Detailed Description
The novel triangular array frame structure butt joint method related by the invention is explained in detail with reference to the accompanying drawings 5-10:
a triangular array frame supporting structure of a dome radar is provided, adjacent rims 3 are connected at a butt joint face through a straight portion of a D-shaped butt joint ring 5, and an inner included angle is connected through an inner joint 4. In order to maximize the structural utilization rate of the triangular array frame plane, the butt joint area is extended to the position outside the intersection point of the three frame edges 3 so as to ensure the maximization of the available installation area of the array surface, therefore, a D-shaped butt joint ring 5 is designed at the outer side of the butt joint area along the angular bisector direction of the triangular array so as to meet the requirement of the structural dimension of the triangular array frame and simultaneously take certain bearing effect into consideration, and a strong inner joint 4 is designed at the inner side so as to bear most of the inertial load and the pneumatic load on the frame edges 3. In addition, because the planar structure utilization efficiency of frame increases, when adopting the great size antenna array face, to the transparent ripples district area requirement increase of radome 1, its transparent ripples district scope of radome 1 based on above-mentioned connected mode design is showing and is improving, can satisfy the transparent ripples requirement of antenna to the cover body.
The D-shaped butt-joint ring 5 is integrally machined from 2024-T351 materials, the main section of the D-shaped butt-joint ring is in a shape like the Chinese character 'tu', the butt-joint positions of the three combined frame rims are connected with the rims through phi 6 steel self-locking bolts, and shear flow on the rims 3 and additional bending moment caused by inflection of the rims 3 are transmitted. Meanwhile, the outer side of the earth-shaped section provides a radome 1 lapping surface for mounting the radome 1. And a sunken area with the depth of 1mm is designed in the middle section of the D-shaped butt-joint ring 5, so that process allowance is provided for the installation of the radome 1, and the installation of the radome is facilitated. The inner joint 4 at the inner side of the triangular array frame is connected with the frame edge by a phi 6 steel self-locking bolt and is used for transmitting the inertia load and the pneumatic load on the frame edge 3.
