Surge in springs is avoided by the following methods.
(i) The spring is designed in such a way that the natural frequency of the spring is 15 to 20 times the frequency of excitation of the external force. This prevents the resonance condition to occur.
(ii) The spring is provided with friction dampers on central coils. This prevents propagation of surge wave.
(iii) A spring made of stranded wire reduces hte surge.

What is surge in springs?
When there are impact loads on the springs, the stress propagates along the spring wire. The end coil of the spring in contact with the applied load takes up whole of the deflection and then it transmits a large part of its deflection to the adjacent coils. This wave of compression travels along the spring indefinitely. Resonance will occur depending upon time traveled.This results in very large deflections and correspondingly very high stresses. Under these conditions, it is just possible that the spring may fail. This phenomenon is called surge.

What is surging in axial compressors?
Surge is defined as the operating point at which the compressor peak head capability and minimum flow limit are reached. The compressor loses the ability to maintain the peak head when surge occurs and the entire system becomes unstable. Under normal conditions, the compressor operates to the right of the surge line. However, as fluctuations in flow rate occur, or under startup / emergency shutdown, the operating point will move towards the surge line because flow is reduced. If conditions are such that the operating point approaches the surge line, the impeller and diffuser begin to operate in stall and flow recirculation occurs. The flow separation will eventually cause a decrease in the discharge pressure and flow from suction to discharge will resume. This is defined as the surge cycle of the compressor.The surge cycle will repeat itself unless control systems are installed or operational changes are made to bring the compressor out of the surge cycle. The surge cycle may result in a small or large flow reversal period depending on the discharge gas volume and the pressure ratio. Chronic surge is characterized by intermittent periods of small flow reversal that may not cause severe damage to the machine. Acute surge is more pronounced, usually due to a rapid transition across the surge line. Any surge event can cause severe damage to the thrust bearings, seals, and the impeller.
Can reciprocating compressor surge?
Compressor surge only occur in centrifugal compressors. reciprocating compressor don't as they increase pressure by volume reduction, unlike centrifugal compressors where they increase pressure by converting kinetic energy to potential energy (pressure).

How do you use surge a sentence?
The strong wind and spring high tide caused a surge of seawater to flood the marshes even as far as the coast road.
What is the most likely explanation for the phenomenon when you eliminate the impossible?
The most likely explanation for the phenomenon of eliminating the impossible is that what remains, no matter how improbable, must be the truth.
Why do most aircraft reciprocating engne use more one spring on each valve?
to prevent surge
A local rise in sea level near the shore that caused by strong winds from storms such as those from a hurricane?
This phenomenon is likely due to the storm surge associated with hurricanes. Strong winds from the storm push water towards the shore, causing a temporary rise in sea level. This can result in coastal flooding and damage to properties near the shore.
Why are surge protectors recommended with the use of a computer?
If the computer operates in an environment prone to fluctuating current/voltage, a surge protector will reduce or eliminate (most of) the variations and protect the sensitive electronics in the equipment. Failure to protect from voltage spikes could result in damage to hardware and/or loss of data.
What is the purpose of two or more valve springs in aircraft engines?
If only one spring were used on each valve, the valve would surge and bounce because of the natural vibration frequency of the spring.
Is surge a verb or an adjective?
Surge is a noun (a surge) and a verb (to surge). It is not an adjective.
What storm is just like a tsunami?
No storm is. However, one phenomenon that occurs during some storms can resemble a tsunami. Large, powerful storms such as hurricanes can drive a mass of water known as a storm surge onto land. This storm surge behaves somewhat like a tsunami.
How many surge commands in kingdom Birth by Sleep?
There are five: Payback Surge, Thunder Surge, Fire Surge, Barrier Surge, Vitality Surge.

What is a "newpoint surge", and how does it work?
A Newpoint Surge is used to protect electronics from being fried from lightning and other surges that may occur. By plugging anything that uses electricity into a nepoint surge, it is protected from 20,000 amps.
