SS-T: 4025 Modal Prestressed Analysis
Apply prestress conditions to modal analysis.
- Prerequisites
- Some features used in this tutorial are only available in SimSolid Advanced version. Please switch to Advanced to complete this tutorial.
- Purpose
- SimSolid performs meshless structural
analysis that works on full featured parts and assemblies, is tolerant of
geometric imperfections, and runs in seconds to minutes. In this tutorial,
you will do the following:
- Learn how to setup prestressed modal.
- Compare prestressed and non-prestressed modal results.
- Model Description
- The following model files are needed for this tutorial:
- Crankshaft_Prestressed.ssp
Open Project
- Start a new SimSolid session.
- On the main window toolbar, click Open Project .
- In the Open project file dialog, choose Crankshaft_Prestressed.ssp
- Click OK.
Create Modal Analysis
Create Immovable Support
Create Hinge Support
Create Structural Linear Analysis
Copy Supports to Analysis
- Under the Modal 1 analysis, right-click on Immovable 1 and select .
- Right-click on Hinge 1 and select .
Create Rotational Inertia
- From the Structural 1 Analysis Workbench, click .
- In the dialog, click the Select a cylinder radio button and select the cylinder Hinge 1 is applied to.
- For Angular velocity, enter 5000 and change the units to RPM.
- For Angular acceleration, enter 50 rad/sec^2.
- Click OK.
Create Modal Prestressed Analysis
Edit Solution Settings
- Double-click on Solution settings: for Modal 1.
- In the Solution settings dialog, for Adaptation select Global+Local in the drop-down menu.
- Click OK.
- Right mouse click on solution settings and select Apply to all analyses in the current design study to apply the global+local adaptation to all other analyses in the study.
