2. ANSYS Workbench Beam Shell Structure Spectral Analysis (I) Beam Shell Modeling
Spectral analysis is a method for calculating the response of structures under various frequency transient excitations.
. This analysis involves excitations such as earthquakes and aircraft noise. This article takes the beam shell structure as an example to provide a detailed introduction to the spectral analysis method of ANSYS Workbench. When the aspect ratio of the structure exceeds 10, the stress along the length direction becomes the main analysis object, and the cross-section remains unchanged. At this time, beam elements can be used for analysis. In ANSYS Workbench, Timoshenko beam elements are used by default, including Beam188 elements without intermediate nodes and Beam189 elements with intermediate nodes. The shell elements include Shell181 elements without intermediate nodes and Shell281 elements with intermediate nodes. The 3D model and related parameters of the beam shell structure used in this case are shown in the figure. The model framework is simulated using Beam188
(1) There are multiple methods for modeling beam elements. In this case, the point → line method is used for modeling. A TXT document is created, named Point, and coordinates (in meters) are entered according to the relevant dimensions in the first section. The document content is shown in the figure. Open ANSYS Workbench, select Geometry, double-click the Geometry cell, and enter the Design Modeler (DM) program.
(2) Click on the menu bar 【 Point 】, set 【 Details of Point 】 → 【 Coordinates File 】=Import Point document; Set 【 Details of Point 】 → 【 Coordinates Unit 】=Meter, default for the rest, then right-click 【 Generate 】 to generate the point model as shown in the figure.
(3) Click on the toolbar 【 Concept 】 → 【 Line From Point 】 to generate 【 Line1 】, click 【 Line1 】, and set 【 Details of Line1 】 → 【 Operation 】=Add Frozen; Press and hold [Ctrl] on the keyboard, click on points
1 and 2 (as shown in the figure), click on the navigation bar [Point segments]=Apply, click on [Line1], right-click on [Generate].
(4) Click on the toolbar 【 Concept 】 → 【 Line From Point 】 to turn the Shenghe bend into 【 Line 】, click 【 Line 】, set 【 Details of Line1 】 → 【 Operation 】=Add Frozen; Press and hold the [Ctrl] key on the keyboard, then click on point 1 → point
