Truss AnalysisTruss AnalysisIntroductionThis report is writing about using the ANSYS 14.5 to help optimize the structure. To construct a structure in ANSYS, the most important thing is to define the node locations and the relations between nodes and elements. Each node, element, and cross-section area has to be matched up. All the data need to be entered in a text file. After the structure has been built, all the displacements on nodes and stress on the elements have to be solved. Use solutions to improve the structure. The essential processes are coordinating every node with every element appropriately, and analyzing the results to decide the best approach of optimizing the structure. The technical difficulty is the confliction between minimum displacement and lightest weight. To satisfy the requirements, the optimization should compromise in a reasonable range. To find the best approach, the stress of each element is used as references to increase or decrease the cross-section area. For balance the minimum displacement and lightest weight, the bars with small stress can be removed from the structure or reduced to smallest cross-section area to minimize the weight; and the bars with large stress have to be increased the cross-section area to decrease the displacement. Results The element properties, force and constrains on the structure shown in the table 1 below. Table 1.
