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.
Which is the best robot in bots acclaim?

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).
What is Stiffness of a helical spring?
a helical spring has N turns of coil of diameter D, and a second spring made of same material and of same wire diameter has N/2 turns of coil of diameter 2D. if stiffness of first spring is k, then stiffness of second spring is

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.
Why does a compressor surge happen?
Compressor surges can happen when there is a line spike, during storms or when other equipment is plugged in on the same electrical line. An industrial surge protector can help eliminate power surges.
Why do most aircraft reciprocating engne use more one spring on each valve?
to prevent surge
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.
How much is a north face bookbag?
They currently (Spring 2012) range from about $30 (the Homeslice - child's backpack) to about $125 (the Surge Backpack).
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.
