Abstract:
The spring is one of the mechanical elements
making maximum use of the elasticity of material and
the energy absorption capacity. It has such functions
as shock absorption, anti-vibration (suspension spring),
maintenance of constant force or torque (valve spring,
spring washer, watch spring), and indication or adjustment
of load and torque (scale spring, manometer).
Mainly, the material of spring steel is heated
(approximately 900°C) for forming to be formed into
the spring, with the material used hereby called the
hot-formed material. For the reason, it is applicable
mainly for large-size plate spring (leaf spring), coil
spring and torsion bar rather than small-size spring.
