Spring Design

Design information for engineers, such as spring calculation formulas,

which are the basis of spring design, can be found here.

2.Numerical Values Required for Calculation

①Gaps between plates

②Maximum effective radius

③Minimum effective radius

④Pitch angle

⑤Coefficient determined by t/b

⑥Transverse elastic modulus

⑦Spring constant

3.Spring Characteristics When the Spring Starts Reaching the Point Where the Horizontal Spacing between Adjacent Plates Becomes 0
