Abstract

It was examined experimental complex joint effect of fit radial tension and tightening on the bolted joint durability under the fatigue test/ It was determined the friction force effect along hole side on the cycle number up to samples failure and joint failure nature change depending on the value of joint pressing under the assembly. It was estimated the possibility of joint durability increase under the additional joint pressing.
