How can I test a new sas I came up with?

[jake1994]

So I have been looking at 4 links 3 links radius arm and all that set up. So one day I was thinking of how to design a long arm set up with no binds and try to keep it solid and functional (binds, travel, flex, shakes, and other.

Is there a program that I can draw and see if it works?

Can I do a small scale? I'm trying to build a small one for my lawn mower before I do a full build on my truck.

Any help be good thx.

Look up 'Extreme 4x4' TV show, somewhere they offer a lot of technical info on 4 links.

Well it's not really a 4 link... I designed it and I haven't came across one that looks like it. It's kind of like a radius arm but the arms and links are centered 69 the arms. So on the top of the axle cemetrically mout 2 links wide as you can then to the cross member and then on the cross member 2 links wide but offset lower so it's not hitting then to the lower center of the axle. Let the drive line float between it..

I use a program called solidworks. It's a cad program for engineers. You can design and test just about anything.you can set your constraints to contact and see exactly were things hit during movement. You would have to find some one local to you as its not free and pretty pricey. But there are users with the program always looking for side work. As for building a scale or prototype to test try using PVC pipe. It's very cheap, you can thread it or use threaded couplings.you will have to buy your links but you'll need those anyways. But it's a lot cheaper and easier to work with instead of scrapping expensive steel tube until you come up with the right setup. Obviously it won't support the weight of your truck ,so with your truck on stands you can manipulate your axle by hand/jack. I use a combo of computer program and hands on for all my projects.the computer helps visualize a concept without spending money on material. Actually I think there is a program that is not too pricey and available to anyone. It's called bend tech pro.
Your lawn mower has solid axles??? You must have some serious grass.lol
