摘要:

以某公司生产的BA01型车用散热器支撑骨架为例,结合刚、强度落球试验来分析不同配比玻璃纤维增强聚丙烯复合材料对其结构强度、刚度的影响,并通过Isight软件构建Kriging近似模型对BA01型车用散热器支撑骨架进行结构分析与多目标优化。结果表明,当玻璃纤维含量为42%(质量分数,下同)时,玻璃纤维增强聚丙烯复合材料的综合力学性能最适用于作为BA01型车用散热器支撑骨架的制造材料;骨架的主梁厚度、翼板厚度对其疲劳寿命性能影响程度最大,且具有正效应;通过Kriging模型优化了主梁厚度、翼板厚度等结构参数值,实现骨架疲劳寿命增强和质量降低的多目标优化设计。

Abstract:

Taking a BA01-type vehicle radiator support frame as an example, the effect of the polypropylene/glass fiber proportion in the composites was analyzed by a combination of computer software simulation and the relevant tests. The structural analysis and multi-objective optimization were also performed by constructing a Kriging model through the iSIGHT software. The results indicated that the comprehensive mechanical properties of polypropylene/glass fiber composites were most suitable for the production of vehicle radiator support frame at the glass fiber content of 42 wt%. The main beam and wing plate thicknesses exhibited the greatest influence on the fatigue life of vehicle radiator support frame. The structural parameters including the main beam and wing plate thicknesses were optimized by the Kriging model, and the multipurpose optimization design was realized for the enhancement of fatigue life and the weight reduction of this vehicle radiator support frame.

Key words: polypropylene, glass fiber, vehicle radiator support frame, multiobjective optimization
