What is the spring damping system

1 , but the actual spring system will have damping. If it is an additional damper, it only changes the damping in the application. But does it mean that the spring damping system is composed of two systems?You probably can't say that.. I don't know if the understanding is right or not.

2. A damper is a device that can slow down or eliminate mechanical vibrations, usually composed of springs, damping materials and mass. It can absorb energy and convert it into heat, thus reducing the amplitude and frequency of vibration. Dampers are widely used in machinery, aerospace, automobiles, construction, bridges and other fields.

3. Damping = In fact, it should be to prevent the damage to the item or the construction of the strong shock. The spring damping damping refers to the vibration amplitude caused by external action and/or the inherent causes of the system itself in the vibration of any vibration system. The gradually declining characteristics and the quantitative characterization of this characteristic.

How to find the damping coefficient of the spring mass damping system

1. For spring damping in the mechanical system, damping The unit of coefficients is usually per meter per second (N/(m/s) or per kilogram per second (kg/s). Damping coefficient: Damping Factor (Damping FactoR) refers to the ratio of the rated load (speaker) impedance of the amplifier to the actual impedance of the power amplifier.

2. The damping coefficient is only related to the material, not calculated. Generally, if you want to get accurate data, you need experiments.

3. For example, if you use a wire rope vibration isolator as a spring, you take the value of the damping coefficient, and then calculate it to look at the magnification of the resonance point. If the magnification is between 5-3, then the value is almost right. Keep calculating the value until the magnification is between 5-3.

4, or so-called factors affecting the structural damping ratio) are many. Mainly: (1) Material damping, which is the main reason for energy dissipation. ( 2) The damping of the surrounding medium to the vibration. ( 3) The damping at the junction of the node and the support.(4) Lose part of the energy through the support base. ( 5) The technological damping of the structure to vibration.

5. The impact of damping selection on actual seismic analysis. At present, the seismic response analysis of bridges is generally based on the time course analysis method of direct integration.

The physical significance of the frequency and amplitude characteristics of the mass spring damping system

The spring damping system refers to the vibration amplitude of the spring vibration system caused by external action or the inherent causes of the system itself. The characteristic of decline. The physical meaning of damping is the attenuation of force, or the energy dissipation of an object in motion. Generally speaking, it is to prevent the object from continuing to move.

Resonance refers to the situation when a physical system vibrates at a specific frequency with a greater amplitude than other frequencies;The physics requirements of middle school are not strict, and it can be considered that resonance is a special case of forced vibration. In forced vibration, when the frequency of the driving force is equal to the natural frequency of the object, the amplitude of the object is the largest.

ζ is the damping ratio. In general, with the continuous increase of ζ, the transient response graphic vibration amplitude of its system decreases and gradually tends to stabilize. When ζ=0, the system is in a non-damping state, and the transient response of the system is a periodic function of constant amplitude.

Frequency characteristics means that in an AC circuit, when the frequency of the input voltage changes, the load impedance will also change, so that it has different amplitude and frequency characteristics and phase characteristics, and the signal of different frequencies is different. This change relationship is the frequency characteristic.

The physical significance of frequency characteristics Frequency characteristics represent the "reproducation ability" or "tracking ability" of the system to sinusoidal signals of different frequencies.When the frequency is low, the input signal can basically be reproduced at the output side according to the original proportion, while when the frequency is high, the input signal is suppressed and cannot be transmitted.

The principle of the damper The principle of the damper is to reduce vibration by damping the interaction between the material and the mass. When the mechanical system vibrates, the spring in the damper will shrink and stretch to absorb the energy of the vibration. At the same time, the damping material also plays a role in converting the energy of vibration into heat energy, thus reducing the amplitude and frequency of vibration.
