I am learning to use a new to me software development suite (Qt SDK) and thought of a useful project to get my feet wet. I am designing a driveline simulation tool. The user inputs various parameters, like tire size, rear end ratio, RPMs, etc. The program then plots the RPM vs MPH. I know that these are available on the web and there are super nice ones available for purchase. But, it will be a way to familiarize myself with the development software and should be fun at the same time. And you all can have input into its layout and functionality! Attached is a snap shot of the current GUI. The large white pane on the right will display a dynamic graph that updates with each parameter change. The user would will also be able to save configurations and compare them with graph overlays. I thought it would be a neat way to learn the SDK and also serve as a community tool.
Sounds like a very nice, useful project. I have an idea or two that shouldn't be too hard to implement and might help your tool stand apart from the rest... First of all I see you have a drop-down for predefined gear ratios, so you may already have this in mind; having the program contain data about common transmissions. But another good idea I think, would be to include a formula for recommending the proper speedometer gears for your drivetrain and tire size. I've never seen that feature before in a calculator such as this, and I think it would be an awesome addition. Hate trying to figure that out on my own. It's neat that you're using QT too... Going to try and keep it cross-platform?
Thanks for the input. Yes, the transmission gear ratios would be pre-loadable, and then tweaked if the user wants. Cool idea about the speedo gear, I can add that to the list. Yep, using QT. I have used it before, but not in a complete development suite. The suite compiles, cleans and keep the project organized. Can add headers automatically, that kinda stuff. And yes, the program will be cross-platform, the SDK can pre-compile for Windows conversion.... I think. lol
Well please keep the thread updated as you work on it, I'd love to see this take shape, as well as make use of the tool myself. There's all sorts of "car math" I do occasionally that I'd really rather leave in the capable hands of a computer. And to me, being both a car geek and a computer geek (a Linux geek in particular) this is a "build thread" that will likely hold my interest every bit as much as if you were custom plumbing a turbo. And, (do I even need to say it?) you have most definitely got yourself a beta tester right here when the time comes!
Great idea. Where can we put it on the forum so its easy to find? Lots of questions about gear ratios especially from newer members. Be nice to find a quick link for them.
I'm sure we can figure something out about where to place it once it can be used. Either a down loadable link, or a web based program. The gear ratio questions are what actually spawned the idea.
