To solve bolting groups in general: 1) Find the bolt group centroid 2) Determine directional vectors for each bolt with distance Rn 3) Calculate direct shear load for both the weight and applied load (Fv) 4) Calculate Reaction Moment (M) at the bolt group centroid. To achieve the benefits of the preloading, the clamping force must be higher than the joint separation load. The accuracy of all calculations performed in the shock load calculator is … Values calculated using industry accepted formula T = KDP where T = Torque, K = torque coefficient (dimensionless), D = nominal diameter (inches), P = bolt clamp load, lb. Thanks a lot for your clarifications. Load Calculator Quickly find the tensile, yield, proof, and estimated shear strengths of your bolts. Force = Bolt Load = ? Gross Area. Bolt Load Capacity Tables To BS5950 Part 1. By over-tightening the bolt, one may exceed the proof load of the bolt. Note: tensile axial forces (Fa) applied to the joint will reduce the slip load. BoltUP - Our online bolt load calculator; Informate - Our advanced calculation and procedure software; IDMS Integrity Data Management System - The complete package for managing Bolted Joints from cradle to grave. 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). Features the Indikon product line of legacy torque and vibration measuring devices. RE: ASME flange calculations design bolt load Vs. applied bolt load … Date :-01.01.2003. of threaded section of each bolt size. Calculation Basis SR1 Software calculates, in accordance with VDI 2230, high-stress bolted joints with concentric or eccentric strain and load. Accuracy of Bolt Preload Based on Bolt … Bearing strength of bolts. 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. Clamp load (lb.) Single. Open --> Bolt Preload Tension Force Calculator. Name * First. The load will vary for each bolt. EZ Calc - Bolting Calculator, Enerteq's oline tool for estimating Required Torque Values. Metric bolt grades and strength calculator to show proof strength, tensile strength, Vickers / Brinell hardness, minimum breaking torque and stress area of metric bolts and screws made of carbon steel and alloy steel with designations 4.6, 4.8, 5.8, 8.8, 9.8, 10.9 and 12.9. Product Lines. the bolt load is transferred from the Tensioner to the joints hexagon or round nuts. F t,Ed is the applied tensile load and F t,Rd is the tension resistance of the bolt. 2. Bolt Load Calculation Software Hydratight introduces Informate: the next generation of software that provides bolt loads and tool pressures on a huge range of flanged joints and clamped connections. Both lateral (single and double shear) and withdrawal capacities can be determined. Learn More. Explore the possibilities. Bolt Load Calculator Please note that the above data is based on bolts lubricated to manufacturer’s spec. K – constant d – diameter of bolt (m, in) F – axial bolt force or load (N, lb) In the continuation, the paper briefly presents the model for operating bolt load calculation and the method for the calculation of structure elasticity and stiffness matrices and presents a comparative analysis of the results obtained through different calculations and measurements. We provide it as a resource for our customers, because the weight of a bolt or assembly is often needed when calculating shipping costs, or jobsite delivery requirements. 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 . Caution. A material must remain in its elastic region when loaded up to its proof load typically between 85-95% of the yield strength. 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.. 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. To download BoltUp, or for a free 7 day trial of the Informate bolt load calculation software go to: joint-integrity.com. Bolt Load Calculator. The Calculators below can be to calculate the ultimate (breaking) load of bolts. Definition of the algorithm See also this calculator and this table. is calculated by arbitrarily assuming usable bolt strength is 75% of bolt proof load (psi) times tensile stress area (sq. Proof load is defined as the maximum tensile force that can be applied to a bolt that will not result in plastic deformation. pressure wax as supplied on high strength nuts) = .10, hot dip galvanized = .25, and plain non-plated bolts … If you're looking for the next big thing, FUTEK has a library of over 100 new and innovative ideas to incorporate its load cells, force transducer, torque sensors, pressure sensors, and multi-axis sensors. Actually what I do not understand in ASME is that the bolt load used for design seems different from the true bolt load (as the one I describe just above). Email * Website. 5) Calculate torsional shear force (Fm) 1) Enter thread diameter nominal value in section Thread Size.Click on info button for more info. Tensioning sequence information.
