Transcript
00:04
Within the Dynamic Simulation environment in Inventor,
00:07
you can export a part and specify the load-bearing faces to be used in the subsequent stress analysis.
00:14
To start, from the Quick Access Toolbar, click Projects.
00:18
In the Projects dialog, click Browse, navigate to where the project files are saved, select Assy, Chassis, Front DS.ipj, and click Open.
00:31
In the Projects dialog, click Done.
00:34
From the Quick Access Toolbar, click Open, select Assy, Chassis, Front DS_002.iam, and click Open.
00:43
In the Model browser, Model States folder, right-click Dynamic Simulation and select Activate.
00:50
On the ribbon, in the Environments tab, Begin panel, click Dynamic Simulation.
00:56
The Simulation Player opens.
00:59
In the Model browser, collapse the Grounded item.
01:02
In the graphics window, select the hydraulic cylinder assembly.
01:07
This highlights the applied Standard Joints of Revolution and Cylindrical in the Model browser.
01:12
Right-click Cylindrical: 2 and select Properties.
01:17
In the Joint Properties dialog, on the dof 2 (T) tab, click the Edit joint force icon.
01:23
Select Enable joint force.
01:27
Click the arrow next to the field below and select Constant value.
01:33
Enter a constant value of 41500 N, and then click OK.
01:40
You can now export a part to the Stress Analysis environment.
01:44
On the ribbon, in the Dynamic Simulation tab, Stress Analysis panel, click Export to FEA.
01:51
Finite Element Analysis (FEA) associates the necessary data with the appropriate assembly files for analysis.
01:59
In the graphics window, select one of the brackets for the hydraulic cylinder assembly.
02:04
A warning message appears indicating that the selected part is in a non-flexible subassembly.
02:11
Click OK, then cancel out of the Export to FEA dialog.
02:16
Select the complete subassembly, right-click it and select Flexible.
02:22
Click Export to FEA again, and then re-select the bracket.
02:27
In the Export to FEA dialog, click OK.
02:31
In the FEA Load-Bearing Faces Selection dialog, you need to complete the joints.
02:36
Under Joints to complete: Load Bearing, select the Welding option.
02:41
In the graphics window, select the large inside circular face of the bracket.
02:47
In the dialog, select the Revolution option, and then select the small inside circular face of the bracket.
02:54
Click OK.
02:55
To run the simulation, in the Simulation Player, click Run.
03:00
To interrogate the results, from the Results panel, click Output Grapher.
03:06
In the Output Grapher, expand Standard Joints > Cylindrical:2, and then the Force folders.
03:13
Select Force.
03:16
Under joint Cylindrical:2, deselect position P[2], which removes P2 from the columns on the right side of the grapher.
03:25
On the right side of the grapher, in the Time(s) column, select time step 1.00000 to export it.
03:32
In the graph, double click the 0.5 second time mark.
03:37
Select time step 0.50000 to export it.
03:41
Repeat these steps for the 0.75 time mark in the graph and the Time(s) column.
03:48
Notice that these three time steps have been added to the Export to FEA folder in the Output Grapher.
03:55
Close the Output Grapher.
03:58
To exit the animation in the Simulation Player, click Construction Mode.
04:03
Be sure to Save your work.
