Is this Spring Damper System effective?

Click For Summary
SUMMARY

The discussion centers on the effectiveness of a Spring/Friction Damper system when the damping coefficient (B) exceeds the spring stiffness (A). It is established that the system will still function, as stiffness and damping serve different roles: stiffness resists deflection while damping resists velocity. The conversation emphasizes the importance of understanding the units of measurement for both properties, as they cannot be directly compared. Additionally, the term "work" requires clarification to fully assess the system's performance.

A real simple question but need confirmation:

When I have a simple Spring/ Friction Damper system where the value of the spring stiffness is say A(Nm) and the Damping is B(Nm). If the value is B > A, will the Spring system still work? Or will the spring just keep still no matter what the input torque is?

A stiffness and damping coefficient don't, and can't have the same units. Stiffness is a property which resists deflection or displacement while damping resists velocity. Check your units again.

Also...what does "work" mean?
