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

Click For Summary

Discussion Overview

The discussion revolves around the effects of adding a damper to springs arranged in parallel, exploring the implications for stiffness and system behavior. Participants reference theoretical concepts and mathematical formulations related to damped harmonic oscillators.

Discussion Character

  • Technical explanation, Mathematical reasoning, Debate/contested

Main Points Raised

  • One participant inquires about the specific method for incorporating a damper with springs in parallel, referencing the formula for total stiffness.
  • Another suggests placing the spring in a viscous medium, implying that real springs exhibit damping characteristics.
  • A third participant directs attention to the concept of damped harmonic oscillators, indicating a potential resource for further understanding.
  • A later reply introduces variables for spring and damper coefficients, proposing a total impedance formulation in the Laplace domain.

Areas of Agreement / Disagreement

Participants present various approaches and ideas regarding the interaction between dampers and springs in parallel, with no consensus reached on a specific method or outcome.

Contextual Notes

The discussion includes references to mathematical formulations and physical principles, but lacks detailed explanations of assumptions or dependencies on specific definitions.

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
