Topology Optimization Of Structures With Thermal And Mechanical Loading

In this study, capabilities, performance, and limits of a new design field named topology optimization were investigated. Case studies under different loads and boundary conditions were evaluated. The case studies were selected by the purpose of illustration of the capabilities of topology optimization. In order to analyze the case studies with more complexity such as cantilever beam, both end fixed beam, dome shape under static and thermal loading, Optimization algorithms were used in the ANSYS software. Results showed reduced volume in final models are 66.29%, 52.88%, 50.054%, respectively. The mean value of stress in the Cantilever beam,both end beam and dome shape was increased 88, 800 and 6 Mpa, respectively. Also, the displacement level was increased 0.0001, 0.006 and 0.002 mm, respectively. In order to reveal the unexpected challenges and evaluation of optimized models, due to the presence of cavities in the body, Dome Shape model was selected and produced by additive manufacturing (FDM method). Results indicated that the output product has good dimensional accuracy and surface smoothness. By creating support structures that manually selected numbers and locations, 3D cavities were formed with good accuracy, indicate that there is a high potential for manufacturability of complex design parts without classical methods.
