基于DOE的通风式制动盘散热性结构优化

为优化通风式制动盘的散热性,运用仿真软件建立制动盘热机耦合模型,通过热机耦合仿真考察制动盘散热性和研究通风式制动盘单侧盘厚、加强筋数量及加强筋宽度3个因子对制动盘散热性及制动盘质量的影响,来确定最经济的制动盘方案.结果表明,优化方案不但提升了制动盘散热性（最高温度降为182.5℃）,而且减轻了质量（质量减轻了0.117 kg）,提升了经济性和轻量化,为制动盘设计提供了借鉴.

Structure Optimization for Vented Brake Disc Heat Dissipation Based on DOE

A brake disc model has been built using software 1o improve the heal dissipation. Thermal dissipation of brake disc was checked using thermal-mechanical coupling simulation. A beneficial scheme of brake disc was determined by studying three factors, such as unilaleral plate Ihiekness, numbers of stiffening rih and the widlh of stiffening rib which influenced the thermal dissipation and mass of the brake disc. The optimized svheme not only improves the heat dissipatiml of brake disc, but also achieves the purpose of lightweighl.
