Question #171324

An accelerometer has the following properties:

Stiffness k = 500,000 N/m

Mass m = .01 Kg

Damping coefficient c = 95 N-sec/m

What is the damping ratio of the accelerometer?

Expert's answer

The damping ratio of the accelerometer can be found as

where *c* - damping stiffness coefficient, *k - *stiffness, *m* - mass:

"\\zeta=\\frac{95}{2\\sqrt{5\u00b710^5\u00b70.01}}=0.67."
