Why different results by indicating solidworks simulation(3.8 N/mm) for getting the spring stiffness from The results that I got from a certified lab (4.7 N/mm)?
I think you have posted this in the wrong group. This is the CAM group.
You may want to post in the simulation forum.
Double check that the model geometry and properties of the SW material applied matches that of the real world spring. If the elastic modulus of the SW material is inaccurate then the results will be too.
