![]() My approach is, to use pictures of a car to sort of estimate locations of outer joints (like, +/-2cm) and from there, try to move around outer points to see, in which direction you need to go with them sideways and upwards, to get closer to the curves. Having a proper suspension analysis program will help a lot. I feel like there's a formula here that will help me and I'm just not seeing kind of 'been there' already. It also doesn't help that when I try to find calculations for finding side-view instant center, they all require me to already know my mount points, which is what I'm trying to find in the first place. I guess side-view instant center is what I'm sort of trying to find in the first place, so this formula doesn't help either. This doesn't really help as I already have all of these valuesĪnti-dive % = (Side view instant center height)/(height of 100% anti-dive line at instant center distance behind the front axle) I've seen two formulas:Īnti-dive % = Brake Bias Is there any way I can use all of this information along with the coordinates I have to map out the suspension geometry in relation to the car?Ĭan you explain how I can use the Anti %'s to find the inner pickup points? I have a pretty good idea of how to map out everything in AutoCAD, I'm just not sure how to factor in anti-dive and anti-squat.ĮDIT: I've been reading a lot about anti-dive and I'm still a bit lost on how to use it to locate my chassis mount points. If they are, I also have dimensions for various springs for this car. I'm not sure if these are meant to be motion ratios (they are numbers less than one, I can't say what number exactly for confidentiality reasons). I also have one value each for front and rear called "Ratio (Wheel/Spring)". Roll Center change per suspension movement So I know where the chassis side points of the suspension are in relation to each other, but not where they are exactly on the car. I also do not have coordinates for the upper and lower wishbone mounts and steering arm mount on the wheel upright, nor do I have dimensions or angles for the wishbones. ![]() how far forward of the midpoint of the wheelbase, how far left or right of chassis centerline this point is, and how high this point is. The problem is I do not have any measurements that show me where this reference point is on the chassis i.e. I have a page that shows the Cartesian coordinates of the chassis-side mounting points for the damper, upper and lower wishbones, and steering arm, all in relation to a reference point on the chassis. I have quite a few bits of real world data for this car (I won't say which just yet), but I'm missing some very key data points that would help me plot a suspension (I'm using the ISI physics sheet). I'm trying to map out the suspension geometry for a car. I've got a very strange situation that I need some help with. ![]()
