摘要
在有限元分析的基础上,采用材料替换及结构拓补优化的方法对某发动机活塞进行轻量化设计.利用SolidWorks建立活塞三维模型,将活塞原始材料1015铝合金替换为7075铝合金;运用Altair Inspire有限元分析软件分别对两种材料的活塞进行静力学分析及模型质量测量,采用拓扑优化方法进行结构优化.仿真结果表明:优化后活塞质量减轻了 64%,活塞的最大应力减小了 12%,安全系数提升了 3.7.
Abstract
Based on the finite element analysis,the lightweight design of an engine piston is carried out by the methods of material replacement and structural topology optimization.SolidWorks is used to establish a 3D model of the piston.1015 aluminum alloy,the original material of the piston,is replaced by 7075 aluminum alloy.Altair Inspire is applied to conduct static analysis and model mass measurement for the pistons of the two materials,and structure optimization is carried out by topology optimization method.The simulation results show that after material replacement and structure optimization,the piston mass is reduced by 64%the maximum stress of the piston reduced by 12%and the safety factor increased by 3.7.
