Simulating a Quarter Car Model using Matlab - Simulink |Quater Car Model

[@hendryraja9360]

At 26:30 it should be -Kt(Zr-Zu) In the model we should multiply the Kt with Zr -Zu

How to give the Zr input ????

Sir how to give the Zr input in the model ????

@@adityakalhalikar4251 use an adder block and add - Zr as a constant to Zu before sending it via the Kt gain

do you have any idea related semi-active suspension system Simulink Quater Car Model? please make one video regarding that

[@bintokbino9612]

hi i have two questions 1.where did you get the value for force on unsprung mass Fw? 2. how to get value for road input Zr ? should i give it as a sin wave? very helpful if you could answer me asap!

[@david94549]

I believe: Multiply the masses by acceleration due to gravity (9.81 or 10), to get the force

[@naimharun7957]

are you already graduated?

[@ucnguyentrong3542]

Can we share code with each other? I just found out the code, but when used on 2 articles, one article will produce the result and one article will not work.

not getting the same output as you/...

[@vikassinha9557]

Please tell me how you have taken input signal 2 times in simulink model 1 is for road excitation and another for what If we derive equation of motion then also road excitation comes only once so please explain??

Good one Bro, need little clarity in your voice otherwise well done

@Hendry Raja how can I find the inputs of Fw and Fb?

Loved It ! Thanks bro.... make a video explaining basics of simulink.... :) Thanks.

Is this system active or passive?

[@malharikawade8925]

Sir how can do this in mobile app. I have not laptop sir please

[@sanagalasaisumanthreddy15b72]

In dynamic equation 5.13 it should be -Fw as Fw is acting opposite to unsprung mass acceleration(Fw arrow is shown upward).plz correct me me if i am wrong

[@hendryraja9360]

This is a equilibrium equation for Free body (m) with zero on the right. Then you bring the variable with the negative sign to the right it becomes positive. So , the Fw is on the left with negative sign. Them if you bring the fw to the right it becomes positive. Hope I cleared your doubt . Thanks for watching the video!!!!

while writing Kt why we took it as Zr but not Zr-Zu? ty

Ooh!!! Extremely sorry!!:( It should be written as kt(Zr-Zu) Thanks for your comment! I will correct it :)

[@mihirpatel7158]

hello sir, can you please help me out with obtaining the acceleration (x dot dot ) wrt time and also for the half car model how do i include the pitching angle i.e what block is to be used to include rotational degree of freedom

[@hendryraja9360]

Hey in order get your sprung mass acceleration just probe the scope b/w the sum block and integrator block in the sprung mass equation.

[@hendryraja9360]

That scope will give you simulation time vs spring mass acceleration

[@hendryraja9360]

For half car you need to do moment balance equation as you do for force balance equation.

[@mihirpatel7158]

@@hendryraja9360 thank you sir for the guidance and will try it out on my end

[@mihirpatel7158]

@@hendryraja9360 also is it possible to calculate the acceleration or velocity of the sprung mass wrt time when the car is moving at certain velocity (lets say 50kmph or 60kmph)

[@cutchunt6370]

can u explain it from scratch

[@张苏健]

spring rate is 4600N/M？

[@hendryraja9360]

Actually we are following SI units in this whole Simulation. So we need to give the spring rate in N/m. If you convert it from N/m to N/mm it will be around 46N/mm. Hope it answers your question!
