Week 1
  • Lecture 1 (Tu, 1/19)  | last updated 1/19/16
    • Course Introduction | 01 Intro/Overview slides
    • Animations from slides: 
      • split mu | animation from CarSim simulation; illustrates loss of yaw stability due to lock up of rear wheels during braking on a split mu (friction) road
      •  icy yaw instabilities | video demonstrating loss of yaw stability by vehicles on icy bridge
      • big air | animation from CarSim simulation; extreme vertical vehicle dynamics with loss of contact
      • rover | bus | two different animations of ADAMS simulations of multibody vehicles; rover was a demo from MSC of a small robotic vehicle; the bus animation is for a model of a bus that has a 'tag axle', studied to evaluate tax axle influence on stability of steering
    • Review course syllabus, prerequisites, course materials, and homework and project requirements
    • Review problems in dynamics with solutions - these are some selected problems from Meriam and Kraige.  This is where we will begin next time, but show how these types of problems might be worked so we can build model simulations, solve for motion over time.  Here is the relevant chapter discussion related to those problems.

Week 2

Week 3 -

Week 4 -
  • Lecture 7 (Tu, 2/9) 
    • Recap relevant parts from Thursday's discussion, since so many of you missed that day.
      • models for longitudinal and lateral tire forces
      • bicycle model
      • reduced model - no effect from traction / braking forces
    • Stability of the vehicle under traction/braking (slides)
      • Let's first discuss braking a single wheel / tire
      • Reference to braking a two-axle vehicle
    • Discuss the 6 cases of locked wheels during braking without steering
      • Is it possible to evaluate stability for these cases with bicycle model?
      • This may be first course project - run simulations; animate the 6 cases (actually 7)
    • The locked wheel cases motivate looking at ways to regulate slip, and need for feedback control

Week 5 -
  • Lecture 9 (Tu, 2/16) | 
    • no class meeting held today; you should be working toward HW2 and Project #1
  • Lecture 10 (Th, 2/18) | 
    • Review an approach for completing HW 2; rubric; one solution; simulation code
    • Two matlab files that may help with HW 2 and Project 1.  Lots of gaps, but there are parameters, initial conditions, etc., that I have used  in past.  It is offered as is for you to use as you will.
    • Control Concepts - 1 (slides) - quick preview of topics

Week 6 -
  • Lecture 11 (Tu, 2/23) | 
    • Control Concepts - 1 (slides) - cont.
    • HW #2 due next time; Project 1 due by 3/3
  • Lecture 12 (Th, 2/25) | 

Week 7
  • Lecture 13 (Tu, 3/1) 
    • Open questions on Project #1 - due on Thursday
    • Oops.  still have not posted slides, but you're all working on Project #1
  • Lecture 14 (Tu, 3/3)
    • Spent more time on project #1 discussion
    • Project #1 is due today | extended to Monday

Week 8 -

Week 9 - Spring Break (March 14-18)


Week 10 -

Week 11 - 
  • Lecture 19 (Tu, 3/29) | 
    • Show some more examples on closing loop - linear cases
    • Continue with Code examples for implementing PID for HW #3
    • Slides from today
  • Lecture 20 (Th, 3/31) - 

Week 12 - 
  • Lecture 22 (Th, 4/7)
    • Vertical dynamics and ride - 1 | today's slides
      • Quarter-car vibration/ride models
      • Time-domain response of simple, base-excited mass-spring-damper
      • 1/2-car model
      • Frequency response from transfer functions (for insight into vehicle vibration response)
      • Terrain descriptions for vehicle vibration analysis
      • Supplemental reading: Random vibrations


Week 13 - 
Week 14 - 
Week 15 - 
  • Lecture 27 (Tu, 4/26) | 
    • HW #4 due today
    • How will we finish the semester? 
      • Rollover, extended vehicle handling with suspension and roll
      • Two-wheeled bicycle dynamics and control
    • Ford presentation
  • Lecture 28 (Th, 4/28)
    • Vehicle rollover dynamics and control | description of 6 problems
    • HW #5 - work problems as given in the slides provided above.  Must submit solutions to problems 1 and 6 +select either of 2, 3, or 5.  Submit 3 problems total. - due date is 5/6/16
      • NOTE: Must show fully rationalized solutions from basic N-E equations - not the short-cut solutions as provided in the slides.  I will be looking for well defined coordinate frames, vector definitions, etc.
      • a little more help on problem 1 - part (b)

Week 16 - 
  • Lecture 29 (Tu, 5/3)
  • Lecture 30 (Th, 5/5) 
    • Submit your plans for Project 2 (which is due 5/13/16)
    • Course review - last meeting day
