Spring (device)
A spring is a mechanical device that stores and releases energy. Springs are typically made of spring steel, although other materials can be used. They are used in a wide variety of applications, from automotive suspension systems to watches and toys.
Types of Springs[edit | edit source]
Springs come in several different types, each with its own specific applications and characteristics:
- Compression spring: These springs are designed to operate with a compressive load, meaning they get shorter when a force is applied. They are commonly used in automobile suspensions and ballpoint pens.
- Extension spring: These springs are designed to operate with a tensile load, meaning they get longer when a force is applied. They are often used in trampolines and garage doors.
- Torsion spring: These springs work by twisting. They are commonly found in clothespins and mouse traps.
- Constant force spring: These springs exert a constant force over their range of motion. They are used in applications like seat belts and counterbalances.
Applications[edit | edit source]
Springs are used in a wide range of applications across various industries:
- Automotive: Springs are used in suspension systems, valve springs in engines, and clutch springs.
- Aerospace: Springs are used in landing gear systems and control surfaces.
- Consumer goods: Springs are found in mattresses, toys, and pens.
- Industrial machinery: Springs are used in vibration isolators, valves, and actuators.
Materials[edit | edit source]
While spring steel is the most common material used for springs, other materials can also be used depending on the application:
- Stainless steel: Used for springs that need to resist corrosion.
- Phosphor bronze: Used for springs that need to conduct electricity.
- Titanium: Used for springs that need to be lightweight and strong.
Design Considerations[edit | edit source]
When designing a spring, several factors need to be considered:
- Load: The amount of force the spring needs to support.
- Deflection: The distance the spring will compress or extend under load.
- Spring rate: The amount of force required to compress or extend the spring by a unit distance.
- Fatigue life: The number of cycles the spring can undergo before failing.
