Classification of Road Profiles on the basis of Degree of Roughness by using Displacement PSD Approach

 Some Fundamental Observations related to vehicle dynamics:   1, What are the two types of tierod errors with respect to ride steer? And what is the effect of these errors on the toe curve? 2, If we have toe out in rebound (due to bump steer) in the rear suspension, is this an understeer effect or an oversteer…

Please note: Front Ride Rate: 200 lb/in Rear Ride Rate: 250 lb/in   1,Calculate the following parameters: (i) Roll moment (ft-lb/g) (ii) Roll gradient (deg/g) (iii) Load transfer due to roll or elastic component (lb/g) (iv) Front roll stiffness (ft-lb/deg) at wheel center level (hint: isolate the tire contribution)…

AIM: 1a, These questions test conceptual knowledge. Answer in a sentence or two in your own words. A textbook definition is not necessary Calculate the tire stiffness. Tire size – 275/40R18, Free radius is 13.33 inches and loaded radius is 12.36 inches Explain in your own words what slip ratio and slip angle are…

Problem set 2a- combines slip This challenge tests your understanding of combined slip brush tire modelThis exercise should be done in octave. Turn in your code • Write an Octave script to show the effect of slip angles (2 through 10 deg in increments of 2) on the Fx vs Fy relationship.• Use a slip ratio range…

AIM: Write an Octave script to show: • How different slip angles (0 deg, 2 deg, 4 deg and 6 deg) influence the force (Fx and Fy) vs slip ratio relationship (sweep from 0 to 60%). • How different slip ratios (0%, 3%, 6% and 9%) influence the force (Fx and Fy) vs slip angle relationship (sweep from 0 to 20 deg).…

ASSIGNMENTS: 1. What is the difference between deterministic and stochastic models/methods? Which one would you use to study road profiles 2. Explain Fourier transform in your own words 3. Explain PSD in your own words 4. What are the three main aspects of suspension performance evaluation that we discussed 5. How many…

AIM: Using the PSD data given, determine the road quality using the ISO classification ISO 8608.These are your deliverables:  Download the PSD data from here:  https://drive.google.com/file/d/0B2S2ZJKcURAmeDNFRlMtMm5MSTQ/view 1. Plot showing ISO classification for roads A through H (Use higher end of range for…

Hi, Everyone recently I have completed this project which is related to Vehicle Dynamics.  This Project include Longitudinal Load Transfer, its effects over vehicle stability, and how we can play with Anti-Charactersticks to turn LLT in our favour during Suspension Geomtry Modelling. Calculation of Longitudinal Load…

   This challenge tests your understanding of front and side view kingpin geometry. Also draw a rough sketch using the hardpoints to visualize the suspension                                   Assume the ground to be at zero…
