摘要: In this paper, a numerical method for solution of the free vibration beams governed by set second-order ordinary differential equations variable coefficients, with arbitrary boundary conditions, is presented. The based on integration rather than differentiation since highest derivatives governing functions are chosen as basic unknown quantities. kernelsof integral turn out to be Green's function corresponding equation homogeneous conditions. accuracy proposed demonstrated comparing calculated results those available in literature. It shown that good can obtained even relatively small number nodes.
