Dear developers, because of mas2.exe file does not open rFactor2\Installed\vehicle\MR01_car\1.42\MR01_car.mas to configure Marusya through Motec I need the data. From the file HDV, tbc, engine.ini need: LifetimeOilTemp=? OptimumOilTemp=? Front3rdBumpStage2= ReboundTravel=? front & rear CGHeight=? Front3rdBumpTravel=? Front3rdReboundTravel=? Rear3rdBumpTravel=? Rear3rdReboundTravel=? BumpTravel=? ReboundTravel=? BumpStage2=? ReboundStage2=? BrakeResponse=? Temperatures=? OptimumPressure=?
From the data that you are asking I can imagine that your project is very detailed. Can you share it?
only if u can read those data in motec and understand what does they mean)) if not it (project) doent help u. but u can make your own all channels u can find in right column in motec)))
To calculate the springs don't need a huge project, you need to get the load on the tire and split the data from the HDV
LifetimeEngineRPM=(16700,570) LifetimeOilTemp=(115.3,5.9) Front3rdBumpStage2=0.082 Front3rdReboundStage2=-0.087 Rear3rdBumpStage2=0.075 Rear3rdReboundStage2=-0.085 ReboundTravel=-0.05 ReboundTravel=-0.089 CGHeight= Approx 22cm BumpTravel=0 F Front3rdBumpTravel=0 Front3rdReboundTravel=-0.052 BumpStage2=0.082 ReboundStage2=-0.087 R Rear3rdBumpTravel=0 Rear3rdReboundTravel=-0.088 BumpStage2=0.075 ReboundStage2=-0.085 BrakeResponseCurve=(-35,411,688,1590) No such things as Temperatures=? Approximation might be 80-105°C OptimumPressure=? Sent from a mobile device using Tapatalk
OptimumPressure - These data from another file on tires. For example for FR35 this TIRES_MICHELIN_2010_RST3.5.TBC For FR35, "compound" rear tires, OptimumPressure=(98, 0.0108) To calculate the correct pressure rear tires, take the average load on the tire, multiplied by 0.0108 and add 98. For Marussia is about - Tire_pirelli_s.tbc etc...
Hi, Tim. Have a couple of questions about Marussia and fr3.5 telemetry data. Marussia; 1 ) u gave us Front - BumpStage2=0.082 ReboundStage2=-0.087 this mean that 82 ms/s Speed where damper bump moves from slow to fast and 87 mm\s Speed where damper rebound moves from slow to fast so is this correct? whats happening in this difference of 5 mm/s (for rear this is 10 mm/s difference). 2) as u said ReboundTravel=-0.05 (as i understand for front) and ReboundTravel=-0.089 (for rear) so this mean - prevents rebound travel (for example, when upside-down), ??? mm max front ride height plus ??? mm leeway is this correct if i use 50 mm for front and 89 mm for rear - Prevents rebound travel (for example, when upside-down), 50mm max front ride (89 rear) height plus ??? mm leeway . or there should be used another numbers in mm ride high (not 50mm and 89 mm) - prevents rebound travel (for example, when upside-down), ??? mm max front/rear ride height plus ??? cause as i know rebound travel its ride high+leeway, so 50 mm - its ?? ride high + ?? leeway so what the number in mm of the (front/rear) leeway? or and what do u mean by BumpTravel=0 - u mean there is no bump stop???? Travel to bumpstop with zero packers and zero ride height - 0??? 3) about FR3.5 - why the suspension (rear) in lb/in (American system) if all other in Si (mm, kg etc.) - why in hdv file fr3.5 - ReboundTravel=-0.08 Prevents rebound travel (for example, when upside-down), 80mm max rear ride height plus 10mm leeway) but in game its only 56 mm ride high for rear (for front the same (only another number). 14mm - difference what about them?
1) The Stage2 speeds are just the knee-point of the damper rates. If you check out some shock dyno you'll see that point doesn't necessarily have to be the same for Bump & Rebound nor Front to Back . It is a product of the valving used in the damper. Figuring out where that point should be is beyond the scope of my knowledge, and some pretty heady stuff. 2/3) I've never felt the comments about the travels were helpful. If it helps, think of it this way: Travels are the distance the wheel is able to move before contacting the bump rubber when the ride height is set to 0. If Bump Travel = 0 then it is sitting on the stop when the tub is on the ground. If you raise the front 50mm, then you'll have 50 mm until the bump rubber is contacted. Rebound works the same way. It is a little weird to have mixed units. If I had to guess, I'd say the MFG data from Eibach they were using specified in lb/in, and so they rolled with it.
in F1 car in damper there is a BumpStop (small detail ("barrel") filled by oil) - the main aim of it to save the entire construction of damper from destruction, but if its equal to 0 so there is no BumpStop (detail "barrel") in damper at all if u get the f1 car from the ground by crane the suspension will go first - this one ___mm max ride height and then ??? mm leeway - together it will be 50 mm for front and 89 for rear (sorry for my English.. try to explain as i can) edit; ReboundTravel=-0.050 // Prevents rebound travel (for example, when upside-down), 44mm max front ride height plus 9mm leeway (FISI2012) (how it 44+9=53 mm, but ReboundTravel=-0.050 is this correct?) will it be correct for Marussia (44mm and 9 mm for front)?what about rear? for example FISI2012 have the same bump\rebound stage2 (BumpStage2=0.030 // Speed where damper bump moves from slow to fast ReboundStage2=-0.030 // Speed where damper rebound moves from slow to fast) so its 30+mm/s speed where damper moves from slow to fast bump/rebound but in marrusia 82 and 87 front in FISI 2012 bumptravel also =0 (0mm), so there is no bumpstop so how it can be that BumpStopSpring=50000 // Initial spring rate of bumpstop BumpStopRisingSpring=8.00e7 // Rising spring rate of bumpstop (multiplied by deflection squared) BumpStopDamper=2400 // Initial damping rate of bumpstop BumpStopRisingDamper=3.20e6 // Rising damper rate of bumpstop (multiplied by deflection squared)
In short, to make it easier to setup we use 'BumpTravel=0', but set the packers to a non-zero level instead. A better description might be travel relative to 0 ground clearance before the bumpstop engages, where a value of -0.01 would mean at 0 clearance the car is already compressing the bumpstop by 1cm. For the Marussia, the minimum packer on the front end is 5mm, this means the bumpstop will engage 5mm off the ground, if your packers are set to 20mm, then it's 20mm from the ground level. And about the FISIR 2012, the description obviously wasn't kept up to date with the parameter changes, sorry for any confusion.
Sorry about steering this further off from the Original Topic. Am I correct that this means @ 5mm clearance (measured ground to chassis), the bumpstop is engaged? OR With the 20mm packer example: The bumpstop is engaged when there is 20mm of clearance? Restated: @ 5mm ride height with 5mm packer, the bumpstop is engaged? Just so it is all in one place: Am I correct to state that for the front, in the rebound direction, @ 0 Clearance, there is 50mm of available movement until the damper hits the internal "rebound stop"? Am I also correct to state that raising the ride height (increases clearance) and transfers some of that rebound distance to bump. Basically, with 5mm of packer you'd have something like this?
