“…The FlowSimulation software product is used to evaluate thermal, aero and hydrodynamic processes [12]. It is fully integrated into the SolidWorks program, which is designed for solid-state parametric modeling and allows you to obtain models for aerohydrodynamic and thermal analysis [13,14]. A 3D model of the LNTD was created in the SolidWorks program (Figure 1).…”

Pollution of the environment, especially the marine environment, is currently a rather serious problem. The impact of noise on the fragile biota of the Arctic with an increase in shipping in this region is quite strong. The manufacture of new low-noise devices at an enterprise engaged in the creation of surface and underwater vessels is a very costly process. Computer simulation systems can reduce enterprise costs. The author proposes a system for complex modeling of low-noise devices that could predict the approximate behaviour of a viscous incompressible fluid (gas) in the form of vorticity per single object, described by Navier-Stokes differential equations for the case of fluid motion in a limited space. The system includes: a computer model in the well-established FlowSimulation system and a machine learning model. According to the results of the experimental study, the author found that the model from FlowSimulation has a clearer picture, but for FlowSimulation this is the limit of possibilities, and for the machine learning system there is the possibility of further development to improve the image. In the future, the author intends to continue experiments on training the model in order to obtain a better image.

A research challenge of vibration and control optimization of pressurized reducer is solved in this article; a method based on genetic algorithm (GA) is proposed to optimize the vibration and control of reducer. Considering the bending strength of helical gear root and tooth surface contact fatigue strength as constraints, the improved GA is used to solve it, and the optimal parameter combination is obtained. The size of center distance is reduced by 9.59% compared with that before. Based on the optimized results, the vibration becomes weaker with the increase of the load at the output end of the reducer, and its maximum value is only 1/8 of that when the load is 550 N. The experimental results show the optimized surface load distribution of driving gear teeth. The maximum normal load per unit length of the optimized output stage driving gear surface is 521.321 N/mm, which is significantly lower than the 662.455 N/mm before optimization. At the same time, the tooth surface load is evenly distributed. The larger tooth surface load is mainly distributed in the middle of the tooth surface with strong bearing capacity, which effectively solves the problem of unbalanced load before optimization and improves the bearing capacity of gear transmission. It is proved that GA can effectively realize the vibration and control optimization of pressurized reducer.
