As you may have already seen in the SOLIDWORKS 2020 What’s New,\u00a0Pin and Bolt Connectors<\/strong>\u00a0in SOLIDWORKS Simulation now support\u00a0Distributed Coupling<\/strong>.<\/p>\n Here is new PropertyManager for the Bolt Connector, showing the\u00a0Distributed<\/strong>\u00a0and the\u00a0Rigid<\/strong>\u00a0options for the\u00a0Connection Type:<\/strong><\/p>\n From\u00a0Pg. 160 of the What’s New document:<\/p>\n The distributed connection produces more realistic stress and displacement fields at a bolt’s head and nut contact areas.<\/p>\n Note:<\/em><\/p>\n The Distributed Coupling option for Pin and Bolt Connectors is an extension of the Distributed Coupling option for Remote Load and Mass. The Distributed Coupling option for Remote Load and Mass first appeared in SOLIDWORKS Simulation 2019. See the Online Help topic\u00a0here<\/a>.<\/em><\/p>\n In this discussion, I propose to evaluate the influence of the Distributed Coupling option for Bolt Connectors.<\/p>\n To do so, I will use a simple model with a pre-loaded bolt. A bolt tightens two plates, one of which also received a Remote Load. The bolt has a 10,000N axial pre-load. We shall compare the results using three modeling techniques:<\/p>\n Note:<\/em><\/p>\n In the case of the bolt represented with solid geometry, a carefully chosen thermal load on the bolt shank creates the 10,000N axial pre-load.<\/em><\/p>\n See the Bolt Connectors 1.SLDPRT model in the attachment.<\/p>\n The screen capture below shows a comparison of the stress results on the plates for all three modeling techniques:<\/p>\n As you can see, the magnitude and the distribution of stresses are very similar for the top row (Distributed Bolt Connector and 3D bolt). The Rigid Bolt Connector gives different results due to the rigid bars in the formulation of the Bolt connector.<\/p>\n We can take a closer look. Compare the distribution of stress on the circular edge shown below between the study with the bolt represented with solid geometry and the study with the Bolt Connector using Distributed Coupling:<\/p>\n <\/p>\n Solid bolt:<\/strong><\/p>\n Bolt connector with Distributed Coupling:<\/strong><\/p>\n <\/p>\n As you can see the distribution shows the same pattern, and reaches the same maximum value of about 320 MPa in both cases. This clearly demonstrates the accuracy of the new Distributed Coupling option of the Bolt Connector. As a last note, it is worth mentioning that the solution time with the Bolt connector is about half that with the solid bolt. And the setup is much easier.<\/p>\n With the new Distributed Coupling option of the Bolt Connector, SOLIDWORKS Simulation sets a new high for ease of use and accuracy.<\/p>\n Bolt Connectors 1.SLDPRT<\/a><\/p>\n <\/p>\n Noteworthy Solutions from the SOLIDWORKS Knowledge Base<\/span><\/p>\n <\/p>\n That\u2019s it for this month.
