Notice of RetractionThe temperature modeling of the moving armored vehicle based on finite element method
Due to the decline of the viability and battle effectiveness of the electronic countermeasure armored vehicle caused by intense infrared radiation (IR), the temperature model is built for the IR characterizations of moving target. While taking the effect of radiation, convection and heat transfer into consideration, the mathematic description and simulation of the temperature model are carried out with finite element method (FEM) in the processes of sub-domains partition, node determination, control equation construction, boundary condition determination, equation discretization and iterated calculation. The comparison and analysis of the temperature distribution of typical parts between the simulated results of the FEM and the actual measured value are carried out with the same parameters. It indicates that the results with the application of the FEM approaches the actual measured value more with a better precision.
Calculation of the Radioactive Transfer Coefficient by Iteration Method in Heat Analysis
To get another method of calculating radioactive transfer coefficient, based on the concept of angle factors, the radioactive transfer coefficient was calculated by iteration method in light of the theory of energy conservation and of Lambert body assumption. The method was applied to the simulation of infrared radioactive fields of sea object and. It was proved that high efficiency was obtained and the difficult was decreased.
