Quote from: bsauder189 on November 05, 2017, 06:59:24 PMHere's what I think we need as far as being able to adequately simulate a dirt latemodel, or any 4 link style suspension.Pardon my terminology when it comes to trying to discuss what we need.-Axle needs to "wrap" either by making a lift arm/pull rod style addition to the physics. Here is a picture to show what I'm talking about. https://www.google.com/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact=8&ved=0ahUKEwjp8-D7iqjXAhWr44MKHfHBBZgQjRwIBw&url=http%3A%2F%2Fwww.hotrod.com%2Farticles%2Fctrp-0612-race-car-forward-bite%2F&psig=AOvVaw3npC0SRRIwG6OaN4y8L10Q&ust=1509993680330655-We need to be able to adjust the j-bar/panhard bar. This is done quite a bit when at different tracks or with different track conditions. Pictures to show what it is and an animation video to show how it works. https://www.google.com/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact=8&ved=0ahUKEwixwsi5i6jXAhUq74MKHQKlDq4QjRwIBw&url=http%3A%2F%2Fwww.hotrod.com%2Farticles%2Ftaking-closer-look-bulldogs-eight-inch-quick-change-rear-end%2F&psig=AOvVaw25EMVvEkzcMeOtQMyU4B0G&ust=1509993801433826 https://www.youtube.com/watch?v=rjFTaQXarWc With this animation, picture the plate on the bottom being attached to the rearend. The higher it is on the left side of the frame (with the same length overall) the more it moves the rearend to the left. And vice versa. -We need to be able to simulate the 4 bars that connect the rearend to the frame. What I mean by that is we need to be able to put more angle in the bars to achieve more axle lead under acceleration/load. http://img.photobucket.com/albums/v424/NJantz/TimmyMcCreadie.jpg The angles of the bars determines your timing of the birdcage (what they attach to on the rearend). I've tried to find a video of a simulation of angle, this is the best I can find. https://youtu.be/JMjWw_adWQI Here is a video though of how the suspension works as a whole.https://youtu.be/i57DnUY1EHg?t=10I don't think that as far as the front end settings go, we need anything special other than the ability to use bump stops on the RF and LF. Actually bump stop options should be avaliable on all 4 corners.Aside from getting super technical when it comes to what guys are doing today with LR springs and stacking them, I think the stuff listed above would get us in the ballpark for being able to produce something that a lot of people would gain interest in.
