Equivalent Damping: C1, C2, C3 in Parallel?

Click For Summary
SUMMARY

The discussion focuses on the parallel configuration of dampers C1, C2, and C3 in a damping system. It is established that dampers C1 and C2 are in parallel due to their identical velocity characteristics. The concept of "noting the location of force" is crucial in understanding how dampers C1 and C2 relate to damper C3, reinforcing that flipping C3 does not alter the system's behavior. This insight is essential for analyzing damping systems effectively.

PREREQUISITES
  • Understanding of damping systems and their configurations
  • Familiarity with mechanical components such as dampers and springs
  • Knowledge of system behavior in relation to force application
  • Basic principles of dynamics and motion
NEXT STEPS
  • Study the principles of parallel and series configurations in mechanical systems
  • Learn about the effects of velocity on damping behavior
  • Explore the concept of force location in dynamic systems
  • Investigate the mathematical modeling of damping systems
USEFUL FOR

Mechanical engineers, students studying dynamics, and professionals involved in system design and analysis will benefit from this discussion.

In this damping system it is obvious that the dampers C1 and C2 are in parallel. But I don't understand how "noting the location of force" in this system tells us dampers C1+C2 are in parallel with damper C3. Any help will be appreciated. Thnx

Component layout on the page is arbitrary. Mostly it's about esthetic values for presentation!

Flip C3 to the left hand side of the vertical line in the center (maintain the same component connections). What do you see now?
 
To the OP: In following gneill's advice, it might be useful to try and convince yourself why flipping C3 doesn't change the system behavior.

They are in parallel because they have the same velocity. Same case if they were springs, the displacement would be the same.
