Below is data for a 1994 Saturn SL2 equipped with a 1.9L DOHC engine. Engine WOT Data: 500 N (rpm) bmep 743 (kPa) 1000 1500 2000 2500 3000 3500 4000 4500 5000 5500 6000 887 970 1047 1094 1073 1052 1058 1094 1089 1063 1001 Transmission Data: 1st 3.250 Chassis Data: 2nd 3rd 2.055 1.423 4th 1.032 5th Final 0.730 4.060 Traction Limits CGht=30-in Whlbase 102-in WgtDistFront 55% . Vehicle Width: 52.5 in Mpeak = 0.8 Atm Cond: P1 atm Tair=294-K Coefficient of Drag: 0.345 Vehicle Height: 67.6 in (1.717 m) (1.333 m) Test Weight*: 2405 lbf (1091 kgf) *Assume this includes Driver Tire Data: Tire type: P195/60R15 (use Table 4.2 for rolling radius) Coefficient of Rolling Resistance: 0.010 Driveline efficiency: Use Gillespe's rule of thumb. Effective mass: Use Gillespe's rule of thumb. Shift strategy: Use the simplest shift strategy, i.e. up shift whenever the engine red line is reached. Add (0.3 sec)x(number of shifts) to your 0-60 mph time to account for shift delays. For extra credit you can try improve the acceleration performance by trying alternate shift strategies. Integration time step: Use a time step of 0.1 sec (or less) Assignment: Perform the following items first assuming power-limited acceleration, then assuming traction limited acceleration with perfect traction control: 1. Determine the 0-60 mph (0-96.6 kph) acceleration time for this vehicle. 2. Determine the maximum speed and distance travelled at 20 seconds. (These values do not include the shift delay) 3. In your short report include plots of acceleration vs. time, speed vs. time, and position vs. time. State clearly the maximum speed obtained and the distance traveled at 20 seconds. Do this for both acceleration models on the same plot. (i.e. 2 traces) 4. Show sample calculations for 0 sec. Including unit cancellation.
