The helical spring is of 3.10 mm cross sectional radius, pitch of 16.5 mm, coil
height of 102.5 mm consisting of CHEXA elements of average
element size of 1.0 mm. An enforced displacement of 52 mm in negative Y-direction is
applied on the top cross-sectional face of the spring and at the bottom face, the
constraints of DOF 1-6 is applied. A contact secondary surface is created for the
outer surface of the spring. Self-contact can be defined by defining same ID for
both secondary and main.
The material properties are:
Young's Modulus
210 x 103 MPa
Poisson's Ratio
0.3
Initial Density
7.9 x 10-3 ton/mm3

A maximum displacement of 52.103 mm is observed at the node 32017 for the spring, due
to the enforced displacement. A von Mises stress of 6923.392 MPa is observed at the
element 17345.Figure 2. von Mises Stress Contour for the Helical Spring
