I am trying to find out how an electrical damper works. I know that it slowly reduces the amplitude of a current or voltage but don't know how, or even what any circuit would look like. I am not an electrician but know basics like capacitence, impedence etc so if you can help and can explain in...
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...
Homework Statement
I am asked to write down the equation of motion of m with respect to O, hence show that x(t) satisfies the differential equation.
m\ddot{x}+r\dot{x}+kx=mg+kl_0+m\ddot{y}
See attached diagram.
Homework Equations
I have the force of the spring H, the Damping R and...

Hey guys,
I was just wanting to know, if there is a special way to add a damper in spring in parallel (as per the image below).
i know that springs in parallel is; 1/k(total) = 1/k1 + 1/k2...
Please guide me towards the "differential equation of motion" for the following 2 DOF Spring-damper system.
And furthermore, if above system is in a uniform speed rotating frame, then what can be the effect on this system?
Thank you very much.
Consider a system with m = 100, c = 100 and k = 400. If y(t) = 3sin(1.5t), determine x(t) and ft(t).
I don't have a picture handy but the equations for the system turn out like this.
mx''+cx'+kx = cy' + ky
Transfer function = x/y = cy' + ky / mx'' + cx' + kx
then w/a laplace...
[b]1. Please help. How should I derive the equation for the damper and spring at right side of the mass(as shown in attach pic)? Can I combine both together as Fd + Fs or I need to have set a point between the spring and damper? Thanks.
I am trying to write a system model for lowering a mass into water. In my system model, I have a mass hanging freely from a spring and damper connected in parallel. I then try to equate the damping coefficient to the drag experienced by the mass.
I have provided the system equation...
Hello Everyone, I'm hoping you can help with this.
I need to set up a test on a dynamic test rig which can simulate shock impacts upon a spring (actually it's a hard rubber based component).
The test has previously been done on a rig which dropped a mass of 78Kg onto the part until...
I am trying to do a FEA of a viscoelastic damper. Should I use Ansys11 to do the analysis or Ansys Workbench 11.
If I should use Workbench, can anybody give a good link where I can find tutorials on performing FEA on viscoelastic dampers.
I'm sure I must be being a bit dim here, but I can't work this out!
I have a mass-spring-damper system, as shown in the attahed picture, in which i have a mass suspended between two springs and dampers, each of which are attached to a fixed surface. he two opposite surfaces are part of the...
From a mathematic, linear differential equation point of view, and energy storage point of view, the concepts I mentioned in the topics are the same (I remember this being a concept in modeling control systems.)
My question is, what are the same basic elements in other topics: thermal...
Hi everyone,
I want to know if anyone has informating about A/P yaw damper system. How does it work? and give me some pic with dawing the system, electrical "I mean." but if you can give me the electric servo yaw damper. you can find the Block diagram in book call "Avionics fundamentals" which...
Hello everyone!
I need to solve the angular acceleration on a sunglass bin on an over head console of a car.
The sunglass bin rotates open.
It has a torsional spring and gravity that forces it to open and a small rotary damper that slows it down. There is a gear on the sunglass bin and on...
