FINITE ELEMENT ANALYSIS OF BOLTED JOINT WITH COARSE AND FINE THREADS Janko D. If you want to really model a threaded connection you can specify the pitch diameter and actually 'turn' your screw to properly develop the shear stress under the bolt head for a bolted joint simulation without actually needing to model the physical threads (this can also be done using contact geometry corrections). Screw Thread Design Screw Thread Fundamentals A screw thread is defined as a ridge of uniform section in the form of a helix on either the external or internal surface of a cylinder. 6 In cases where the bolt preload force is unknown, a percentage of the incipient bolt yield force is assumed as the bolt preload force, for example, 65% of bolt yield gives a preload force of 41,000 lb. By calculation, using the external threads' minimum strip-strength and the average force per bolt thread, a HHN can develop at least 1. This contact method defines all of the thread characteristics. In Abaqus, bolts use a solid representation rather than the hybrid approach adopted by SOLIDWORKS. The rotation of a bolt (torque) at some point causes it to stretch (tension). We apply support to restrict these DOF. We've put together a handy thread length chart that is certain to make quick work of confusion and increase work production.

A screw thread is a ridge wrapped around a cylinder or cone in the form of a helix, with the former being called a straight thread and the latter called a tapered thread. Find quality bolts online or in store. Please enter your question or issue in the text box below. Contact elements work best when the element sizes on both sizes of the interface are similar, especially for nonlinear contact. Since bodies can be meshed independently, the Bolt Tightening Connection is designed to handle incompatible meshes. Supposing that the contact stress on load flank was uniform and that the helix angle was constant in each engaged thread, the axial component of contact stress integral on the load flank within each engaged thread should be equal to the axial load acting on itself; that is,. I want to model this problem using ANSYS WORKBENCH. Grade 8 bolts are often found in demanding applications such as automotive suspensions. When compared to UTS, 6g metric threads will be very similar to a 2A UTS bolt in terms of thread fit. Modeling bolt threads.
