Hi! I know that for line springs preload is calculated by diffrence between two-point size on model and spring free length. Are there some method to specify angle preload for torsional spring?
Ahhh, my apologies. I thought you were asking how to calculate the load of a torsion spring.
I have never used Solidworks Motion, so I have no idea.
Maybe this will help?
How do you specify torsion springs
See the attached PDF file.
Should answer your questions.
Thank you! But I was referring to the ability to pre-load the torsion spring in its definition in Solidworks Motion Study. Let me rephrase that. The initial position of the Assembly of the linear spring can be pre-compressed or stretched by setting the free length of greater than or less than the distance between the points of attachment of the spring. How can the torsion spring be angle preload in the initial position of the Assembly?
Here is my example. Two rods connected by a hinge. The hinge is the value of angular stiffness 1000 N*mm/deg. One rod is secured in position. The second rod in the initial position has an angle of inclination of its axis relative to the first rod. The hinge is already loaded at this angle. And at the beginning of the study the second rod is returned to the horizontal position
