Outline
This paper used the Synchronization Engineering (SE) analysis method to comprehensively evaluate the fixed engine hood scheme, and proposed 2 process schemes, i.e., the traditional scheme of passing through the paint shop using the hinge tooling, and the scheme of passing through the paint shop with the hood fixed and opened at a certain angle. Comparing the impacts of each scheme on manufacturing cost, anti-corrosion impact, deformation impact, appearance impact, assembly impact, etc., it is determined that a certain angle of fixed opening is the optimal scheme. Through the Alsim simulation software, the problems of gas and liquid accumulation of the engine hood after opening at a certain angle, the influence of deformation control and the influence on spraying appearance were analyzed, and the opening angle of 30° was determined as the best scheme.
