titleNotes:

Goal

  • Previously, we fixed the back face of the collision object and accelerated the chassis into the object. Fixing this face fixes the entire body of the object as it is a single solid body.

  • Rev 4.0 attempts to fix the chassis and accelerate the object into the chassis.

Simulation Set-up

  • The following steps were used to set up the simulations (see sub-page for more details)

    • Suppress existing 5G acceleration

    • Suppress the existing fixed support on the collision object

    • Add new fixed support to the chassis

    • Add the equivalent force

    • Add displacement constraints to control the motion of the collision object if needed

Conclusions

  • stress results can change drastically depending on the fixed supports selected (much higher or much lower)

  • This setup can be used to our advantage to obtain lower stresses however, we will need to justify the fixed supports we choose.

  • Overall, it might be best to stick with the fixed object setup to avoid ambiguities or any issues getting the VDR approved.
