论计算结果有很好的一致性,验证了转向载荷比模型的准确性。In order to study the change of steady-state steering power ratio of high-speed tracked vehicle, the equationsare established and solved by iterative algorithm according to the relationship between shear stress and sheardisplacement; the model of steady-state steering power ratio is established as well. The relationships between power ratioof the whole vehicle, steering power and steering radius are analyzed, and the skidding influence of the track on thepower ratio is analyzed. Finally experiment of steady-state steering is carried out. Test data and the theoretic calculatedresults are compared, and the result shows that they fit well, which proves the accuracy of model of steering power ratio.
