Hi!

Suppose you have two solid parts, that are screwed together (see pricture below). Is it possible to simulate preload between these parts?

(threads not modeled)

Yes, you can define the preload b/w two joining parts. Preload is applied based on the bolt size and nut factor. Loading must be in steps and once preload is applied, we need the lock the preload. 

Please refer: Modeling Bolted Joints of an Axle Assembly Using Ansys Mechanical — Workshop (youtube.com) and AIS course on Modeling the Bolt and Preload | Ansys Innovation Courses

Hello,

 

Yes, it is possible to simulate preload between two solid parts that are screwed together.

One way is to use the Bolt pretension object. More information related to that can be found in Ansys Help documentation at the following link:

On AIC, we have a learning track on Pre-loaded Bolted Connections which could be useful to you.

You can access it by following the link below:

Kind Regards,
