2results about How to "Reduce lateral stiffness" patented technology

The utility model discloses a composite assembled shear wall of arrangement distribution steel bar based on principal stress, its characterized in that, include: wall body and hidden column, wall body inside is provided with oblique direction steel bar, and oblique direction steel bar is along the arrangement of principal stress direction, and the wall body is filled with light thermal -insulated material, and hidden column sets up at the both sides of wall body, and the end of oblique direction steel bar extends out of wall body, and extends into hidden column, and is connected with the pouring of hidden column. The utility model discloses the shear wall can reduce lateral stiffness, improve the thermal -insulating, sound insulation effect.

The invention discloses a rigidity-adjustable buffer pad for a damping system of a compressor of a new energy commercial vehicle. An upper buffer pad is formed by vulcanizing an upper buffer pad stainless metal framework, a lower wear-resistant layer framework and a rubber body; the lower buffering cushion is formed by vulcanizing a lower buffering cushion stainless metal framework, a lower buffering cushion upper flanging framework and a rubber body, the upper flanging framework is embedded into the rubber body after being vulcanized, outer layer rubber coating is achieved, the product appearance is improved, and the anti-rust capacity of the frameworks is improved. The height size of the central pipe is 3 mm shorter than that of the cushion pads in a natural state after the cushion pads are assembled, the upper cushion pad, the lower cushion pad and the central pipe form a whole after the whole vehicle is assembled and tightened, the rubber body bears certain compression, and the fatigue life of the cushion pads is prolonged. The inner walls of the rubber bodies of the upper buffer cushion and the lower buffer cushion are arranged to be conical surfaces, and a gap of 1mm is formed between the inner walls and the outer circle of the central pipe, so that the central pipe is convenient to assemble, meanwhile, the transverse rigidity of the buffer cushions can be reduced, rigidity matching of a whole compressor vibration reduction system is integrally realized, and the NVH performance of a whole vehicle is improved.
