The invention discloses a collision experiment device for a flexible rotor of a squeeze film damper. The collision experiment device comprises a bottom plate, a long shaft, a motor, a disc, a first bearing seat, a first bearing, a second bearing seat, a second bearing, a first acceleration sensor, a second acceleration sensor, a first displacement sensor, a second displacement sensor, a rotating speed sensor and a data processing system. According to the invention, accurate simulation and effective data acquisition can be carried out on nonlinear resonance and self-excited oscillation of the rotor, so that the dynamic characteristics of the rotor system in practical application can be better simulated in practical application.

The invention discloses a serial crystallography experiment device based on a chip technology and an assembling method thereof. The device comprises a chip, a chip base, a chip operation board, a chip lower disc, a chip upper disc and a low background scattering film, a plurality of hollow chip holes are formed in the chip and are used for supporting and adsorbing the crystal; the lower chip disc and the upper chip disc fix the low background scattering films at the upper end and the lower end of the chip base in a nesting manner; a liquid removal chamber groove and a liquid removal chamber are arranged on the chip operation board and are used for removing redundant crystal solution in the chip; the groove of the liquid removal chamber is used for accommodating a chip base, an air exhaust hole is formed in the side wall of the liquid removal chamber and connected with an air exhaust pipe of an air exhaust system, and acting force is generated on the crystal solution to enable the redundant crystal solution to be sucked to the other end of a chip hole; and the chip operation board is provided with an observation chamber groove and an observation chamber and is used for observing the state of the crystal in the chip hole. According to the invention, the chip can be rapidly assisted to remove redundant crystal solution, and the chip can be rapidly observed, assembled and installed on a line station.

The utility model relates to the technical field of geophysical exploration, and discloses a novel electrode for geophysical exploration, which comprises a hammering head, an electrode stem and a conical tip, the electrode stem is made of brass, two ends of the electrode stem are respectively in threaded connection with the hammering head and the conical tip, and the hammering head and the conical tip are made of steel. According to the electrode designed by the utility model, the hammering head made of steel is arranged at the upper part, and the conical tip made of steel is arranged at the lower part, so that the problems that the head part of the electrode is easy to hammer and the tail part is easy to bend are solved, and only the conical tip can be replaced after the conical tip is damaged and bent, so that the normal driving of the electrode can be ensured.

The multi-parameter integrated acquisition terminal provided in this application dynamically configures and adaptively adjusts the data acquisition tasks for the monitored object through the signal conditioning and acquisition module in collaboration with the local intelligent processing module, thereby improving the intelligence level of data acquisition by the terminal deployed at the local edge. Furthermore, based on the characteristics of the monitored device, it constructs fused features by calculating the correlation between primary features in the synchronous real-time data stream after task adjustment, rather than simply fusing individual primary features directly. This allows the fused feature vector and summary uploaded by the local intelligent processing module to be directly used by maintenance personnel, reducing the data analysis pressure on the backend monitoring system and further improving the intelligence level of data acquisition by edge devices.
