1.Given a 2012 Honda Civic DX Coupe, what would the damping coefficient be for the given mass and spring rate, if a free vibration front end deflection of 75mm (about 3 inches) just returns the vehicle to the neutral position. Using the spreadsheet given earlier, recalculate for the same deflection in the rear end. What are the equivalent loads of these deflections?
2.Based on the Pneumatic Tire book, starting on page 776, discuss factors governing rolling resistance of tires. Propose a simple means to measure rolling resistance at a given speed. (1/2 page max)
3.The NHTSA and EPA collaborate on CAFÉ standards. Go through the Final Green House Gas and Fuel Efficiency Standards listed and evaluate what is being done, how, and conclusions. There are 2 embedded links in the paper that you should look at.
4.The EPA Federal Test Procedure (FTP) below uses several phases of vehicle simulated operation. Discuss these and how the emissions are actually measured (bagged weights of pollutants) on chassis dynamometer. How does this represent actual driving conditions, and (in light of the recent problems of some manufacturers) how has EPA revised procedures to ensure better compliance? How are the fines that VW paid just in the US, due to the Diesel issues, expected to be allocated.
