Engine Hood Lightweight Optimization Design Based on Overall Satisfaction

Abstract:

CAE analysis on engine hood is conducted under five common working conditions in this paper. Considering lightweight material application status at present, three material substitution plans are determined. To make full use of material properties, draw up size optimization scheme based on volume target and displacement and frequency constraints. Determine the optimum thickness by conducting size optimization on engine hood with optimization tool-Optistruct, so as to realize lightweight design.Based on the introduction of a evaluation method for lightweight scheme selection based on overall satisfaction and taking the factors of weight, cost and performance into consideration, at last, determine the best lightweight scheme.
