| The work aims to conduct the numerical simulation analysis on the changes in vehicle deck temperature and cabin air temperature caused by solar radiationunder the conditions of outdoor training of special vehicles during summer and establish a numerical simulation model for the relationship between solar radiation intensity, vehicle deck temperature, and cabin air temperature, which will provide technical support for the next step of environmental temperature control of special vehicle cabins. Fluid dynamics numerical simulation technology was utilized to establish a model for the relationship between solar radiation intensity and deck temperature of special vehicle, the distribution law of surface temperature on the vehicle deck was obtained and the simulation results were compared with experimental results. By establishing a simulation model for air temperature in special vehicle cabins, the change law of air temperature inside the cabin was analyzed and the simulation results were compared with measured results to verify the accuracy of the simulation model. The simulation results of the relationship model between solar radiation intensity and vehicle deck temperature, as well as the numerical model of cabin air temperature, were compared with the experimental results. The maximum errors were all less than 10%, indicating the reliability of the numerical simulation model.The relationship model between solar radiation intensity, vehicle deck temperature, and cabin air temperature has been established by fluid dynamics simulation methods, which will provide a theoretical basis for the design of cabin temperature control system. |
