2015年8月2日 · Since ξ is the ratio of damping coefficient of the system when critical damping occurs (Cc) to the damping coefficient of the oscillation (γ), ξ=γ/Cc. From this we have γ=ξ*Cc--(1) The expression for variation of amplitude with time is Ae^(-γt), so if we sub.

2018年9月19日 · I am very well aware of how to get the damping coefficient experimentally by observing a system in action. Given the dimensions and fluid properties of a theoretical viscous fluid dashpot, how d

The damping of a spring is calculated with: $$[\zeta] = \frac{[c]}{\sqrt{[m][k]}}$$ Where c is the 'viscous damping coefficient' of the spring, according to Wikipedia. m is the mass, k is the spring constant, and zeta is the damping ratio. How is the value of c calculated though?

2006年3月19日 · The damping coefficient is not a constant for a particular fluid. Velocity is not the only variable to which drag force depends, but you can reduce the other factors to a constant by determining the Reynolds number (which itself is a function of viscosity, geometry of the object moving through the fluid, etc.) and a number of other factors.

2015年2月23日 · So given a spring with unknown damping coefficient but known stiffness, you can attach a known mass to it and measure it's response to a disturbance and determine from that the damping coefficient. Since you are just going for aesthetics, you pick your damping constants arbitrarily.

2016年2月3日 · In lab for my physics of digital systems class, we were told to find the damping coefficient of a spring experiencing simple harmonic oscillation.

2014年9月14日 · However, it does not include information about the coefficient of torsional viscous damping which I need for a Simulink model. The units for torsional viscous damping are Nm.s/rad, and the following relevant information about the motor is given: Friction torque: 0.06Nm Mechanical time constant: 1.7ms Nominal speed: 4500rpm (471.24 rad/s)

2021年4月22日 · It illustrates the damping-with-oscillation interpretation of the second order response and it's application to obtain a simple system ID technique. Please see my post for the relationship between the variables $\beta, T$ in this post and the natural angular frequency $\omega_n$ and damping coefficient $\xi$ of the system, which are required to ...

2014年3月23日 · Hi all, I am trying to calculate the damping coefficient of a linear viscous dashpot/damper given the dimensions of the piston, and the dynamic viscosity of the damping fluid. I have found this calculator, but does anyone know the equation that it uses...

If the damping coefficient approaches zero, the differential equation we are looking for needs to approach the 2nd equation you wrote (the one for the physical pendulum). Therefore, we can conclude that the only thing we have to modify in the last equation to get the equation for a damped physical pendulum is to change g/L into mgL/(I_CM+mL^2).
