For those who are not acquainted with leaf springs related terms, here are given some helpful definitions:

• Axis: It is a straight line that traverses the central point of any object.

• Active Coil: It is a coil in the coil-spring that deflects or moves under load

• Beam Spring: A simple type of spring that is made of a flat, smaller metal piece and is mainly put into use in several automotive applications including suspension system. It is sometimes also known as leaf springs or flat springs.

• Buckling: It is a kind of damage to coil-compression spring in which the unit is distorted permanently after attaining rock-hard compression on account of working under heavier loads than it is able to hold out. Buckling actually appears just like side ways deflection.

• Clash Allowance: This term refers to the amount of room available between the unit’s solidity height under maximum loads and solid-compression height. Coil-compression springs are usually designed with ten percent difference between solid compression and maximum load-height to evade coil clash.

• Chassis: It actually refers to the framing of equipment, such as clothes or car washer.

• Deflection: It is the degree of adjustments in shape on the application of the force. Springs turn aside and alter their shape so as to take up forces.

• Dampen: Dampen means lessening the application of force. Spring units in auto suspension systems damp forces when vehicle runs into road bumps.

• End Coils: These are end coils in coil spring units that are utilized to fasten springs to machine. They can also be squared to increase the strength.

• Flat Spring: It is a simple spring unit made of flat, small piece of metal, and is utilized in automotive applications. Flat spring is also called leaf springs and beam springs.

• Foot pounds: It is basically a torque measuring unit, used in the English system.

• Free Length: It is a variable required when placing order for springs, and represents the length of spring under no-load.

• Inch Pounds: It is also a unit that is employed to gauge torque.

• Kinetic Energy: The energy which is in motion is usually called kinetic energy. In relation to springs, it is the energy which the spring discharges when coming back to original shape, upon deflection.

• Load/Load rate: The force which is applied to any structure or material is called load. Springs take up and release energy from load. The rate at which force is applied to a module is called load rate.

• Mechanical device: This is the device that works by producing motion and force. Springs are considered mechanical devices as they exert and react to a motion and force.

• Mechanical system: It refers to the grouping of many components working together so as to do useful work. Leaf springs are often employed in ‘mechanical systems’ for storing energy or humidifying forces.

• Multi Leaf Springs: These springs are made by grouping several metal pieces. They can humidify friction, but are able to accept force in one-direction only.

• Overload stop: It is basically a circumstance in which end-coils of compression spring stop supporting machine because the unit is overloaded and cannot operate. Overload stop is an imperative safety measure because it can evade machine damage and injury.

• Pre-loading: The method utilized by manufacturers to improve the operating abilities of coil springs is called preloading. It incorporates creating a relatively longer spring and applying a certain amount of force before being delivered to customers.

• Set: It is a kind of permanent distortion and occurs when springs are subjected to unacceptable high-load conditions. A compression spring must not experience more than 2% set.

• Shear strength: It refers to the ability of a material to stop forces that try to make it deformed permanently. Too much sheer twist can even cause the spring to break down.

• Shearing: The damages that occur when springs break due to the application of heavy loads causing upright strain or excess transverse are called shearing.

• Shock Load: This load characterizes a huge amount of load and extreme speed.

• Shot Peening: It is a method utilized by spring manufacturers to augment the capabilities of metal employed in the components. In this procedure, the metal surfaces are blasted, which ultimately boosts the material’s capability to withstand many kinds of damages.

• Spring: It is a device employed to moisten and apply load, store energy, and control vibration and motion.

• Spring Rate: It can be defined as the amount of load required to condense a spring.

• Spring washer: The component which is mainly used with screws to reduce stress and offer immense flexibility, is called spring washer.

• Static load: It is the kind of load that preserves the same amount of load and direction throughout operation.

• Stress: It is load that tries to distort an object or structure. Deflection is the key source of stress for a spring.

• Tensile load: It is the force that tries to pull apart an object. The extension springs are typically designed to hold up tensile load.

• Torque: It is a force that causes rotation, and a torsion spring is made to dampen or apply torque.

• Torsion bar: This spring type consists of a bar that distorts slightly on the application of force, and is most used in a suspension system of vehicles.

• Torsion Load: It is another spring type that moves torque in the machine by arching into one or two-directions, based upon the kind of torque required.

• Torsional Strength: It is a kind of shear strain that tries to bend an object against itself. Springs can become distorted if it goes beyond the limit of torsional strength.

• Unloaded: This term is used when the spring is not experiencing any load.

• Volute Spring: This kind of spring is manufactured by wrapping up metal strips inside each other so to make a pointed shape with almost all metal pieces touching. It is relatively expensive, but is much more stable than coil springs because coils touch.

• The Working Range: It refers to an operating condition within which a spring can operate without deforming permanently. Some conditions that determine working range include the kind and amount of load support, and speed of the operation.
