Quarter car suspension model

Thanks for explaining this 10x clearer than my professor. You rock!

For those wondering, there is a mix-up of notations in the Equations of Motion. m₁ẍ₁ should actually be m₁ẍ and m₂ẍ₂ should actually be m₂ÿ. The double dot notation means acceleration and the two equations of motion are in the form mass × acceleration=∑force .

why is not f1 = - ks (y -x) as hooke's law states that a spring acts opposite to the direction of its displacement from the equilibrium position?

[danielvolinski]

There should be a hidden constraint here: y>x. The option y<x is mathematically possible, but not physically. How do I take that constraint into consideration? I am running several simulations of this system with different parameters and I always get at some point in the simulation that y<x which means that m1 and m2 go through each other! Thanks.

is it reasonable to ignore the dashpot (?), the absorber characteristics of the tyre? It's not perfecly elastic, is it?

[muslimwarlord]

it is (x-y) not (y-x) because when you the the programming, the signal source will come from the road, r . if you use y-x, since that there is no initial value to start with y, then your programmed going to give error.

Hello sir, could you please make a video for the half-car model (4DoF) and the full-car model (7DoF) or perhaps leave a link for some content that explains these two models? Thank you.

[sakthimurugan]

sir, kindly tell me which tool or software you use for creating this video.. your video are nice and clearly expressed.

thanks sir.

sir, why a quarter car or half car model is analyzed instead of full car model?
Thank You

why we dont put the gravitacional force at the diagram?

[laraelnourr]

why is the stretch in the spring y-x and not x-y?

[wenuradesilva]

why we here not using the weight of two masses can you explen this to me

[rubeensharma]

m2.y2'' instead of m2.x2''!!

The system is only dampened if you hit a puddle ;)

how to find Kw for this quarter?I need for my thesis to find Kw..

[tarekalkanbar]

I couldn't understand what are (x double dot one ) and (x double dot two)
