In this activity you create a new study, Study 1 - Event Simulation, to evaluate the strain experienced by the steel metal slab as it is reduced in thickness by 25%. To set up the study you:
Open the starting shape model, Plate Rolling in the Z up direction, from the Basic Training folder in the Data Panel.
Identify a personal project in which to save the model.
Identify or create a folder in which to save the model.
Switch to the Simulation workspace and select Dynamic Event Simulation as the new study.
Click on the Change Workspace drop-down menu at the top left end of the toolbar and select Simulation.
In the New Studies dialog box, select Dynamic Event Simulation.
While still in the New Study dialog, and using the information in the tutorial introduction, calculate the time required to move the steel slab under the roller.
The Event Duration is the time required to move the 100 mm long steel slab under the roller. The angular velocity of the roller is 314.159 rad/s, or 3000 RPM. The tangential velocity at the bottom of the roller, then, is calculated as:
Tangential velocity = radius x angular velocity
or
Tangential velocity = 175 mm x 314.159 rad/s = 54978 mm/s
When the steel slab engages with the roller, the friction between the it and the roller provides the steel slab with the same nominal velocity of ~55000 mm/s. To move the 100 mm long steel slab through the roller, traveling at ~5500 mm/s takes:
Event Duration = length (mm)/ velocity (mm/s)
Event Duration = 100 (mm)/ 55000 (mm/s) = 0.002 s
If we set our duration to 0.002 s, the steel slab will travel approximately 110 mm.
In the New Study dialog set the Event Duration as calculated.
In the upper right corner of the large thumbnail image, click Settings to access the Settings dialog.
The General settings appear initially.
In the Settings dialog type 0.002 s in the Total Event Duration field.
Change the Number of Result Intervals to 20, then create the study.
In the Settings dialog, type 20 as the Number of Result Intervals.
Click Back to apply the changes.
In the New Study dialog, click Create Study to create the study and close the dialog.
Check the units system and change it to Metric (SI), if necessary.
In this activity, you switched to the Simulation workspace to create a Event Simulation study, and then you defined its parameters. You
