Llama Posted June 15, 2012 Share Posted June 15, 2012 MATLAB. KILL IT WITH FIRE. AIIIEEEEAAAAAAAAAAAAAAAAAAAEIFAJEFIAEFJAOEIFJAEF. You voluntarily code in that...? I don't know what to say. Aside from that I hate matlab I am envious of your CAD model though, I never had the patience/I'm not redesigning my car Quote Link to comment Share on other sites More sharing options...
mattj Posted June 15, 2012 Share Posted June 15, 2012 Looks good mate, are you looking to ditch the struts and go for a wishbone setup? I was thinking about doing something like that at one stage. I will be most interested in seeing how you get on. if you do you should keed the whole setup nice and low then ditch the zetec and go for a v8, that would be sweet.....

anglia4 Posted June 16, 2012 Author Share Posted June 16, 2012 Matlab is all I know! I started modelling it like that cos I did an FEA course at uni and we learnt how to do simple beam and bar element models using matlab. I wondered if I could use bar elements and clever boundary conditions to model the movement and hey presto it worked. Was easy for doing a bump travel analysis, but then I decided to extend it to model how the chassis would roll about its roll center, taking into account the fact that the roll center moves. This is where it gets complicated, it initiates with a bar element model and calculates the static roll center, then uses that to generate a beam element model (you can add rotational boundary conditions to a beam element but not a bar) of the chassis only, rotates it around the roll center, uses the new outputs of the beam model as the inputs for the bar model, calculates where the roll center is now, and starts the process again. The program is almost 1000 lines long The above post most likely makes no sense to the general population/engineers are superior beings. Yeah didtching the struts and going for double wishbone. A v8 would be very fun, I actually have the beginnings of a chassis model for a trans-am spec anglia on my computer since I have a spare shell and all but nah not going to bother with that now. The aim for this car is handling over power, having a big heavy v8 balanced over the front of my 700kg anglia would not be very helpful for that. I'm looking forward to seeing what I can wring out of my supercharged zetec though. Felixx, the struts are already in the parts for sale section!

I'm keen for a squiz, PM it to me We did ODEs with numerical methods and laplace transforms in MATLAB earlier this year, but I generally use python for all high level programming now.

anglia4 Posted June 16, 2012 Author Share Posted June 16, 2012 Can't remember how well commented it is, its on my other computer but I'll send it to you some time. no sharing though! (intellectual property and all) Quote Link to comment Share on other sites More sharing options...
Benno Posted December 5, 2012 Share Posted December 5, 2012 Awesome project man! I too would be interested in having a look at the code if thats all good. Just interested in seeing how you did it, not going to go round distributing it. Everyone seems to love to hate matlab, but once you get used to it its actually not that bad I reckon. Seems to be the standard for engineering simulations etc anyway, so worth getting used to. Quote Link to comment Share on other sites More sharing options...
eke_zetec_RWD Posted December 5, 2012 Share Posted December 5, 2012 What hubs are you going to use man? Quote Link to comment Share on other sites More sharing options...
anglia4 Posted December 6, 2012 Author Share Posted December 6, 2012 I haven't run that code for a while, I think it still has a few bugs. I might send it out some time if I ever get it finished, its bloody hard to follow unless you understand finite element methods, and even then I suck at code so its hard as to follow. At this stage I'm planning on using late cortina hubs. I was going to use MX5 but couldn't get the geometry to work with a few packaging problems. Then I was going to scratch build some, worked out the geometry I wanted/could get, and it turned out bloody similar to the cortina ones. So thats what I'll use in the current iteration of the plan.

eke_zetec_RWD Posted December 7, 2012 Share Posted December 7, 2012 Iv got cad designed frnt for cortina hubs. But the steering rack would be too high to sit the moter on I'd say. Could get a way short rack and put it underneath though Quote Link to comment Share on other sites More sharing options...
Guest 77magnum13hundy Posted March 13, 2013 Share Posted March 13, 2013 Thats quite a bit of panel work there, but once its done its done. This thing will go mental if you s-charge it as well as it being a dohc 2litre. Keep up the good work. Quote Link to comment Share on other sites More sharing options...

BDA780 Posted May 3, 2013 Share Posted May 3, 2013 Wow this is a damn sweet project! Should have read this before Nats and talk to you there. Well impressed by the Matlab model. Potentially a business venture for race cars?? Keep it up man. Quote Link to comment Share on other sites More sharing options...
anglia4 Posted May 3, 2013 Author Share Posted May 3, 2013 Haha cheers man! Its been a while since I've worked on it so I don't think it got mentioned once at nats! One day I would like to design and build race cars for a living, but I have a lot of learning to do yet on my own projects before I could do that. Dad and I have just finished building a race car from a 95 mustang. I've read a few suspension tuning books so I've got a good grip on the theories, but i've found it really all comes together once you start driving it (and I've only raced it once so still alot of learning to go!) Its not until you have a drive and feel what the car is doing, make some changes and see the improvements in feel and lap times, thats when you start to do the real learning. As I said, I've only driven it once and I've already got big ideas for the next round of improvements! 1 Quote Link to comment Share on other sites More sharing options...
Jorden Posted February 4, 2014 Share Posted February 4, 2014 Hey mate do you know what the blue and white seats you put in are called/where i would be able to buy them from? They look awesome in the car and fit really well. Cheers. Quote Link to comment Share on other sites More sharing options...
anglia4 Posted March 16, 2014 Author Share Posted March 16, 2014 Its been so bloody long since I've worked on this thing I really don't know where to start anymore. There is still alot of panel work to do, lots that I want to do again as well. But I'm pretty over that so I might start on some of the custom fab soon. I've finished my pedal box design so I'll get my cert man to look over it and then might start building that. Its just a good little sub project that I could knock out and make me feel better about the rest of the project Quote Link to comment Share on other sites More sharing options...
Rookie Posted March 16, 2014 Share Posted March 16, 2014 That is the way to keep up motivation. This will be a sweet little car when it is done. 1 Quote Link to comment Share on other sites More sharing options...
