Abstract
The ship power propulsion system is the "heart" of the ship, and the ship propulsion shafting is the core unit of the ship power propulsion system, and it is an indispensable part of the ship's propulsion torque and thrust transmission. The operating status of the propulsion shafting directly affects the operating conditions of the ship, and even the life of the ship. Bearing load is one of the most important manifestations of the operating state of the propulsion shafting. Focusing on changes in the bearing load can better study the operating state of the propulsion shafting. The research on the steady-state load of ship propulsion shafting meets the needs of ship development and has great value for practical engineering applications. This paper takes the ship propulsion shafting-oil film-bearing structure system as the research object. Through the steady-state load mathematical model of ship propulsion shafting bearings, it reveals the coupling relationship among ship propulsion shafting bearing load, oil film force, and journal position, and establishes the ship The steady-state load calculation method of the propulsion shafting bearings solves the basic theoretical problems of modeling and analysis of the steady-state operating state of the ship's propulsion shafting, and provides theoretical support for the safety prediction, management and evaluation of the ship's propulsion shafting operation.

The operation of the shipbuilding industry from January to July 2019 issued by the China Shipbuilding Industry Association shows that my country's shipbuilding industry has made considerable progress, and the three major shipbuilding indicators are second only to In Japan, it is a veritable shipbuilding country
Ships are the main means of transportation in the shipping industry, and the performance of ships directly affects the development of the shipping industry; as the heart of the ship, its importance is self-evident
Summary
On May 16, 2019, the Ministry of Transport, together with the Central Cyberspace Administration of China, the National Development and Reform Commission, the Ministry of Education, the Ministry of Science and Technology, the Ministry of Industry and Information Technology, and the Ministry of Finance, issued the "Guiding Opinions on the Development of Smart Shipping", marking the future of smart shipping 30 Year development points out the direction. The shipbuilding industry is a modern comprehensive and strategic industry that provides technical equipment for water transportation, marine resource development, and national defense construction. It is an important part of the country's development of high-end equipment manufacturing, and it is the foundation and important support for the country to implement its maritime power strategy. My country's shipbuilding industry has achieved rapid development, it is still not a strong shipbuilding country It is still a long way from Japan and South Korea in terms of quality and efficiency. Ship propulsion shafting is very important for the normal operation of the ship, and related to the safety of the ship’s personnel and property and marine environmental protection issues. It is of great research significance to carry out research on the operating state of the ship's propulsion shafting, and it is of guiding significance to ship owners, shipyards and ship operators
