What are the practical applications of springs in life?
1. Control mechanical movements, such as valve springs in internal combustion engines, control springs in clutches, etc.
2. Absorb vibration and impact energy, such as buffer springs in cars, train cars, vibration-absorbing springs in couplings, etc.
3, storage and output of energy as a power, such as clock springs, springs in the firearms.
4, used as a force measuring element, such as the dynamometer, the spring in the spring balance. The ratio of spring load to deformation is called spring stiffness. The higher the stiffness, the stiffer the spring.
According to the nature of the force, the spring can be divided into a tension spring, a compression spring, a torsion spring and a bending spring. The shape can be divided into a disc spring, an annular spring, a plate spring, a coil spring, a truncated cone vortex spring and a torsion bar spring, etc. . Ordinary cylindrical springs are widely used due to their simplicity of manufacture, their ability to be manufactured in various types depending on the loading conditions, and their simple structure.
