Discussion Overview

The discussion focuses on obtaining the stiffness and damping coefficients for the front suspension of a VW Golf IV 1.6 16V (2003) to estimate the transfer function of a quarter car model. Participants are exploring technical specifications and methods for calculation.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant requests specific stiffness (K) and damping (C) coefficients for the VW Golf IV to complete their work.
  • Another participant suggests that the original poster should provide more specific details about their needs.
  • A different participant inquires about the type of suspension and offers to help calculate the stiffness if details about the coil spring are provided, while noting that the damping coefficient may require testing.
  • One participant recommends reviewing race car suspension classes on the forum for insights on weight transfer and required components.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the specific coefficients needed, and there are multiple approaches suggested for obtaining the required information.

Contextual Notes

There are limitations regarding the availability of specific technical data and the need for empirical testing for the damping coefficient.

stiffness and damping coeficients of a VW Golf

Hi!
I need information about the VW Golf IV 1.6 16V(2003). I need to estimate and calculate the transfer function of the quarter model car so i need the coeficients of stiffness (K) (N/m) and damping (C) (Ns/m) of the front suspension, its important to complete my work so i'll be very grateful if someone can help me.

Thanks!

Hi cvy-extroid - as a fellow new person to PF I feel bad that you haven't had any responses - perhaps you can be more specific as to your needs?
 
Hi! cvt-extroid
what is Suspension type.I think that is technical data.Do you know data of coil spring
example total turn,wire diameter which if know I can calculate for you but damping coeficient I think you should test and calculate.
 
read race car suspension class on this forum...you can get pretty good idea of weight trnasfer and required springs shocks etc...
