There are three tools and plots in SOLIDWORKS and SOLIDWORKS Simulation that can be used to visualize and check the contacts in an analysis: Interference Detection Interaction Viewer and Contact Pressure Plots. Let?s take a brief look at how each of these work.

 

Pin connectors are faster because they don't require no penetration contacts and can be solved in a more linear way but wouldn't be commonly used in this way. Bonding the holes directly is probably easier but would give you no connector stress values and may over-stiffen the joint.

 

Explore bolted connections in SolidWorks simulation by loading the structural connection model applying steel material and defining a bonded global interaction alongside a local contact for the bolt.

 

Simulation models a bolt connector in a spider-like arrangement with (a) a beam element to represent the bolt shank and (b) rigid bar elements to represent the nut and head parts.

 

This document discusses using finite element analysis to simulate bolted assemblies in Solidworks Simulation. It notes that the best way is to use the bolted connection joint tool which accounts for variables like bolt torque thread pitch and strength.

 

Let?s look at an example of starting simple and working towards the complex with SOLIDWORKS Simulation that I hope will illustrate why you should start as simply as possible.

 

Bonded vs. Contact vs. Free Interactions of mated parts in SolidWorks Simulation of assemblies as well as the Connectors and the Pin/Bolt Check are discussed in this video.

 

Rather than having physical bolt geometry to mesh and interact with surrounding parts a Simulation Bolt Connector adds a simplified beam element to represent the bolt shank and rigid or distributed bars to the surrounding faces.
