Abstract

A design of bolted joints with gaskets almost depends on experience and a sealing performance is not made clear by theoretical analyses. In the present paper, discussion is made on the distribution of contact stresses when a clamped part with a gasket or a filler plate is fastened with two tap bolts to a base which is large enough comparing with the clamped part. The distribution of contact stresses is analyzed as a three body contact problem using the two-dimensional theory of elasticity. Moreover, the contact stress is measured by means of ultrasonic waves. Next, the force ratio (a ratio of an increment of bolt axial force to a load) and the maximum stress caused in bolts taking a bending moment into account are analyzed. For verification, experiments are carried out. The analytical results are in fairly good agreement with the experimental ones.
