S-Ply® vs. acél
Substitution of steel spring by S-Ply® leaf spring
Due to their greater spring action, steel spring packages can be replaced by fewer or even one S-Ply® leaf spring for many applications.
Example:
a) Substitution
b) Cost calculation
Steel leaf spring:
155 x 25 x 2 mm
1 package of 10 springs
S-Ply® leaf spring:
It is essential:
with:
hS-Ply = Thickness of S-Ply® spring
hStahl = Thickness of steel spring
nStahl = Amount of steel springs
EStahl = Modulus of elasticity (here 210.000 N/mm2)
ES-Ply = Modulus of elasticity of S-Ply® leaf spring
(here 28.000 N/mm2)
The result is that 10 steel leaf springs with
a thickness of 2 mm each can be replaced by only
1 S-Ply® leaf spring with the thickness of 8,5 mm.
