One of the things that has been bugging me about LFS and as a result, VHPA is the values used for the damping rate. From what I have see (at least here in the US) is that dampers are rated at .52m/s or 20in/sec.

It is virtually impossible to get these values converted over to 1m/s. Well, it wouldn't be so bad if the damping rate were linear, but again, in most cases it doesn't seem to be. I only have experience with road going dampers though, so it might not be true for race dampers.

The modern dampers I am familiar with are very progressive similar to a second order differential equation where the rate of damping reduces as the rate of motion increases. The highest rate of change is between 0 and .3m/s. After that, the slope drops off considerably and becomes more linear.

So, if you get a value from a damper manufacturer, say Bilstein, they will give it to you at .52m/s and it will be something like 2000n. You can't really just double it to get the proper m/s value and even if that did match up, it wouldn't work for slower rates, the values would be much too low.

Anyway, I don't know of a way around this.

But it would be nice to either a) allow entry at different rates and then offer an approximation for variable rate dampers. and b) find out exactly what Scawen does to calculate damper values given a single spot value at 1m/s (I think we all assume it is just linear now).

If we knew exactly, then you could put in values that would give you the correct damping at the slower rates (which are the most important) and would probably be a bit high for the faster rates (assuming that Scawen takes that into account, which I am sure he does).
