Propulsion system is one of the dominant noise sources of naval vessels. Based on the Intelligent Air Spring Mounting technology which was applied to auxiliary machinery onboard ship, a new-type mount-ing system (NMS) for propulsion system is proposed. The dynamic model of air spring mounting system is presented. The factors that affect system stability and natural frequencies are analyzed, as well as the de-sign measures being devoloped. The monitoring model of alignment between propulsion plant and shafting is established, followed by the alignment control algorithm and rule which assures the quick and uniform con-vergence of alignment control process. Safety protection mechanism is designed to ensure that the propulsion system can operate safely in case of NMS failure or other severe circumstances. A scaled NMS prototype was manufactured and tested on a special experimental installation. Experimental results validate the effective-ness of theoretical models and show that the performance of NMS satisfies the requirements propulsion sys-tem. The NMS for propulsion system was applied in naval vessels.
