In marine diesel engine, main bearing bolts (M18×1.5) withstand large tensile and cyclic loads to keep the crank shaft, bearing whit acceptable clearance and precision clamping force at high crank speed like 3100 rpm. In this research, the relationship between torque and clamp force, the friction coefficient, the effect of number of tightening and bearing conditions on the new manufactured bolt...

This paper examines the dowel-bearing strength of laminated flattened-bamboo lumber (LFBL) perpendicular to grain under influence arrangement method, bolt diameter, and specimen size in accordance with ASTM D5764-97a. There were 360 specimens tested total. As a result test results, it was demonstrated that method flattened bamboo panels significantly affected LFBL. In two groups (bolt direction...

This study investigates the shear capacity of aluminum alloy honeycomb sandwich plates connected by high-strength, ordinary, or self-tapping bolts. For that purpose, experimental tests and finite elements are carried out. The failure of a high-strength bolt connector is driven by bending deformations developed in the bolt that deform connection plate and pad openings. In the case of ordinary bo...

An experimental study is presented on the effects of bolt-hole clearance on the load distribution in multi-bolt composite joints. Single-shear, three-bolt joints were studied. The specimens were manufactured from graphite/epoxy HTA/6376, with quasi-isotropic lay-ups. Protruding head bolts of 8 mm diameter and torqued to finger-tight conditions were used. Different combinations of clearance were...

In this work, the effect of rock bolt angle on the shear behavior of Rock Bridges is investigated using the particle flow code in two dimensions (PFC2D) for three different Rock Bridge lengths. Firstly, the calibration of PF2D is performed to reproduce the gypsum sample. Then the numerical models with the dimensions of 100 mm * 100 mm are prepared. The Rock Bridge is created in the middle of th...
