By simplifying the triangular tracked engineer vehicle into dynamic model of half-tracked vehicle with five freedom degrees which includes four vertical jumps and one rotation, a corresponding dynamic differential equation is set up to each degree of freedom. A method of road roughness simulation, based on the time series of White Noise, is also represented and then verified. The simulation analysis of the tracked vehicle ride comfort is built on MATLAB/SIMULINK, based on the incentive signal of an imitated road. The simulation results show that the method that White Noise generated road roughness is applicable and prove efficient in the ride comfort research of the triangular tracked engineer vehicle. Thus a theoretical foundation is established for the optimization for ride comfort of the triangular tracked engineer vehicle.
