Viscoelastic damping truss vibration isolator

Номер: CN104879414A
Автор: DING SHITAO, XIAO DAZHOU, MA JUN, CAI WEIJUN, LI MING, CHEN FANG
Принадлежит:

A viscoelastic damping truss vibration isolator comprises an upper mounting seat (1), spherical gaskets (2), a spring (3), a spherical base (4), an inner barrel (5), an outer barrel (6), a damping adhesive layer (7), a limit bolt (8), a limit retainer ring (9), a limit nut (10), an end cap (11) and a lower mounting seat (12). The inner barrel (5) and the outer barrel (6) are separated and injected with damping adhesive and are allowed to displace relatively, the relative displacement of the inner barrel (5) and the outer barrel (6) is limited within the reasonable range by the limit bolt (8), and supporting and vibration isolating of a damping truss are realized. Compared with the prior art, the viscoelastic damping truss vibration isolator has the advantages that buffer is realized by deformation of the spring (3) and the damping adhesive layer (7), vibration coupling is effectively avoided, and influence on the truss supporting structure from vibration is reduced. Meanwhile, the viscoelastic ...

The invention discloses a method for repairing pipelines and a repair material system thereof. The combined material system used for the repair and reinforcement of the pipelines provided by the invention consists of a healant for filling and leveling up the flaws, an anti-negative pole peeling coating, carbon cloth and impregnant rubber. The pressurization test proves that the pipelines repaired by adopting the method and the combined material system of the invention can restore or improve the loading capacity of the pipelines, thereby achieving the loading design standard of the pipelines. The combined material system not only plays the role of repairing and reinforcing the flaws, but also effectively avoids the occurrence of various electrochemical corrosion problems of the flaws. The combined material repair system has easy and practicable repair method and high operability in the process of the repair and reinforcement of the pipelines. The repair material system and the repair technology ...

The invention relates to an ultra-wide free-form surface off-axis double-reflector telescopic system, which comprises a first reflector, an aperture diaphragm, a second reflector and an image surface, target incident light firstly passes through the first reflecting mirror and is gathered at the aperture diaphragm, and then is imaged at the image surface through the second reflecting mirror. The aperture diaphragm is located at the front focus position of the second reflector, so that the telescopic system is an image space telecentric system, and the grating beam splitting system with a slit is placed at an image plane to facilitate pupil matching. The first reflecting mirror and the second reflecting mirror have different radiuses, adopt free-form surfaces and are used for carrying out aberration correction on a full view field to realize high-quality imaging. The telescope system is an off-axis system and adopts off-axis design, and a certain included angle is formed between the first ...

Multifunctional composite slit for space spectrometer

Номер: CN116222771A
Автор: XIAO DAZHOU, WANG LIKE, AN NING, LI BICEN, ZHANG JIAMING, WANG WEIGANG, XU PENGMEI
Принадлежит:

The invention provides a multifunctional composite slit device for a space spectrometer, which is characterized in that two glass cuboids are respectively mounted on a support frame, one glass cuboid is provided with an optical reflecting surface, and straight edges of the two glass cuboids jointly form a composite optical slit through the mounting position; the straight edge is used as a working edge and is formed by intersecting two adjacent planes of the glass cuboid; the composite optical slit is used for realizing a slit function, field-of-view light splitting and light path reflex of the two detection channels are realized, the light path of one detection channel continues to propagate forwards through the optical slit, and the light path of the other detection channel is reflex to a specified direction through a reflection area of one of the glass cuboids. And a relay lens is mounted on the supporting frame in the specified direction.
