Hello friends
I modeled a power screw and its nut in mechanical desktop and imported this model into ANSYS 13.
I want to locate the stress concentration and also stress tensor over the screw. Attached photo is an overview of this model.
1- There is contact between screw threads and internal...
Thank you so much for your response.
I imported geometry from MECHANICAL DESKTOP and ANSYS already recognized contact regions. I defined a frictional contact for contact between screw and nut and after some searches I found out in 'define contact details' section under 'advanced menu', if...
Dear George
Thank you very much for your response. Actually, it is a lead screw which should change the rotation of the Nut to a linear motion to move 15 N force which is applied over it. I want to substitute the material of the lead screw which is stainless steel 304 with a special type of...
I tried to do a static structural analysis. My model consists of a lead screw, a nut and a pintle over lead screw. In reality Nut rotates around an axis (lets name this axis Y). Since lead screw supports are in such a way that it cannot rotate, this rotation causes the screw moves along the same...
Dear Onda
Thank you very much
I applied your advice and it was really helpful.
About the contact analysis, if I want to have the contact forces, should I use MASTER/DBALL instead of XDB? and is there any other regulation which should be applied?
Dear Onda
Thank you very much for your advise.
As I mentioned before I think this could be the major mistake that I have made. I try to correct it using your comment.
Could you please telling me how can I define the gravity value in Patran? Is it the Wt-Mass conversion in Solution parameters...
Dear dwallace1971
Thanks for your response and help. I don't think displacements are too large so that the non linearity be appeared in the results.
Anyway thanks for your kind response
I have imported a precise model from mechanical desktop to Patran and did a linear static analysis. In this analysis I used following units:
mm, kg, N, MPa
the material that I have used was stainless steel 304 with tensile strength about 250 MPa. But the result shows a stress tensor with...
