摘要
建立了履带车辆冷却风道三维模型与风扇蜗壳CFD分析模型.以空气流动阻力最小为目标,蜗壳几何尺寸为约束条件,提出了计算流体力学与遗传算法相结合的蜗壳结构优化方法.将优化后得到的三维模型与初始模型进行CFD对比,优化后的蜗壳空气流动阻力比优化前减小了9.73%,总空气质量流量增大了2.51%.
Firstly,the 3D model of cooling wind tunnel,together with CFD analysis model of fan volute,is established for tracked vehicles.By treating the minimum air flow resistance as objective and volute geometric dimension as constraint,the volute structural optimization method is proposed with integration of computational hydrodynamics and genetic algorithm.Afterwards,the optimized 3D model is compared with the initial model,whereas the air flow resistance is decreased by 9.73%,and overall air mass flow rate is increased by 2.51%.
