After closely inspecting the front spindles of a new '05 Ford Mustang (strut suspension) I notice that the hub centerline lies forward of the lower ball joint by about 25mm. I was hoping to spark some dialog about what effect this geometry has in terms of handling and steering feel. Perhaps...
Would anyone know of a good resource for getting dimensions and purchasing OEM type axle flange nuts such as those used for FWD and rear IRS applications? I'm looking for a relatively large flange diameter (52-55mm), something compatible with a 42mm inner diameter wheel bearing. Preferable the...
All,
I'm looking for information about how many MRI are sold annual in either the US or Europe. What would be even more useful is a breakdown by OEM e.g. Siemens, GE, Toshiba, etc. If anyone can provide this information with reasonable confidence it would really help me out significantly...
All,
Maybe this is a bug, or I could just be doing something wrong, but when I ask SW2005 to display a chamfer dimension in the, for example, 1X45deg format it does not do it. It typically displays the size and the angle as two seperate dimensions which is quite annoying. Any solution will be...
Hi all,
What is consider the minimum required steering angle (at the wheels) for a street driven vehicle in order to have a reasonable turning radius? This will be a function of the wheelbase, so if anyone has a handy formula available as well as any comment it would be greatly appreciated...
At a recent ALMS race I had the opportunity to see the front suspension of the C5R Corvette and the Lambo Murcielago R-GT. Both use CNC machined aluminum upright that seem to also house hub bearings. The carbon brake rotors were very close to the outboard face of the uprights in both cases so...
Has anyone had experience designing a front suspension that provides a significant amount of roller camber compensation? Would anyone care to comment on why designing a suspension with a lot of positive caster and mechanical trail will give superior performance during cornering and turn-in...
Would anyone care to share what they know about loading of automotive hubs for front suspension applications? I am interested in knowing if anyone has done testing during racing condition to see what sort of load spikes can be expected when a driver decides to drive over the berms during corner...
Coming from the ProE world, I was hoping SW had the capability to create mathematical relationship between dimensions. ProE sets up a unique dimension tag number that can be inserted into equations relation dimensions. This tag number can even be used to drive dimensions in other parts or...
When in sketcher and adding dimensions, SW seems to only allow dimensioning and adding relationships from edges instead of allowing you to choose an entire surface. This causes errors and can cause the model to fail when the edge is eliminated (i.e. adding a round or chamfer). Am I just a SW...
Does anyone have any suggestions on how to deal with components that are bolted together in Cosmos Works? Assuming I want to analyze an assembly and included the fasteners, what sort of contact definitions are most appropriate? The problem I have is that one of the part in my assembly acts as...
The Corvette C4 uprights are made of forged aluminum and will package inside of a 17" wheel to minimize scrub radius. They also have the benefit of using a sealed hub assembly that bolts in. I am thinking of using them on a future race car suspension. This is obviously not a novel idea...
Does anyone have access to tire performance curves from any of the major manufactures? I am looking for curves for BFGoodrich g-Force T/A KD tires in the 255/40/17, 275/40/17, and 315/40/17 sizes. Even if you have info on other manufacture' tires in these sizes please post them. Thanks in...
It is commonly know that for a SLA front suspension, in order to minimize bump steer, the inner steering rack joint should fall in a plane determined by inner upper and lower control arm pivot point. Additionally, the outer steering ball joint that connects to upright must also lie in a plane...

From observation, it seems that for a particular style of vehicle group (i.e. front-engine rear-drive sedan, rear engine sports car, etc.) there are suspension characteristics that have been proven to work very well. My question is: For a front-engine rear-drive sedan with a SLA front...
Has anyone had experience with rear suspension systems that use a torque arm to control axle rotation? I plan to use one on my vehicle which as a wheelbase of 108" and a weight distribution of about 55/45 front to rear. My thoughts are that I will make the t-arm so that it extends very...
During the course of the last few months I have been designing a rear suspension system employing a solid rear axle, 3-link torque-arm suspension, and a centered watts link. The watts link has an adjustable pivot height for various roll center locations. The suspension will be sprung with...
