Method for Controlling Vibration Processes in a Vibration Protection System

Abstract

Among the requirements for vibration isolation, the most important is the requirement for the range of natural vibration frequencies. We study the suspension of a marine engine on elastic pneumohydraulic vibration-isolating mounts (PVIM) as the most promising vibration protection systems of the new generation. A method for calculating the natural vibrations of spatial vibration-isolated objects is presented. An algorithm is presented for reducing vibration frequencies to a narrow range by varying the coordinates and installation angles of such vibration isolators as air defense. An example of calculation is given.
