What are the practical applications of springs in life?
1. Control the movement of machinery, such as valve spring in internal combustion engine, control spring in clutch, etc.
2. Absorb vibration and impact energy, such as buffer springs under cars and trains, vibration absorbing springs in couplings, etc.
3. Store and output energy as power, such as clock spring, spring in firearms, etc.
4. Used as a force measuring element, such as a force measuring device, a spring in a spring scale, etc. The ratio of load to deformation of the spring is called spring stiffness. The greater the stiffness, the harder the spring is.
According to the force nature, the spring can be divided into tension spring, compression spring, torsion spring and bending spring. According to the shape, it can be divided into disc spring, ring spring, plate spring, coil spring, truncated cone scroll spring and torsion bar spring. Ordinary cylindrical spring is widely used because of its simple manufacture and various types according to the load conditions, and its simple structure.
