Abstract

With the increasing demand for high performance and energy efficiency in the mechanical industry, lightweight design has become a crucial direction in mechanical structure design. Topology optimization, as an advanced structural optimization technique, maximizes structural performance and reduces weight by rationally distributing materials, making it an effective method for lightweight design. This study systematically investigates the lightweight design method of mechanical structures based on topology optimization, combined with multi-objective optimization theory to achieve an effective balance between structural strength and stiffness.
Results show that topology optimization significantly reduces structural weight while improving the mechanical performance of components, promoting the development of mechanical design towards high efficiency and intelligence.
