The invention discloses a height adjusting and controlling system for a ship airbag vibration isolator. The height adjusting and controlling system comprises a compressor, a pair of airbag vibration isolator groups, a pair of inflating / deflating mechanisms, a pair of displacement sensors, and a controller, wherein the airbag vibration isolator groups are respectively located on two sides under a ship propulsion system; the input ends of the inflating / deflating mechanisms are respectively connected with the output end of the compressor, and the output ends of the inflating / deflating mechanisms are correspondingly connected with the input ends of the pair of the airbag vibration isolator sets; the displacement sensors and the airbag vibration isolator sets are correspondingly arranged; and the controller is in circuit connection with the displacement sensors and the inflating / deflating mechanisms, monitors the position states of the pair of airbag vibration isolator sets based on detection data of the displacement sensors and controls the pair of inflating / deflating mechanisms to be inflated / deflated, so as to achieve height adjustment for mass centers of the airbag vibration isolators. The height adjusting and controlling system disclosed by the invention has the advantages that power demands for air compressors of the air bag vibration isolators by the large ship propulsion system can be reduced and the stability in the height adjustment of airbag vibration isolation devices can be improved through a step-by-step height adjustment method.
Description
technical field [0001] The invention relates to the technical field of adjustment of a ship's airbag vibration isolation device, in particular to a height adjustment control system and method for a ship's airbag vibration isolation device. Background technique [0002] The airbag vibration isolation device can effectively attenuate the transmission of the vibration of the ship's propulsion system to the main body of the ship, and has a good application prospect. Due to the large mass of the ship's propulsion system and the limited installation space of the vibration isolator, the airbag vibration isolator for ships has the characteristics of small structural size, high bladder strength and high working pressure. Therefore, the ship airbag vibration isolation device requires a very large power of the air compressor in the attitude position control process such as height adjustment, which easily affects the compact design and cost control of the ship airbag vibration isolation...
