Calculating clamping force from bolt torque
WebHow do I calculate torque? To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r). If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm. WebIn this case, it is necessary to determine the torque value necessary to achieve the desired preload force in the bolt. This torque is calculated using: T = K T d nom F PL where d nom is the nominal bolt diameter …

WebThe BOLTCALC program completes an analysis of a bolted joint by considering the forces acting upon a single bolt. The program will allow for variations in the bolt clamp force (or preload) due to the tightening method and embedding due to plastic deformation in the thread and under the nut. WebThe calculator below can be used to calculate the torque required to achieve a given axial bolt force or load. The calculator is generic an can used for imperial and metric units as …
WebValues calculated using industry accepted formula T = KDP where T = Torque, K = torque coefficient (dimensionless), D = nominal diameter (inches), P = bolt clamp load, lb. K … WebStep 1: The bolted joint is tightened to 5 kN.No external load is applied. Step 2: External static loads (4 kN ) are applied but less than the preload. The initial preload now becomes the residual preload. The bolt load is calculated to 5.4 kN but the clamp force is reduced down to 1.4 kN.
WebT = DFK. This formula expresses the relationship between the load in a bolt and applied torque. The “D” represents the bolt’s diameter, the “F” is the axial bolt force, and the “K” represents “k-factor” or “nut factor” which is … WebFastener Relation Between Bolt Torque and Clamping Force Formula and Calculator per.
