Optimization Design of Loader Engine Stents Based on ANSYS


Article Preview

Seeking the best layout engine scaffold materials is always the focus of the stent design personnel stent . This object of research in this article is the engine stent of a certain loader. the geometric structure model is created by Solidworks. On this basis, finite element model is created in ANSYS. Structure of stent is optimized topologically by using variable density of topological optimization algorithm in which bracket stiffness is been as the optimization objective and reduce the materials quality is been as the state variables. And stent is modeled secondly by using gotten the most optimal topological model. The stress and deformation of the improved stent of engine increased. But weight of stents is reduced by 8.7%.
