Modelling and mesh generation of weld profile in tubular Y-joint

摘要

This paper describes a systematic method of modelling the weld thickness of a tubular y- joint. The intersection between the chord and the brace members is defined precisely. This intersection curve will then be used to evaluate the dihedral angle γ, which is the angle between the chord and the brace surfaces along the intersecting line. As the dihedral angle γ is an important parameter used to determine the weld thickness, its variation along the intersection curve an its relationship with the weld thickness is investigated first. important parameter used to determine the weld thickness, its variation along the intersection curve and its relationship with the weld tickness is invesigated first.
