| Abstract: | The article analyzes the current status of lightweight design of products,taking a crank arm structure as the research object and using finite element analysis software to solve the problem based on the statics results,topological optimization of the structure of the research object based on its statics results.The results were verified for the crank arm based on the data results.The comparative analysis of the thickness of the crank arm stiffeners by changing the static stress showed that the mass of the crank arm was reduced by 4.1%under the conditions of rigidity and strength.At the same time,part fatigue verification is carried out,lightweight and reliable design provide theoretical guidance. |
