Abstract

With flexible usability, able to operate both on water and land, hovercraft has a long history of development and is widely used in many countries around the world. In this research, we focus on solving the problem of isolation oscillates when a machine - placed on an isolator - operates the pinwheel to create thrust momentum for hovercraft movements. The main content of the author’s master degree research is to study the oscillator system integrated in the engine structure to significantly reduce the vibration from the main engine and the propeller of the air cushion ship. The study focused on building a calculation model to find the main vibration characteristics of the propulsion system - motor - motor support structure integrated with damping system. Main objective is finding out the parameter values: transmission characteristics, specific frequencies of the air-cushion engine structure and damping system of supporting structure which are able to withstand the best vibration isolation. Based on reviewed literature, simulations and real-world tests (using CALFEM and following simulation models) are being performed to determine the optimal technology parameters. The findings and results continue to contribute to the improvement of engine technology in particular and seaplane engineering technology in general as required by standards and regulations.
