  4. Abstract:
  5. In automobile painting industries, new automobile body products frequently should be tested in order to determine the actual thermal behavior of a paint curing process before starting mass production. During the hardening processes of dipped paint coating, applied in the electrophoretic enameling process, or top paint coating, applied in the final coating process, the automobile body must be warmed up according to the specific paint manufacturer curve. Consequently, prediction of car body temperature during the curing process may be vital in the design and performance analysis of the paint ovens. Numerical simulation of these processes may reduce expensive and time-consuming experimental procedures. In this research, a novel semi-analytical approach has been developed to predict the car body temperature during the curing process. Considering energy balance for each part of the body, a set of nonlinear differential equations has been extracted, which are related to the oven type and the heating zone. These equations may be solved numerically to find the transient temperature profile of the car body, provided that the required parameters are measured through experimental investigation. The results show that the present model predictions are in reasonably good agreement with experimental data, and this can be used as a robust efficient approach to distinguish overall thermal behavior of the car body during curing process. This research and its results may be useful in getting better understanding of the heat transfer mechanisms in the paint curing ovens and in optimizing their structures
