The operation principle of the compensation of undulation experimental provision 100 for providing the present embodiment below is described in detail.
Before compensation of undulation experiment is carried out, the preparation of the compensation of undulation experimental provision 100 need to be first completed, will Platform oil cylinder, passive oil cylinder and the actuating cylinder 11 are connected by corresponding hydraulic fluid port with the fueller, and will also The passive oil cylinder is connected by corresponding hydraulic fluid port with the accumulator apparatus, in addition, the fueller is also connected by hydraulic fluid port The accumulator apparatus are connect, and is electrically connected with the control device.The control device controls the fueller to be put down for described 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 give platform oil Cylinder is oil-filled so that when the piston rod of the platform oil cylinder drives the platform framework 4 to move upwards, the platform framework 4 drives The instantaneous motion upwards of the hook 7, and then the instantaneous motion upwards of the simulation drill string 9, described simulation 9 pairs of springs of drill string 101 pressure reduction, the pressure data that the pressure gauge 102 feeds back to the control device reduces, due on the hook 7 The piston rod of liter, the upward pulling force increase of the simulation drill string 9 of the hook 7 pairs, thus the passive oil cylinder of the hook 7 pairs Downward pressure increase, the upper and lower ends of the piston of the passive oil cylinder will produce pressure differential, i.e. disequilibrium, so that the quilt The piston of dynamic oil cylinder is moved downward, i.e., its piston rod is moved downward, so that drive the hook 7 to move downward, it is described to compensate The upward displacement that hook 7 is produced because the platform framework 4 is moved 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 of the range data and the feedback of the pressure gauge 102 of position sensor 12 and the hook position sensor 13 feedback According to the rodless cavity for controlling the fueller to be the active hydraulic jack is oil-filled so that the piston of the active hydraulic jack Bar is moved downward, to be further compensate for the upward displacement that the hook 7 is produced because the platform framework 4 is moved 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 Piston rod with the active hydraulic jack is moved downward, so as to compensate the hook 7 because of the upward motion of the platform framework 4 The upward displacement for producing, and cause that the pressure of simulation 9 pairs of springs 101 of drill string is returned in default pressure limit.
On the other hand, when the control device controls the fueller 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 Motion, and then the simulation momentary downward movement of drill string 9, the pressure of 9 pairs of springs 101 of the simulation drill string increases, described Pressure gauge 102 feeds back to the pressure data increase of the control device, because the hook 7 declines, 7 pairs of moulds of the hook Intend the upward pulling force of drill string 9 to reduce, thus the downward pressure of piston rod of the passive oil cylinder of the hook 7 pairs reduces, it is described The upper and lower ends of the piston of passive oil cylinder will produce pressure differential, i.e. disequilibrium, so that the piston of the passive oil cylinder is transported upwards Dynamic, i.e., its piston rod is moved upwards, so that drive the hook 7 to move upwards, to compensate the hook 7 because of the platform framework The 4 downward displacements for moving downward and producing, also, 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 range data of the feedback of hook position sensor 13 and the pressure data of the feedback of the pressure gauge 102, control the fueller For the rod chamber of the active hydraulic jack is oil-filled so that the piston rod of the active hydraulic jack is moved upwards, with further Compensate the downward displacement that the hook 7 being moved downward and produced by the platform framework 4.To sum up, when the platform oil cylinder It is described by the piston rod of hydraulic cylinder and the active hydraulic jack when piston rod drives the platform framework 4 to move downward Piston rod move upwards, so as to compensate the downward displacement that the hook 7 being moved downward and produced by the platform framework 4, And cause that the pressure of simulation 9 pairs of springs 101 of drill string is returned in default pressure limit.
As can be seen here, the pressure data for being fed back according to the pressure gauge 102, you can the inspection compensation of undulation experimental provision Whether the control algolithm in 100 structure design and the control device is reasonable.
