Hi guys,

I want to perform structure analysis on a spring that looks like this. The corrugated pattern is what is giving me trouble. I have left all mesh settings as default. the width of this corrugated pattern is around 0.4 mm and 3mm thick. I have tried using shell elements but am facing the same problem.. Any advice? Thank You

Hello Array,nUnder sizing option set capture curvature and capture proximity to yes.nRegards,nIshan. n

nSlice the inner and outer rings to separate them from the springs.nUse midsurfaces for the zig-zag springs and mesh with shell elements.nUse Bonded contact to connect the last edge of the spring to the face of each ring.n

Hi 1shan and peter, nI have created the shell models of springs and then used that to generate the mesh but it is giving me this error messagesnI want to get a result of directional deformation in the y-axis of a cylindrical coordinate system to calculate the degree of deflection of the spring. Please Help. Thanks alotn

why dont you use Beam simplification, This way you are simplifiyign the problem and moreover it supports vertex to face as bonded as u need as follows.nI know it is not upto your model properties, This way u can eliminate the small sized mesh,I hope this might solve and reduce DOF of your model. n

nI see there are two interpretations of midsurface on your solid geometry. I was thinking that the midsurface would go in the other direction, but what you did is also valid. If you take the approach suggests, you can collapse the model down to a 1D elements instead of 2D elements, and that is also a good approach.nIn either case, you use bonded contact to connect the meshes together. You should insert a Contact Tool under the Connections folder and Generate Initial Contact Status. Check that the contacts are Closed. If they are not, you may need to input a Pinball Radius to make them close.n
