Abstract
The utility model discloses a balance monitoring mechanism for a centrifuge used in a stable state acceleration test. The balance monitoring mechanism includes two connecting pieces, a bearing plate and a plurality of pressure transducers. The two connecting pieces are installed in a cavity of a centrifuge rotating arm. Each connecting piece is internally provided with a pin shaft. The central axes of the two pin shafts are superposed and the long edges of the centrifuge rotating arm are vertical to each other. The two connecting pieces are connected with a transmission piece of a centrifuge through the pin shafts respectively. The bearing plate is arranged at the lower end of the transmission piece of the centrifuge. The upper surface of the bearing plate is vertical to the central axis of the transmission piece of the centrifuge. The plural pressure sensors are arranged on the bearing plates, and the sensing ends of the plural pressure sensors are contacted with the lower surface of the centrifuge rotating arm. The balance monitoring mechanism for the centrifuge used in the stable state acceleration test changes monitoring on centrifugal forces at two ends of a rotating arm into monitoring on static moments at two ends of the rotating arm, and thus the balance monitoring mechanism is effectively simplified.
Description
Technical field
The utility model relates to a kind of steady state acceleration test hydro-extractor mechanism for monitoring, relates in particular to hydro-extractor balance monitoring mechanism for a kind of steady state acceleration test.
Background technology
Stable state acceleration simulation has become one of requisite environmental simulation technology in field such as Aero-Space, Geotechnical Engineering and electric and electronic product environmental test, but direct physical is approximate or for the prototype system subsequent analysis, steady state acceleration test also can be used as effective means of supplementing out economy of conventional design and analytical technology, is widely used in scientific research and engineering practice.
Pivoted arm (truss-frame structure) formula hydro-extractor is as realizing the most frequently used equipment of stable state acceleration simulation technology, the centrifugal force that when effectively monitoring and opertaing device move, the pivoted arm two ends produce, to eliminate the impact of out-of-balance force on main frame, the use safety of assurance equipment, be one of emphasis of Design of Centrifuge, so the practicable balance monitoring of development and design mechanism tool is of great significance always.
The balance monitoring mechanism that current domestic pivoted arm hydro-extractor uses can be divided into following two kinds by principle of work and arrangement: a kind of mode is to make pivoted arm or workbench can produce the horizontal shift deviator with respect to centrifuge principal axis under the effect of centrifugal force by the linear slide pair, balance monitoring mechanism (containing force cell) is arranged to the linear slide parafacies between two parts of motion and pretension simultaneously, thereby directly monitors the centrifugal force that the pivoted arm two ends produce; Another kind of mode is near balance monitoring mechanism is symmetricly set in to main frame installation fulcrum along centrifuge principal axis, upsetting moment main frame produced by monitoring centrifugal force, the centrifugal force that indirect monitoring pivoted arm two ends produce.
Adopt the directly mode of monitoring centrifugal force, need to be secondary reserved the installation and inspection platform of linear slide in structural design, causes hydro-extractor region of interest complex structure, and the corresponding increase due to processing capacity and man-hour, promoted manufacturing cost; Adopt the mode of indirect monitoring centrifugal force, need to make main frame in the approximate state suspended by fulcrum is installed, to the Horizontal limiting of main frame, selecting of fastening means when main frame is in place and securing member special material all has strict demand, improve manufacture difficulty, thereby increased manufacturing cost.
The utility model content
