how can I calculate a vehicle's axle load distribution and center of gravity changes?

Hello Guys,

I am a newbie at Matlab and I'd like to make a study about a vehicle's axle load and center of gravity changes.

I have a 6 x 6 vehicle baseline that I know the axles loads (unloaded vehicle) and I need to include some additional loads to this baseline vehicle. I'd like to understand the axles loads and CG changes after these new loads. Do you know how to do this simulation using Matlab or Simulink? Could you help me?

(1) Derive all calculation equations on weight distribution, in other words, the relationship between distributed loads and distances between axles

(2) Determine what is/are the input variable (s). Presumable, weight of the truck and additional load (additional load or unloaded weight)

(3) Determine what need to be computed. Presumable c.g. coordinates

(4) Write a code.

Here is one plain example for code writing. (Note this is a plain example how to write a code and NOT a weight distribution calculation formula):

% Equation: x_CG = (W1/W2)*x1; W1, W2, x1 are known variables and x_CG is to be computed.
W1 = input('Enter W1  =   ');
W2 = input('Enter W2  =   ');
x1 = input('Enter x1  =   ');
x_CG = (W1/W2)*x1;
fprintf('The location of C.G. along x axis: x =  %f [m] from front axle \n', x_CG)

Thank you Sulaymon,

As a new user, my programming skills are not yet good. Do you know another way to simulate the issue, maybe inside Simulink or another Matlab tool?

Sort out all equations and then I can guide you how to write a MATLAB code or build a Simulink model.

All the best.
