Background
On ships in various fields of application, it is common to equip the ships with high-precision equipment that is very sensitive to shock disturbances. These devices are extremely sensitive to external shock disturbances due to their very high accuracy of operation or measurement. The disturbance of the instrument in the direction of the vessel's shake is particularly acute due to the nature of the vessel's operation. This violent shaking can have a significant effect on the performance of the instrument, even in operation.
At present, two methods are mainly used for shock absorption of precision instruments: a passive vibration isolation device is adopted, and a spring and a damper are applied to isolate the influence of the vibration of a ship body on an instrument; adopt the vibration isolation revolving stage based on parallel mechanism.
As shown in fig. 1, the vibration isolation device using a spring and a damper can only reduce external vibration interference of a certain frequency or more due to the limitation of its operation principle, and theoretically cannot eliminate all external vibration influences. Thus, the external interference elimination effect on low frequency is poor; in addition, after the external vibration disappears, the system has residual vibration due to the characteristic of underdamping of the spring vibration isolation system.
As shown in fig. 2, in order to adopt the vibration isolation turntable based on the parallel mechanism, since 6 or more link mechanisms are required to shield the external vibration of the supported object, the control manner is complicated; in addition, because the driving force of the linear motor is small, a hydraulic connecting rod is required to be adopted for large-scale equipment, and the high-frequency vibration isolation response of the system is poor.

The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Referring to fig. 3 and 4, fig. 3 and 4 are two schematic structural views of a shock absorbing platform according to an embodiment of the present invention, in which the shock absorbing platform 100 is disposed on a deck of a ship and used for placing a precision instrument 200 on the ship to prevent the precision instrument 200 from being affected by external vibration. As shown in fig. 3, the vibration isolation platform 100 includes a passive vibration isolation device 1 disposed on a deck of a ship, a flywheel vibration isolation device 2 connected to the passive vibration isolation device 1, and a control system 3 electrically connected to the passive vibration isolation device 1 and the flywheel vibration isolation device 2.
The passive vibration isolation device 1 is arranged on a deck of a ship, and the passive vibration isolation device 1 comprises a supporting table 11, a plurality of vibration isolators 12 uniformly arranged on one side of the supporting table 11, and dampers 13 connected with the vibration isolators 12 in series one by one. Preferably, the vibration isolator 12 comprises an air spring or a steel spring. Flywheel damping device 2 is including supporting precision instrument 200's box 21 and locating at least three flywheel 22 in the box 21, box 21 is fixed in on the brace table 11, the shell of flywheel 22 with the inner wall butt of box 21 is fixed, and three the center pin of flywheel 22 is all unparallel, so that it is three flywheel 22 decouples along three direction along the rotation torque of rotation axis (center pin). The control system 3 comprises a plurality of sensors and a controller electrically connected with the sensors, and the controller is electrically connected with the flywheel. The sensors are respectively arranged on one side of the passive vibration isolation device 1, which is in contact with a ship deck, and are used for detecting a first sensing signal of external vibration; and the second sensing signal detection device is also arranged at the joint of the passive vibration isolation device 1 and the flywheel damping device 2, namely the joint of the box body and the support platform 11, and is used for detecting a second driving sensing signal entering the flywheel damping device 2 after being subjected to vibration isolation through the passive vibration isolation device 1. Preferably, the central axes of three of the flywheels 22 intersect at a point. Preferably, the central shafts of the three flywheels 22 are arranged vertically in pairs, so that decoupling is facilitated, and control and calculation of the platform are facilitated.
In the flywheel damping device 2 of the present invention, when the motor in the flywheel 22 performs acceleration and deceleration movement on the rotating flywheel, the flywheel stator and the housing need to apply a moment to the flywheel, according to the third law of newton, the flywheel housing must simultaneously bear a moment in the opposite direction, and the moment must be borne by the passive vibration isolation device 1 connected with the flywheel damping device 2. Therefore, by accelerating and decelerating the flywheel 22, the system can generate a corresponding controllable torque in the direction of the rotation axis (i.e. the central axis) of the flywheel 22 by using the principle to counteract the influence of the driving torque on the precision instrument 200 in the direction after passing through the passive vibration isolation device 1. Since the vibrations of the precision instrument 200 are caused by external forces and torques, maintaining zero rotation of the platform in this axial direction keeps the precision instrument 200 stationary in this axial direction. Since there are three directions for the external shaking vibrations, the system provides three flywheels 22 to meet the vibration isolation requirements on the three angular axes. The flywheel damping device 2 is matched with the passive vibration isolation device 1 for use, so that the bandwidth limitation of the passive vibration isolation device 1 can be completely eliminated, the swing of the precision instrument 200 is completely eliminated, and meanwhile, the linear vibration is greatly weakened.
According to the damping platform 100, firstly, vibration on a ship is damped for the first time through the passive vibration isolation device 1, external vibration interference above a certain frequency can be weakened, and then the weakened transmission and the vibration with lower frequency are damped through the flywheel damping device 2 so as to offset the influence of all external vibration. The damping effect of the flywheel damping device 2 in the damping platform 100 is mainly determined by the torque of the motors in the three flywheels 22, and the torque of the motors completely depends on the driving design of the motors and the driving design of the motors, so that the motors can be changed in size and freely.
In an optional embodiment, in order to facilitate the decoupling of the shaking vibration control and the linear vibration, the angle pose of the passive vibration isolation device 1 is completely controlled by the flywheel, and the angle pose can be controlled outside the vibration isolation function, that is, the pitching angle of the precision instrument 200 can be precisely driven to move. The base of the box 21 close to the supporting table 11 in the flywheel damping device 2 is connected with the supporting table 11 in the passive vibration isolation device 1 in a ball hinge manner, and with reference to fig. 3, the base 211 of the box 21 close to the supporting table 11 is a cone, the conical top 212 of the cone is processed into a sphere, and the supporting table 11 is provided with a hinge shaft seat 213 hinged with the conical top 212, so that the flywheel damping device 2 is hinged with the passive vibration isolation device 1.
In an alternative embodiment, in consideration of cost control, the spherical hinge structure shown in fig. 3 may be simplified to process the contact point between the flywheel damping device 2 and the passive vibration isolation device 1 into a spherical surface shape, and in particular, referring to fig. 4, the base 211 of the box 21 may be processed into a spherical surface, and the spherical surface 211 is abutted and fixed to the support table 11, so that the installation and maintenance costs of the damping platform 100 may be greatly reduced on the premise of ensuring the damping performance of the damping platform 100. Preferably, the central axes of the three flywheels 22 pass through the spherical center of the spherical surface.
Based on the damping platform 100, the invention also provides a damping method for the ship precision instrument, which specifically comprises the following steps:
step S1, collecting a first sensing signal of the passive vibration isolation device 1 which is vibrated by a ship deck;
step S2, controlling the passive vibration isolation device 1 according to the first sensing signal;
step S3, collecting a second sensing signal which passes through the passive vibration isolation device 1 and then enters the flywheel damping device 2;
and step S4, controlling the rotation speed of at least three flywheels 22 according to the second sensing signal.
According to the damping method of the precision instrument 200 on the ship deck, the passive vibration isolation device 1 is controlled to carry out vibration isolation through the first sensing signal of the vibration of the ship deck, the second sensing signal of the transmission after the vibration isolation is collected, the rotating speed of at least three flywheels 22 is controlled, and then the reaction force of the at least three flywheels 22 on the passive vibration isolation device 1 connected with the flywheel damping device 2 is regulated and controlled, and the reaction force is offset with the transmission force of the passive vibration isolation device 1 after the vibration isolation. Because the invention utilizes the action torque generated by the flywheel to the outside when accelerating and decelerating, the control bandwidth of the flywheel to the external vibration barrier completely depends on the bandwidths of the rotating motor and the control system thereof, and the flywheel has excellent performance in low frequency, medium frequency and high frequency. Meanwhile, the torque of the motor in the flywheel completely depends on the motor and the driving design thereof, the size of the motor can be changed freely, and the vibration isolation capability has strong adaptability to photoetching machines with different sizes and grades.
The above examples only express preferred embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
