Abstract: With the localization of foreign capital heavy truck and the new force of domestic heavy truck, the competition of heavy truck is becoming more and more fierce. As dimension engineers, we should do our best to do a good job of dimension matching, so as to enhance the product appearance quality competitiveness. Through the problems of gap & flush and assembly in the dimension matching of interior and exterior decoration of a heavy truck cab, this paper analyzed and reflected on visual perception, datum, dimension chain, checking fixture, dimension flow and so on. The conclusions are as follows: the quality of pre-dimensional synchronization work, such as style seaming, datum and structure synchronization, has a great influence on the dimension matching. Therefore, only if the pre-dimensional synchronization work is done well, the dimension matching work can be carried out smoothly, so as to rapidly improve the appearance quality level of heavy truck cab and enhance product competitiveness.
