[Example] Linear static analysis considering initial bolt load
Simcenter Femap with Nastran
Linear static analysis using beam elements and bar elements for bolt connection parts!!!
**Case Overview** ■Product Name: Simcenter Femap with Nastran ■Industry: Mechanical Components Simcenter Nastran allows for various analyses considering pre-tensioned bolts (linear static analysis, nonlinear static analysis SOL601, linear buckling analysis, etc.). Using the Simcenter Femap interface, modeling of bolt connections with beam elements, bar elements, and solid elements, as well as the setting of bolt loads, can be done easily. This case modeled the bolts with bar elements and solid elements and compared the results from both. Two brackets with a surface static friction coefficient of 0.15 were fastened with M10 bolts. The axial force was set to 150 kgf, one side was fixed, and linear static analysis was performed (Figure 1). From the comparison of the results of the bar elements and solid elements, it was found that the maximum and minimum Mises stress and maximum and minimum displacement of the two brackets were the same for both methods. ● For other features and details, please refer to the catalog.
