I usually do some calculations to check that the castor trail does not go negative in hard braking, with the vehicle pitching. For this you will need the initial castor, the bump castor slope, and the actual vehicle pitch angle.

You worked on it? I think its a neatly done suspension and its got excellent media reviews! I wonder though...Have you engineered the structure of the mounting plate on the trailing arm for certain compliant toe characteristics? Any chance of this going on any utility / SU- vehicle in near...

Does anyone know of a site/image having good info on the control blade type of suspension (ford territory/focus vehicles)? Best Regards, NS

Does anyone have some data regarding the typical driving habits of people for: 1. lateral acceleration 2. steering angle (at the road wheel) 3. vehicle speed 4. and how do the above change with geographical area, type of vehicle? This data would be good in deciding upto what limit a math...

You may find some good info. in Theory of Ground Vehicles by Wong.

Hello All, Any info on the use of a longitudinal watt's linkage w/ a panhard rod? I found a 80s vehicle using this type of a rear suspsnion on a FWD alfasud.alfisti.net/asch.html Any new ones? Regards, NS

Its the BMW 528. Driven it?

Greg, I was looking at some published results for some Peugeot & BMW models which claim a longitudinal stiffness value of 10 to 15 mm/kN. This translates to a stiffness of 100N/mm to 67N/mm. I would assume the unsprung corner mass to be say..40-50 kg. that leads to a freq. of around 6.8 Hz...

Currently I was targeting a low camber compensation of 30~35% for Pickup Truck. For higher ratios, during double wheel bumps, the tires would scrub outwards on the inner edge. I'm still not sure how to strike a balance ebtween tire wear on straight aheads and cornering with heave roll (have a...

Is there a method for setting camber compensation? I suppose one it would be a strong function of the vehicle roll gradient (and the time distribution the car spends in corners or on straight aheads, although this would be quite area dependent). I'm not sure how to set a target value though. Any...

is it possible to use some dummy (random) phase data then?

Hello All! I am a newbie at MATLAB. If i plot the FFT of a signal such as Asin(2pi*w1*t)+Bsin(2pi*w2*t), the magnitudes are not scaled correctly. Any idea about this? Also, I have a PSD plot for a surface irregularity. I need to reconstruct the original time history from this plot. Can...

hello all! im working on a truck tire [12R22.5 radius of 520mm and a width of 350mm]. would any forum members have any guesstimates on typical vertical stiffness and damping values for this tyre? also i would like to estimate some values for longitudinal / lateral coefficients. any empirical...
