Research on mechanical strength of elliptic tenon and eccentric connection part of solid wood parts

ABSTRACT

In this paper, the influence of the thickness, width and mortise-fit parameters of the tenon on the pulling and bending strength of the tenon is studied by comparing the mechanical strength of the tenon with the eccentricity joint. The influence of the fit amount of the embedded nut and the aperture on the mechanical strength; Comparison of mechanical strength between elliptic tenon and eccentric joint. These aspects are studied and the following results are obtained.

Key words：Solid Wood Parts; Ellipse Tenon; Eccentric Connection Part; Mechanical Strength
