SHOT PEENING
A set of ‘n’ single springs in parallel (figure 21 – c) results in the following without considering friction.
Spring load
Formula 20
Spring Deflection
Formula 21
Unloaded Stack Length
Formula 22
In this case the spring load must be multiplied by the number of springs in parallel, where as the deflection remains as for a single spring.
For springs in Group 3 with contact flats and reduced disc thickness, t must be replaced with t’ in formula 22.
