M16 (h=2mm, d1=13.54mm, d2=14.7mm) material quality 8.8 bolt-nut connection Blowout= 2500 daN prestress
bored with. Factor of safety S=2.5, key length L=10.d, coefficient of friction µo=
'=0.17; Average of contact surface with nut
diameter is given as d0=1.4.d. According to the given;
a) strength control calculation during tightening;
b) hand force that must be applied to the wrench
c) When the pre-tensioning force is applied, the elongation of the part is given as lp= 0.015mm, and the elongation of the bolt as lc= 0.030mm. Business
Since the total elongation of the bolt is lctop=0.040mm for Ftop=3000 daN after the force is applied, we can define the characteristic of the bolt.
find it.
d) the characteristic of the part and the minimum remaining shortening value önlp after the prestressing force
e) Calculate the portion of the operating force on the bolt (Fic) and the part (Fip).
f) Calculate the pre-tension force Fön' value remaining in the connection after the operating force has been applied.
