Essay

The new modification of the dynamic stiffness method was developed for effective harmonic vibration analysis of multibranched spatial pipeline systems. In particular, the universal simulation method for curvilinear beams was designed. The analytical expression for a dynamic coefficient of bend flexibility was obtained, which allows to take into account an ovalization of the bend at vibrations, using relatively simple beam models. The computer program based on the developed methods was built.
