摘　　要：本文提出了适用于三履带机器非稳态转向特性分析的数学模型及求解方法，模型中考虑了履带宽度及履带接地面速度瞬心的偏移；可用于仿真三履带机器的非稳态转向性能。以具有一条转向履带的三履带机器为例，分析了在不同转向履带偏转角度下，机器的转向轨迹及动力学参数的变化规律。A mathmatical model of unstable state steering characteristic analysis of three track machine is set up and its solution is provided The model considers the width of track and the deviation of instantaneous centroid of track ground speed It can simulate unstaable state steering characteristic of three track machine Taking one steering track of three track machine as an example,this paper analyzes the changeable rule of steering trajectory and dynamic parameter of machine under variable turning angle of track
