Transmission shafts vibrations in transient rotating modes

The paper presents the investigation results of transmission shaft dynamic behavior in transient modes motion with change rotational speeds. Such occur during transmits torque from engine to executive device. This process can be accompanied by vibration frequency and amplitude oscillation. Therefore, question studying such systems identifying impact speeds changing on them is relevant. In this regard, study was done developed software, which a technique computer simulation oscillating considerable rotating rods under action inertia forces implemented. software gives possibility model oscillatory determine parameters stability loss system occur. Using diagrams rod were drawn for definite considered system. oscillation space. mathematical transverse oscillations described differential equations coordinate that tied shaft, but shown inertial It when speed rotation changes, namely at time interval its increase, continues growth acceleration time. Also increases, too. After pass next constant rotation, oscillations, as diagrams, decreases back. increase lead undesirable consequences destructive nature.
