The aim of this article is to demonstrate how to define the Preload Axial force applied to the set of beam, truss and spring elements.
This feature is available from Radioss version 2024
Software used:
- Altair Radioss version 2024.1 & above
- Altair HyperMesh version 2025.1
Model setup
We considered five different types of element (beam, truss and spring elements) as shown below which support the /PRELOAD/AXIAL load card in Radioss.
The properties for truss, beam and spring elements and model setup are explained in the attached document.
Results
Summary
- This study demonstrates how to define the Preload Axial force applied to the set of beam, truss and spring elements.
- The Preload Axial force feature keyword available from Radioss version2024.
- All the element set used for defining load case need to defined with keyword /SET/GENERAL/ as shown in page10.
- This application can be used to tightened the cable between two poles.
- This feature can be used to preload a bolt modeled with 1D elements during the preloading phase.
