The propulsion shaft system is one of the main parts of the ship's power plant, and its working performance and stability directly affect the safety of the ship, and is also closely related to the life force and strength of the ship. In the environment of rapid development of science and technology, the working performance of the ship propulsion shaft system is becoming more and more demanding, and its components are becoming more and more complex. Therefore, the dynamic response characteristics of the shaft system need to be analyzed to meet the smooth working of the shaft system on the one hand, and to ensure the stability and impact resistance of the ship on the other hand. This paper is based on the traditional ship propulsion shaft system, the propulsion shaft system with universal coupling to modify, design a special transmission mechanism with adjustable tilt angle, firstly, use SOLIDWORKS to establish the propulsion shaft system model, and then import ANSYS for modal simulation analysis, get the first 100 order non-zero modal mass of the tiltable propulsion shaft system, and then simulate the acceleration of the tiltable propulsion shaft system under the action of impact The results show that the dynamic characteristics of the propulsion shaft system are complex and the modal vibration patterns are diverse during the ship navigation, and the tiltable propulsion shaft system can operate safely under the excitation of impact load.
