Not that I shouldn't be working on the race car, but I do mess around with some suspension mods using ACAD. Does anyone have any blocks of rearends, trailing arms, roll cages, stuff like that? Would be interesting to see what other's do.

Thanks.

I am currently drawing up a car we will be building for 2005. I am doing it in 2d right now but might try 3d later. I plan to do FEA on the chassis as well. I have drawn a rim, 62 and 60 inch nine inch floater, five star body and a few other things. I hope to build the entire car on autocad before we cut a piece of steel.
I can send you a few things. send me your email

A mechanical engineer I'm not, so I haven't done anything close to FEA. A fabricator I am, so I just use my experience for that type of thing! But, I have done quite a bit with ACAD, so that's why I use it. I do have suspension software, but it's just easier to make the changes in ACAD and see what happens. I'm interested in any of your drawings, I have just been using lines that simulate mounting/pivot points. I actually use McMaster Carr for a lot of fastener drawings. They have ACAD files you can download that work great. Please email me anything you like and I'll find some of my other things and return them to you.

Thanks,
Randy

dan,
there are a number of very useful suspension programs out there you just need to get one you can relate to. hardest part is measuring your race car. I use susprog 3d.
its not hard to find the website if you do a search.

Njantz - I have mechanical desktop on my work computer and can use the solid modeling part (but I am nowhere near being an expert). The FEA part I have only played with. I plan to learn this in the future.

I found a 3d fea structure design program on the net (I will find the site and post it tomorrow). It seems to be very good at doing truss type structures. My plan is to do a 3d analysis on the frame and cage structure to maximize stiffness and minimize weight. As well, apply very high point loads to the main cage area to see if I can find the weak spots here and hopefully design a safer car as I am the driver too!

I'd be interested in your suspension drawings too (future projects!))

Ratracer - I am just working on a 2d drawing of a camaro clip for my project. Once done I will have a few views of it. Would this help?

I would just like to have some kind of software that I can use to draw (outline scale) different type dirt track division cars (Late Model, Open Wheel Modified, & Street Stock).

I need these outlines to veiw and decide on which paint scheme I would choose. It needs to be something that would allow fonts, color, & graphics to different aspects of the body (quarter panels, roof, front & rear, etc..).

As for my natural drawing ability, it is ZERO. I have trouble drawing a complete circle using free-hand, and making the ends meet...LOL!

Any help would be greatly appreciated

Have a great day everyone,
Wind Walker

The grapes sofetware is the one I was trying. The shareware is at
http://www.grapesoftware.mb.ca/

So far I have only done the 2d tutorial, but it looks good.

you do not need thes high end produts to design paint scheems your looking for art programs such as PSP( paint shop pro) coral draw heck even ms paint the simpel paint program that is on most window machens works you can get demo 30 day demos on there websites if you do a search i bet you can find them

OK, I just couldn't help but to download the free demo of working model. Ratracer, do you have the demo or the real stuff? Looks like it would be a good program, but not for $2500. **** , I paid less than that for my roller!

Maybe it's just the demo, but I couldn't get the right X movement to really work my rear suspension. I'm working on plotting out the movement right now. I just have to do a little "cheating" in ACAD before I import it. Maybe there's a different way.

Thanks Modracer09 & everyone else for the responses concerning the drawing program. It's been a while since I've looked, but I used to own some products such as corel draw, paint pro, and I also have a program from Aol called "Powersuite" (whatever that thing is all about). I have had computers & Aol for many years (12-15), but usually just spend time online reading what others have accomplished within the internet, and not learning how to do any of it myself (such as creating a web page, which I still cannot achieve...LOL).

What I am looking for though, is more to the point of an "outline scale" of different divisions of dirt track cars, that I can fill in the colors & fonts in an effort to get a general idea on what the car would look like on that particular division.

I currently run a Hobby Stock, but I am thinking of moving up to either Open Wheel Modified, or Late Model, and would like to paint the car (from a drawing) before trying it out several times with the real one.

I have tried to paint the idea's on a blank page (Print Shop Deluxe), but it never quite comes out the way I need to decide which looks better with what.

Anyway, thanks again, and have a great day.

Ratracer- does solid works do any motion type things? Where you could model front suspension stuff.

Anybody got a metric frame in autocad I could get, or know where to get one? I'm just trying to play around with it a little.

Thanks

There is an automation add on for this program, but I donít have it. However you can move the suspension in steps 5 degrees, 1 inch, what ever you like and then take all the measurements you want in that position. Then repeat this for as many positions as desired.

Hereís where Iím at on my chassis. It still needs more bracing, but itís getting closer.

hey ratracer how hard is solidworks to use? compaired to autocad?
also on your chassis, you might want a longer pull bar to react slower, also look into adding a brace behind the rear from the main frame to the underslung, also you will want to eithere notch(or curve) the underslung on the lr to get more clearence, or make it removable for dryslick tracks.
what stub is that supposed to be?

Zeroracing, thanks for the advice I will take any I can get. I build this chassis fairly close to some rough plans out of a book I have. Now that I have the basics there I can start making changes to it to get it to where I want it. Yea, I intend on doing the pull bar different once I get the bracing in. The one there is basically just there to hold the rear end in place for now. The stub is supposed to be a Camaro. It is basically a crude outline, but hopefully the lower suspension points are close, the uppers have been moved. A fabbed tube stub would be a lot easier to draw, but I donít have dims for that either.

Solid Works is basically like Mechanical Desktop, if you are familiar with that. It is just different then Auto CAD in the way you create your models. Once you get used to it thought it is faster to create pieces, especially complex ones, then trying to draw all the views you need. Once you have a model made all you need to do to make drawings is select the part, or assembly and which views you want and the program makes the drawing. The even nicer part about it is that they are all linked, so if you make a change in the model the drawing automatically changes and vice versa.

also on your chassis, add some more bracing around were the lr trailing arm mounts. i had mine break last season under my seat. it came just a few inches of going threw my back. now may car is like a tank in that corner also i added a piece of flat steel to make a broken trailing arm deflect away from the seat.
