How Does Adding a Damper Affect the Stiffness of Springs in Parallel?

Click For Summary
SUMMARY

Adding a damper in parallel with springs affects the overall stiffness and impedance of the system. The total stiffness for springs in parallel is calculated using the formula 1/k(total) = 1/k1 + 1/k2, while the total impedance in the Laplace domain is represented as k + sc, where k is the spring coefficient and c is the damper coefficient. This configuration is relevant in the study of damped harmonic oscillators, which can be further explored in the provided Wikipedia link.

PREREQUISITES
  • Understanding of spring mechanics and stiffness calculations

Hey guys,

I was just wanting to know, if there is a special way to add a damper in spring in parallel (as per the image below).

i know that springs in parallel is; 1/k(total) = 1/k1 + 1/k2...

Put the spring in a viscous medium.
Actually any real spring is a little bit like that.
 
spring coeff: k
damper coeff: c

total impedance is k + sc

in laplace domain
