Goal

Review past simulation files used to pass VDR (primarily MS14, but could look at MS12) and compare them to the current simulation.

If time permits, insert geometry of current chassis into past simulation file/setup to see if results stay the same.

Folder Path: D:\Users\Roo\Documents\GrabCAD\MSXIV sims\MS-CHASSIS

File Names:

1. 2019-11-30_FINAL.wbpj - finalized project file with the structural BP.

2. 2020-03-31.wbpj - project file with the BP being considered less structural (catamaran tubes added).

3. August25_Rev5.1.wbpj - Current iterative solution with reinforcements and non-structural BP

Outline of Settings:

• Project Workbench

• Engineering data

• Geometry (Spaceclaim)

• Model

• ACP Pre

• Static Structural (Specific Case Models: B-pillar, Side 60, Top 30)

Comparison of Simulation Settings

Conclusions

Project Workbench - naming convention varies, but the set-up remains similar (other than the fact that File 1 has ACP Post for each case)

Engineering Data - This info either uses default values from Ansys or is copied over from previous simulation files (i.e. are the same). (Focusing on 4130 steel and structural steel for now)

*Geometry - This is the main area in which our current set-up differs from previous files.

• removal of BP and addition of reinforcements

• removal of rear passengers mass

• currently seeing 97 beam profiles rather than 6 (likely due to duplicates, but should sort this out)

* Model - Settings are similar except for the following:

• Connections (currently have about half the number of contacts compared to previous files)

ACP Pre - Files appear to have similar settings. (wasn’t looked at too closely)

Static structural - These settings (acceleration and fixed support) are the same as in previous files.
