Rotating machinery is widely used in the shipbuilding industry due to its small size and high efficiency.When it works,it is often installed on platforms such as the bottom plate and base to improve its load-bearing capacity and atten-uate the vibration and impact transmitted to the hull.The traditional design method often installs rotating mechanical e-quipment in the middle position of the bottom plate,without fully considering the impact of equipment installation method on vibration performance.Taking a certain marine air pump as the research object,the finite element method is used to an-alyze the vibration characteristics of different installation methods of the pump body.Based on Python language,a program for the structural design and response optimization of the rotating machinery installation platform is developed,and the re-liability analysis of the optimized installation method is carried out.The results show that compared to traditional installa-tion methods,the optimized layout scheme significantly reduces the vibration acceleration of the bottom plate while ensu-ring its bearing capacity,verifying the effectiveness of the optimized scheme for rotating machinery installation platform.
