Early 70's suspension analysis

Early 70's suspension analysis

thread800-251968: Steering and suspension analysis
Hi. As you will see from the referenced thread, I first asked yourselves for help with this project some 4 years ago. Finally, the model has been built, and I'm in a position to start drawing some conclusions and have started this thread in the hope you will help me understand what I've discovered.
The model has been built using SolidWorks by an chassis engineer who has many years in designing race applications but who does not comment on road cars, which he considers a separate field of experience. SolidWorks was used rather than his usual programs because of the difficulty in modelling the trunnion part within the front suspension.
My own professional engineering experience is from cryogenics and thermo, cars are just a hobby. I have read a lot of RCVD and the designer is a willing person to help me learn but both he and I felt your own particular familiarity with road car designs and packaging limitations would be invaluable.
I would like to post my findings and ask for your comments and thoughts from my questions.
Thanking you in anticipation, Colin.

RE: Early 70's suspension analysis

any chance that you could post a jpg image of the model?

RE: Early 70's suspension analysis

What vehicle(make, model, year, color and trim level) is your model based on?

Supposedly production Mustangs and Camaros got much improved camber curves in the late 60s or 70s as a result of TransAm competition.

RE: Early 70's suspension analysis

Hi. I've attached a file with a front view, hope it shows the trunnion and front layout clearly. The rear is conventional long-short A arms with bespoke rear upright.
The car is a 1972 M series TVR and the front upright, trunnion and steering arms all same as a Triumph TR6. It uses a rack from a Triumph 2000 of similar era, this was specified as it was a better match than the TR's for bump steer as tested at the time. The suspension arms and all chassis was TVR.
I know the designer of the chassis very well as a friend and he as interested as I to hear what experienced people think of the job with the benefit of 40 years.

RE: Early 70's suspension analysis

Hello Colin,

I, for one, would be very interested in learning what you discover. If you are interested, I would be happy to share some data, as I've collected some suspension set-up information from various people who race, or track their M-series cars.

By the way, would you pass my thanks along to Mr Bigland, for providing me with a car I truly love?

Thanks in advance, and best regards,

RE: Early 70's suspension analysis

Thank you B for your interest. I haven't made much progress as I've once again got side-tracked by life. I do not want to waste the time of those that may wish to help on here by keep vanishing, so have decided to properly collect the questions and time to debate the comments before trying again. I think I have seen you on PHeads so will PM you there and not clog this place with chatter.
