Description
technical field [0001] The invention relates to a vibration isolation device, in particular to a vibration isolation simulation device for auxiliary equipment in a ship's engine room. Background technique [0002] Vibration and noise is one of the main performance parameters of ships, and engine room power equipment is the main source of ship vibration and noise. With the rapid development of shipbuilding technology, vibration and noise reduction technology has attracted more and more attention. [0003] There are many types and quantities of power equipment in the engine room, and various power equipment are arranged inside the engine room according to certain requirements to realize the overall function of the engine room. Due to the different working principles of various power equipment in the engine room, there are differences in the characteristics of vibration and noise sources, and the vibration isolation measures taken for them are also different. Due to the compac...
