Relating variables: weight, gear ratio, power/torque to make design estimations

  1. Oct 22, 2014 #1
    hey all, I'm stumped so I thought I'd try posting here.
    I am in the early stages of design of a vehicle where we have a rough approximation of weight, no idea what gear ratios or power/torque to use yet, but have an acceleration requirement. I am trying to graphically model the relationship between some of these parameters to help get some design drivers. Any idea how I could proceed? Thanks!

    I should mention, nothing needs to even be close to exact, I just want some rough correlations plotted to compare different design alternatives. Thanks again!

    You can used this acceleration simulator. It gives you the acceleration potential of a vehicle based on power, weight and tire friction coefficient. It can be more precise if you know other vehicle characteristics like aerodynamics, weight distribution, etc. The theory behind it is explained on the website.

    Oh man. That's everything I wanted and then some.
