JVN's Mechanical Design Calculator 2016 by JVN

This new version published for 2016 includes some small improvements.
Quote:
Incorporates the "tested" motor values from motors.vex.com
Includes drop-downs to select motors directly from gearing sheets (or you can still enter your own numbers).
Includes sheets for design of drivetrains using VEXpro and WCP gearboxes (with drop-down selection of gearing options)
Includes a sheet for articulated drives (Butterfly, Octocanum, etc) with different wheel types, and varied gearing between wheels.
Some sheets have been simplified for inexperienced users.
Sheets have been tweaked to make it easier to have "multiple iterations" on the same worksheet.
Older versions still available:
http://www.chiefdelphi.com/media/papers/2755
http://www.chiefdelphi.com/media/papers/2059
http://www.chiefdelphi.com/media/papers/1469

Everything is iterative. Email me if you have questions or find issues!

Re: paper: JVN's Mechanical Design Calculator 2016

The unique sheets for each WCP/VEXPRO gearbox should make things a lot more straightforward

Re: paper: JVN's Mechanical Design Calculator 2016

Thanks for keeping this up to date! I've learned a lot just from puzzling out your earlier versions. I'll definitely have to dig in this year on the calculations for the heteromotored gearboxes.

Re: paper: JVN's Mechanical Design Calculator 2016

I'm not sure I understand the Articulating Drive. What is it for exactly?

This is another awesome resource.

I would assume for butterfly, grasshopper, octocanum etc. Drivetrains with articulating wheels.

Re: paper: JVN's Mechanical Design Calculator 2016

Just posted an updated version:
  • Added RS-550 Motor Data which will be up on motors.vex.com
  • Changed the Motor selection lookup formula on the "non VEXpro" sheets to better allow for multiple iterations on the same sheet
  • Added additional "All MiniCIM" motor selection options on VEXpro sheets
  • Fixed some formatting that no one else would notice but was driving me nuts

Thanks to everyone who provided feedback. Enjoy and Good luck!

Wow @ the 550 power. I now get why we had issues with our elevator last year. Thanks for testing the 550.

Re: paper: JVN's Mechanical Design Calculator 2016

This is the first time I have worked on a drive base, and so I wanted to make sure that I was doing everything correctly.
  1. For the "Weight on Driven Wheels", that weight is distributed evenly among wheels, right? (say 25% if there are 4 wheels)
  2. What is the "Speed Loss Constant"?

Thanks in advance!

Speed loss constant accounts for the difference between actual speed and free speed of the motor. You can pretty much leave it at 81% for most FRC applications.

For "weight on driven wheels" if you have a 4WD robot with all wheels being driven then you would set that at 100%. If 2 of the wheels where non driven casters that would be 50% assuming a perfect weight distribution. Also for the purposes of this calculator omni and mecanum wheels are the same as traction wheels and wheel drop is ignored.
