Mech. VL - 38 IS - 1 SE - Research Article DO - 10.15625/0866-7136/38/1/5928 UR - https://vjs.ac.vn/index.php/vjmech/article/view/5928 SP - 15-25 AB - <p>This paper proposes a numerical procedure based on the well-known Newmark integration method to determine initial conditions for the periodic solution of a system of linear differential equations with time-periodic coefficients. Based on this, steady-state periodic vibrations of mechanisms with elastic elements governed by linearized differential equations with time-periodic coefficients can be conveniently calculated. The proposed procedure is demonstrated by a dynamic model of a planar four-bar mechanism with the flexible coupler.</p> ER -
