Move downward, with this come simulate drill ship wave effect under heave movement.
The working principle of compensation of undulation experimental provision 100 provided in this embodiment is described in detail below.
Before carrying out compensation of undulation experiment, the preparation of the compensation of undulation experimental provision 100 need to be first completed, i.e., will
Platform oil cylinder, passive oil cylinder and the actuating cylinder 11 are connect by corresponding hydraulic fluid port with the fueller, and will also
The passive oil cylinder is connect by corresponding hydraulic fluid port with the accumulator apparatus, in addition, the fueller is also connected by hydraulic fluid port
The accumulator apparatus is connect, and is electrically connected with the control device.It is described flat that the control device, which controls the fueller,
Platform oil cylinder, the passive oil cylinder and the actuating cylinder 11 are oil-filled, so that the piston of above-mentioned oil cylinder is respectively positioned on the centre of stroke
Position forms initial oil gas pressure balance.
When carrying out compensation of undulation experiment, on the one hand, when the control device controls the fueller to the platform oil
Cylinder is oil-filled, and when so that the piston rod of the platform oil cylinder driving the platform framework 4 to move upwards, the platform framework 4 is driven
The hook 7 instantaneously moves upwards, and then the simulation drill string 9 instantaneously moves upwards, and the simulation drill string 9 is to the spring
101 pressure reduction, the pressure data that the pressure gauge 102 feeds back to the control device reduces, due on the hook 7
It rises, the hook 7 pulling force upward to the simulation drill string 9 increases, thus the hook 7 is to the piston rod of the passive oil cylinder
Downward pressure increases, and the upper and lower ends of the piston of the passive oil cylinder will generate pressure difference, i.e. disequilibrium, thus the quilt
Piston moves downward for dynamic oil cylinder, i.e., its piston rod moves downward, to drive the hook 7 to move downward, described in compensation
The upward displacement that hook 7 generates due to the platform framework 4 moves upwards, also, the passive in-oil cylinder hydraulic oil quilt
It is pressed into the accumulator apparatus, forms new oil-air pressure balance；At the same time, the control device is according to the platform
The number pressure that the range data and the pressure gauge 102 of position sensor 12 and the hook position sensor 13 feedback are fed back
According to, control the fueller be the active hydraulic cylinder rodless cavity it is oil-filled so that the piston of the active hydraulic cylinder
Bar moves downward, to be further compensate for the upward displacement that the hook 7 generates due to the platform framework 4 moves upwards.It is comprehensive
On, when the piston rod of the platform oil cylinder drives the platform framework 4 to move upwards, the piston rod by hydraulic cylinder
It is moved downward with the piston rod of the active hydraulic cylinder, to compensate the hook 7 due to the platform framework 4 moves upwards
The upward displacement generated, and the simulation drill string 9 returns in preset pressure limit the pressure of the spring 101.
On the other hand, when the control device control fueller is oil-filled to the platform oil cylinder, so that described flat
When the piston rod of platform oil cylinder drives the platform framework 4 to move downward, the platform framework 4 drives the hook 7 instantaneous downwards
Movement, and then 9 momentary downward movement of simulation drill string, the drill string 9 of simulating are described to the pressure increase of the spring 101
The pressure data that pressure gauge 102 feeds back to the control device increases, and since the hook 7 declines, the hook 7 is to the mould
The upward pulling force of quasi- drill string 9 reduces, thus the pressure reduction that the hook 7 is downward to the piston rod of the passive oil cylinder, described
The upper and lower ends of the piston of passive oil cylinder will generate pressure difference, i.e. disequilibrium, so that the piston of the passive oil cylinder is transported upwards
Dynamic, i.e., its piston rod moves upwards, to drive the hook 7 to move upwards, to compensate the hook 7 because of the platform framework
4 move downward and the downward displacement that generates, also, the hydraulic oil in the accumulator apparatus is pressed into the passive oil cylinder
In, form new oil-air pressure balance；At the same time, the control device is according to the platform position sensor 12 and described big
The pressure data that the range data and the pressure gauge 102 that hook position sensor 13 is fed back are fed back, controls the fueller
Rod chamber for the active hydraulic cylinder is oil-filled, so that the piston rod of the active hydraulic cylinder moves upwards, with further
Compensate the downward displacement that the hook 7 generates due to the platform framework 4 moves downward.To sum up, when the platform oil cylinder
It is described by the piston rod of hydraulic cylinder and the active hydraulic cylinder when piston rod drives the platform framework 4 to move downward
Piston rod move upwards, to compensate the downward displacement that the hook 7 generates due to the platform framework 4 moves downward,
And the simulation drill string 9 is returned in preset pressure limit to the pressure of the spring 101.
It can be seen that the compensation of undulation experimental provision can be examined according to the pressure data that the pressure gauge 102 is fed back
Whether the control algolithm in 100 structure design and the control device is reasonable.
