dc.description.abstract针对某装载机机罩存在质量大,有开裂现象等问题.以体积和频率为约束,以各工况载荷下结构的刚度最大作为目标函数,依据固体各向同性惩罚(SIMP)理论,采用带权重的折衷规划法对机罩结构进行多目标拓扑优化,并依据优化结果对机罩重新设计.结果表明,优化改进后的设计模型,既减轻了结构质量,又提高了结构的动、静态特性.
dc.description.abstractMulti-objective topology optimization for the loader hood under multiple loading conditions is studied with the maximum stiffness as objective,the volume and frequency as constraints,and based on the solid isotropic material with penalization(SIMP) theory and weighted compromise programming approach.The results show that the improved design of the hood not only reduces the structural weight but also meets the dynamic and static characteristic requirements.
