基于遗传算法的某汽车外形空气动力学优化
Aerodynamic Optimization Based on Genetic Algorithm of Automobile Shape
摘要
Abstract
Automotive exterior aerodynamic optimization design is a multi-objective optimization de-sign field. The basic objective of solving multi-objective optimization problem is to get the best Pareto solution set. First,we established the simple model and got parameterization of front raxe angle(an-gle 1),front windshield angle(angle 2),rear windshield angle(angle 3)and rear raxe angle(an-gle 4). And we obtained sample points with Latin hypercube sampling,and then simulated the aero-dynamic drag and lift of the samples by using FLUENT software. Using genetic algorithm data,we had iteration and found the optimum angle assembly for the best aerodynamic by finding the Pareto so-lution.关键词
