Upcoming Deadlines

Dynamics:

Updates

• General:

  • Slept and traveled not much work done

• Unsprung:

  • Unsprung was traveling the entire time

• Suspension:

  • Suspension got a mix of some CAD and force matrix but also some weren’t able to get work done.

• Steering:

  • Steering got upper and lower steering CAD to exist

Week Plan

• CAD for every part should exist by Thursday

• Unsprung:

  • Sim the hubs

    • Redesign

  • Break button dimensions and forces on the rotor when we lock up

  • Figure out how to properly use SKF simquick pro
