You need mass to damp which is why it's called mass damp... ugh never mind.
It's called a tuned mass damper because it involves mass AND damping. Two different things.
A tuned mass damper is a resonant system which, like most every other resonant system involves a mass, a spring, and, in any real world resonant system, damping.
The mass of the mass and the stiffness of the spring combine to establish the resonant frequency. The Q of that resonance (i.e. its peakiness) is determined by the damping.
Damping is a loss mechanism, either parasitic or intentional. Damping is that which ultimately converts mechanical energy into heat. Such as the friction within a real world spring.
The mass, spring and damping of a mechanical resonant system models electrically as inductance, capacitance and resistance. The inductive reactance of the inductor and the capacitive reactance of the capacitor establish the resonant frequency of the circuit. The resistive element in the circuit is the damping and establishes the Q of the resonance.
So again, adding mass does not add damping. Mass is not a loss mechanism. It is an energy storage mechanism. Adding mass will only change the resonant frequency. To change the damping, you need to add a loss mechanism which converts the mechanical energy into heat. And that's precisely what damping materials such as Sorbothane are designed to do.
|All major designers use spikes except the stuff you find at best buy for $40. I guess they got it right with plastic and rubber feet while high end designers are confuse?|
|Maybe you can enlighten them with your very own law of physics.|
You'll find that mass and damping are not one and the same. They are two entirely different things.
