Abstract:	In order to study the spatiotemporal distribution characteristics of dust concentration field during tank driving in typical battlefield environments, through the numerical simulation method, the Geometric modeling is established, and the discrete phase model is used to use the Computational fluid dynamics software Fluent to carry out numerical simulation calculation on the dust concentration distribution of typical particle sizes, ground roughness and different acceleration during the tank driving. The research results indicate that: Different particle sizes on the ground have a certain impact on the distribution of fugitive dust concentration. The larger the particle size, the greater the concentration of fugitive dust, and the smaller the impact on the distribution range of fugitive dust; The greater the roughness of the ground, the stronger the ability to stir up surface materials on the ground, the more particles driven by driving, and the corresponding increase in dust concentration generated by tank driving; The greater the acceleration of the tank during driving, the greater the range of dust distribution and the concentration of dust will also increase. The simulation research and results in this article have certain reference value for laboratory simulation of tank driving dust.
