Try this bolt pattern force distribution calculator, which allows for applied forces to be distributed over bolts in a pattern. About this Calculator What is it for? The minimum required bolt load divided by the number of bolts in the flange will determine the minimum f, or force, needed to use the torque equation. Tension tooling, powertrain couplings, and accessories designed for power generation applications. Caution. F t,Ed is the applied tensile load and F t,Rd is the tension resistance of the bolt. Due to a variation in friction we recommend in extreme cases to check with the bolt manufacturer, as this chart represents a guideline only. Informate’s bolt load values are independently verified to ensure leak-free joints, every time. the bolt load is transferred from the Tensioner to the joints hexagon or round nuts. Boltplus Bolt Load Calculation is a free app and what makes it different from similar apps on the market is the speed, ease of use and ability to save all the calculations against a project. Force = Bolt Load = ?

Bolt Load Capacity Tables To BS5950 Part 1. But also the possibility to make a request for a special tensioner or enquire about your selections directly in the app. To achieve the benefits of the preloading, the clamping force must be higher than the joint separation load. The Bolt load loss is a direct loss of stud elongation, this is due to many different factors, such as thread deflections, radial expansion of the nut and ‘bedding in’ of Shear Capacity at 160N/mm THREADS IN SHEAR PLANE. mm. A t = Tensile Shear Area of Bolt S p = Proof Load of Bolt (or some percentage less than 100% of yield load of bolt, typically 85 % of yield S y) c = 0.75 For connections requiring reuse c = 0.89 For permanent connections . 8) NOMINAL BOLT SLIP LOAD - This is the nominal slip load shear loads applied to the joint should be below this value. Results are in Newtons. Bolt Stress window, displays bolt stress, bolt load and % of bolt yield. Bolt Load Calculator. Tension elements: Elongation due to axial load Calculator: Calculates elongation (as well as stress and strain) for prismatic elements subject to axial force.. Wood tension element capacity Calculator: Calculates capacity of a wood tension element based on allowable tension on net area (reduced by bolt holes) and, if desired, row and group tear-out. That figure is about right for a low tensile bolt. With too little clamping force, the joint may loosen. Product Lines. Clamp load is also known as preload or initial load in tension on bolt. To download BoltUp, or for a free 7 day trial of the Informate bolt load calculation software go to: joint-integrity.com. RE: ASME flange calculations design bolt load Vs. applied bolt load … Quick Input Quick input provides input of all data in only one dialogue window. Instrumentation. Bolt load is calculated from the design stress (SAE, ISO or ASME), bolt size (UNC, UNF, BSW or ISO) and the tensile area (ANSI or ISO threads). Proof load is defined as the maximum tensile force that can be applied to a bolt that will not result in plastic deformation. F v,Ed is the applied shear load and F v,Rd is the shear resistance of the bolt. Some notes from ISO 898 metric screw threads standards: The 2) In section Head Size and Type either select one fastener ISO with the "Select Standard for Type" option or enter manually the type and whether the fastener is socket or not in the right part of the page, once you have selected Custom option.. 3) Enter strength class of the fastener. K – constant d – diameter of bolt (m, in) F – axial bolt force or load (N, lb) BOLT LOAD CAPACITY TABLES TO BS5950 PART 1, 2000 THE ULTIMATE LIMIT STATE (ie FACTORED APPLIED LOADS) GRADE 4.6 BOLTS In Grade 43, bearing capacity = 460N/mm, for e 2d. COMMITTED TO SUSTAINABLE PRODUCTIVITY Both lateral (single and double shear) and withdrawal capacities can be determined. Note: tensile axial forces (Fa) applied to the joint will reduce the slip load. Accuracy. Tensioning sequence information. Finding Tension Loads on Fastener Group This procedure is similar to the shear load determination, except that the centroid of the fastener group may not be the geometric centroid. Pb = Bolt axial load resulting from yield, ultimate or joint separation load V = Bolt shear load resulting from limit load ... the calculation of the maximum and minimum preloads: (a) The maximum and minimum torques of the specified torque-range plus any prevailing torque (Tmax, Tmin and Tp).

This uses the equations from ANSI B1 1-1974 and B18.3.1-1978 which calculates the area carrying the tensile load from the mean of the pitch diameter and the minor diameter. Tensile Capacity at 195N/mm. Torque window, displays torque and defines coefficient of friction Load Graph window, displays bolt stress over a 3 stage time period BTS TAKES THE COMPLEXITY OUT OF BOLT TIGHTENING CALCULATION. After calculating the torque, ensure the bolts are not over-stretching and exceeding their yield strength, or some predetermined design stress. Higher or lower values of clamp load can be used depending on the application require- Selecting “Auto Spacer” from the Spacer drop down menu, allows the software to calculate a suitable spacer thick-ness based on a target Load Transfer Factor (Note the lowest LTF when using bolt tensioning tools is 1.15). 5) Calculate torsional shear force (Fm) The accuracy of all calculations performed in the shock load calculator is … As a reality check if we approximate to a cross sectional area of 7 mm 2 and a load of 1000 N that gives a tensile stress of 140 MPa which is below yield even for low tensile steels.. Thanks a lot for your clarifications. 2. The preferred bolt preload for structural applications should be at least 75% of the fastener's proof load for the higher strength fasteners and as high as 90% of the proof load for permanent fasteners. Calculation Basis SR1 Software calculates, in accordance with VDI 2230, high-stress bolted joints with concentric or eccentric strain and load. Values calculated using industry accepted formula T = KDP where T = Torque, K = torque coefficient (dimensionless), D = nominal diameter (inches), P = bolt clamp load, lb.
