In a tension or hanger connection, the applied load produces tension in the bolts and the bolts are designed as tension members. ANALYSIS AND TEST RESULTS _ The analysis, of a split clamp connection for an 11 "-5K fl ange, was conducted us i ng " ANSYS " fi nite element program. "STIF 3" beam elements were used for simulating the flange bolts. The pipe extensions are pinned at locations equidistant from the earlier locations.

Jul 09, 2010 · Fatigue failures of bolted joints frequently lead to serious accidents of machines and structures. It is well known that fatigue failure is likely to occur around the first thread root of bolt adjacent to the nut loaded surface and the run-out of bolt thread. Stress concentrations increase the stress in one area so it is much higher than the average stress in the part. One example of stress concentration is the transition area in a bolt from the straight shank to the threaded section. The relatively high stress concentration in this area is the reason most bolts fail at the first thread off the shank. The bolt and the clamped part could be considered as a simple mechanical spring model, the sketch is shown as Figure 5. As shown in figure 6, bolt and part are displacing under load, fs and fp are measured from an initial position without clamping load; for the bolt this is the bolt head to nut face distance in the tightened configuration but I'm constructing a mesh using ANSYS 14.0 and I'm wondering if it's possible to match the mesh at the interface between two separate Unfortunately ANSYS won't let me do this. Does anyone have any advice to get around this problem?First of all, I created a simple solid cubic structure with coarse mesh in ANSYS WB Modal modulus. With the boundary condition is set as 1 face fixed, the first 5 natural frequencies (fn) given by ... The flange and Nut-Bolts force and contact stiffness factor are considered as parameters which are influ encing the joint deformation. The flanged joint is modelled and simulation using ANSYS 14 ... Bearing in bolts, all bolts loaded: (1) Bearing in members, all bolts active: (2) Shear of bolt: If the bolt threads do not extend into the shear planes: (3) If the bolts threads extend into a shear plane: (4) Edge shearing of member: (5) Member yield (6) Minimum proof load (7) Figure 8:Bolted Connection - Rear Support Typically, a bolt is tensioned (preloaded) by the application of a torque to either the bolt head or the nut. The preload developed in a bolt is due to the applied torque and is a function of the bolt diameter, length, the geometry of the threads and the coefficients of friction that exist in the Jul 09, 2009 · An experimental method for measuring clamping force in bolted connections and effect of bolt threads lubrication on its value. In Proceedings of the World Academy of Science, Engineering and Technology, The Fifth International Conference on Applied Mechanics and Mechanical Engineering, Bangkok, Thailand, December 2008, vol. 36, pp. 457 – 460. Bolted Connections in ANSYS Workbench: Part 1 - Endeavos ... Endeavos.com Sp = Proof strength = 85% of yield strength of bolt material. In recent versions of ANSYS bolt pretension can be applied on beam bolts. In earlier versions, APDL commands can be used. The contact between the mating plates is set to frictional. 3) Spring Bolts.

It is well known that fatigue failure is likely to occur around the first thread root of bolt adjacent to the nut loaded surface and the run-out of bolt thread. 2) Shear stress across the threads a) Average thread shearing stress for screw τ s = P / (𝜋dc X b X n) b= width of the thread section at the root. n- no. of threads in engagement 2.2.1.2 Stresses due to external Forces 1) Tensile Stress Bolt usually carry a load in the direction of the bolt axis which induces tensile stress in the bolt Ansys, Inc. is an American company based in Canonsburg, Pennsylvania. It develops and markets multiphysics engineering simulation software for product design, testing and operation and offers its products and services to customers worldwide. Ansys was founded in 1970 by John Swanson.Machine tool - Machine tool - Basic machine tools: Hundreds of varieties of metal machine tools, ranging in size from small machines mounted on workbenches to huge production machines weighing several hundred tons, are used in modern industry. They retain the basic characteristics of their 19th- and early 20th-century ancestors and are still classed as one of the following: (1) turning ... for 1/2" bolt with hex nut as the turning element Note: The following calculations are based on 1/2" dia. bolt Determine Torque vs. Tension Relationship major_diameter bolt 1 i in psi lb in in ksi psi 1000 minor_diameter bolt 2 i in dm is the effective contact diameter for the threads and is the average of major and minor diameters; It Compression Spring Overview. Century Spring warehouses the largest inventory of high-grade, straight, cylindrically-shaped compression springs in the world.A compression spring is an open-coil helical spring that offers resistance to a compressive force applied axially. The tested bolts exhibited a ductile fracture in which a cup-and-cone shaped failure surface forms in the threaded section, at the root of the nut. A parametric three dimensional finite element model simulating the tested specimen and attachments was constructed in the ANSYS Workbench environment.
