Investigation Of A Pre Tensioned Bolt Analysis can be made of the burdens and strains created in a rush after various techniques for fixing, and permits displaying of the conduct of a catapulted association when pivotally stacked. Showing goals The mechanical assembly permits the accompanying analyses: Deformations in a rush in the wake of fixing with a spanner or with a torque. Impact of jolt pre-tensioning utilizing a pressure driven stacking framework. Impact of shifting the stacking position. Impact of changing the materials on the stacking torque. Static examination of sliding with grinding on a helical screw contact surface or plane. Basic stacking and weights on a plane area. Mohrs Circles of pressure, vital burdens and their headings. Specialized details The pre-stacked jolt gathering is made out of : A 16mm rush on which are settled three sets of oppositely contradicted 45° strain. These allow the estimation of augmentation and pressure in the jolt. A tubular segment with 2 strain checks mounted at 180° to gauge the pressure in the get together at various statures. A stacking tube to apply jolt pre-stack or to apply stacking power at different positions along the shot get together. A physically worked pressure driven pump. A micrometer dial check to quantify expansions over the total get together. Nuts and washers of different materials. Hardware Package : Pre-stacked jolt get together with pressure driven stacking framework and manual pump. An arrangement of washers. Specialized manual and educating notes. Measurements and weight 15 diam. x 37 cm – 12 kg Pump: 40 x 10 x 14 mm – 3,5kg Essential prerequisites Electrical supply : 220V, 50 Hz Additional required hardware : Extensometer connect. A ring spanner 24 mm. A torque of limit 40 – 200 Nm with 24 mm nut.
