Embodiment Construction
[0021] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0022] refer to figure 1 , 2 , 4, the present invention has installed 7 vertical displacement sensors, 3 lateral displacement sensors, 2 longitudinal displacement sensors and rotating speed sensor 4, temperature sensor 6 between propulsion and power equipment large-scale vibration isolation device raft frame and hull. figure 2 Also have vibration isolator 11, base 12 in.
[0023] The vertical displacement sensor 1-7 and the lateral displacement sensor 2-3 of the present invention are installed near the shaft coupling 7, and are respectively used to provide the vertical and horizontal values of the raft required for the solution of the vertical offset and the horizontal offset. The direction reference displacement change information can effectively reduce the centering state calculation error caused by the elastic deformation of the raft str...
