Governing Equations: Force on Damper w/ Damping Constant D

In summary, a governing equation is a mathematical expression used to describe the relationship between different variables in a physical system, while a damping constant D is a coefficient that represents the strength of the damping force in a system. The force on a damper is caused by the velocity or displacement of the object it is connected to, and the damping constant D can be determined experimentally or calculated using theoretical equations. A higher D value results in a stronger damping force, which can reduce oscillations and dissipate energy, while a lower D value may cause unwanted vibrations.

i want to know the governing equations regarding force application on a damper with damping constant D.
if you provide some force f to a damper , then how much force does it transfers to the other side.


f(input)------------>----------------------[d]--------------------->force output?
-------->>
v


v=relative velocity over the damper handle

There are several types of dampers. Depends on what the problem is, really.
 
  • #3
it is a simple damper, with a force dissipation of D*v
where v is the relative velocity across the damper
 

1. What is a governing equation?

A governing equation is a mathematical expression that describes the relationship between different variables in a physical system. It is used to model and analyze the behavior of the system under different conditions.

2. What is the force on a damper?

The force on a damper is the force exerted on the damper due to the relative motion between its two ends. It is usually caused by the velocity of the damper or the displacement of the object it is connected to.

3. What is damping constant D?

The damping constant D is a coefficient that represents the strength of the damping force in a system. It is used in the governing equation to calculate the force on a damper and is dependent on the material and design of the damper.

4. How is the damping constant D determined?

The damping constant D can be determined experimentally by measuring the force on the damper at different velocities or displacements. It can also be calculated using theoretical equations based on the properties of the damper material and design.

5. How does the damping constant D affect the behavior of a damper?

The damping constant D directly affects the magnitude of the damping force on a damper. A higher D value results in a stronger damping force, which can reduce the amplitude of oscillations and dissipate energy in a system. A lower D value can lead to less damping and potentially cause unwanted vibrations.
