Take engineering to new heights and precision with a leading provider of complete engineering simulation services. Specializing in the application and training of an expansive range of Finite Element Analysis simulation capabilities, Kx Simulation Technologies, Inc. has the tools and experience to bridge the gap. Assembling bolts on the model will result in surface errors during importing the model into ANSYS. So I want to compensate the bolt pretension loads by applying an equivalent load on bolting ...

Sep 11, 2017 · A more detailed list can be found in the ANSYS Help, in the Release Notes. Number 2: A major new feature that became available in 18.0 is Topology Optimization. We’ve written more about Topology Optimization here. Number 3: Another really useful enhancement in 18.0 is the ability to define a beam connection as a pretensioned bolt. This means ... of ISO Metric bolts of different size such as M8, M10, M12, M16 and M20 bolt having 1.25, 1.5, 1.75, 2 and 2.5 mm pitches respectively are used for testing. The maximum stresses developed and deformations occur due to pretension load appliedon nut bolt assembly are obtained by finite element method using ANSYS Workbench version 14. The validations
After the bolt is imported into ANSYS Design modeler, the bolt shank surface should be split as shown via projection method using the nut face edge. The splitting of the shank at the nut face is very important since pretension load in mechanical will split the shank body in half and pull it together to impose the pretension load. Aug 24, 2018 · Preload/pretension: Advantages | Applications Preloaded Bolt Bolts are tightened such that a high tension, usually above yield strength, is developed in the bolts, these are called preloaded bolts.
Pre and Post processing tool to create groups of rivets, bolt pretension, simplified bolts and advanced bolts with thread contact section. Rivet and bolt results can be evaluated according to Eurocode 3 and VDI 2230. May 23, 2016 · Bolt Modeling in ANSYS—Method 1. ... This method is a conservative approach where large safety margins are common. Pretension is not included in this method. Note ...

The non-linear model is solved in ANSYS with bolt pretension in load step 1 followed by 4 load steps with a “unit load” of 100kN in the x-direction of the two local coordinate systems. First in the negative direction, then in the positive, i.e.: LS1: Pretension LS2: Pretension + F5 = -100kN LS3: Pretension + F5 = +100kN Numerical modelling of connection is carried out by using the following parameters: geometric and material nonlinearities of the elementary parts of connection, bolt pretension force, contact between column flange and end-plate, washers and plated elements, bolt-shank and hole, and friction. 2. There were pretension force on the right image (force 2500N and lock) that's why there is a step in deformation of a bolt. I think that is how ANSYS apply pretension (It cuts bolt in some point and adds forces to create pretension; see image1). It would be great if I could get rid of it somehow to see real bolt deformation. Have a nice day,
