Running safety trait analysis of tracked vehicle transiting unilateral obstruction

Based on the accident that the tracked vehicle rolls over when rapidly passing the unilateral obstruction, this paper analyzes the system using the system-theory and the kinetic methods on the safety trait of the process that the tracked vehicle pass rapidly through the unilateral-obstruction. The state equation of running trait that the rapid tracked vehicle shows in the passing of unilateral-obstruction is established, as well as the mathematical expression analyzing the process. Using the calculating tools, the analysis and calculation of the numerical values from each process, the parameters of different training roads and different muzzle velocity is completed, and the correlative figures are also protracted. The results indicate that if the parameters of training road change, the critical numerical values differs. That is to say, bifurcation point and mutation point are different respectively. The analysis not only provides the theory foundation for preventing the accident of passing obstruction by one side of tracked armored vehicle, but also is of high practical value.
