Estimation of Dynamic Characteristics of Vibration Protection Systems of a New Type for Water Transport Vessels

Abstract

The use of traditional means of vibration isolation of ship power plants does not always give the desired effect, which predetermines the need to search for and use fundamentally new devices to improve the efficiency of vibration isolation of a ship engine. This can be achieved by installing active-passive vibration isolators in the elastic mounts of the engine, such as electromagnetic hydraulic vibration isolators (EHVO) for auxiliary engines and other marine equipment. Despite the seeming simplicity of the design and principle of operation, the calculation of EHVO is a rather complex problem, the solution of which is associated with a number of difficulties due to the specific features of electromagnetic devices, since their calculation is associated with a large number of factors and limitations. The known functions of time obtained by solving the equations were used to calculate the dynamic parameters of the EHVO: vibration energy, periodicity, overheating of the coils and efficiency
