The utility model relates to building structure technical field, specifically disclose a large-span steel wood truss structure for roof, include: end support block, it sets up in steel wood truss structure both ends, and is connected with building foundation structure, the end support block one side is arranged as the support of adapting with butt joint truss, and butt joint truss, standard truss and arc truss connection constitute truss main body structure, the support of end support block and the installation groove inlayed connection of butt joint truss one end. This large-span steel wood truss structure for roof, the inlayed connection cooperation structure of butt joint truss and end support block is filled with structure glue, utilizes the deformation adaptability of inlayed surface friction and glue, and the initial deformation difference of steel wood interface is buffered, and the node steel bar group of positioning frame one both sides is passed through the axial force transmission of the gripping force of steel bar and component, and positioning bolt one passes through radial constraint and limits lateral deformation, and the force flow interference is avoided by the staggered distribution of both, and stress concentration is reduced.

This invention relates to the field of hydrodynamic gas bearing technology, specifically to a radial hydrodynamic air bearing, a motor, and an air compressor. The radial hydrodynamic air bearing includes a bearing housing and an arch foil. The arch foil is mounted on the bearing housing and provides support for the rotor. The arch foil has two or more segments, arranged sequentially along the axial direction of the bearing housing, and each segment is detachable from the bearing housing. According to the technical solution of this invention, the arch foil segments are arranged in an array along the axial and circumferential directions of the bearing housing. Arch foil segments with different stiffnesses can be provided in the axial and circumferential directions as needed, achieving variable stiffness of the arch foil in both directions. This facilitates differentiated bearing pressure, coordinates arch foil deformation, and improves bearing performance. Furthermore, the detachable assembly method of the arch foil significantly reduces the assembly precision requirements of the bearing and the replacement cost in case of abnormal deformation. When the arch foil is damaged, only the damaged part needs to be replaced, eliminating the need for complete replacement, saving costs and extending the overall lifespan of the equipment.

This invention discloses a layered design method for snow surface overlay on ice-structured load-bearing structures, relating to the field of ice and snow engineering technology. The method includes the following steps: S1, determining the design constraints and performance indicators of the snow surface overlay based on target working conditions and environmental data; S2, obtaining the microstructural parameters of the snow material to be laid, including initial porosity, ice crystal size distribution, coordination number, and contact geometry. This invention establishes a cross-scale mechanical performance evolution model to accurately capture the microscopic mechanisms of ice crystal sintering, particle creep, and fatigue damage of snow material under long-term load and temperature, solving the problem of performance prediction deviations caused by the inability of existing macroscopic models to reflect microscopic evolution. By constructing a quantitative mapping relationship between microstructural parameters and macroscopic mechanical properties, combined with thermo-coupling load history simulation, accurate performance evolution data of the overlay can be obtained.
