Problems solved by technology
In engineering practice, after the stress concentration and stiffness weakening caused by the special-shaped large opening of the cylinder exceeds a certain level, the installation error of the optical off-axis angle α will exceed the standard, and the supporting precision optical equipment cannot work normally. In extreme cases It may even cause the overall collapse of the horizontal vacuum vessel and cause major safety accidents

The invention discloses a horizontal type vacuum container tank having an inclined tapered connection pipe. An optical inclined tapered cylinder is arranged on a side of the tank in a tilt manner. Thecone angle of the optical inclined tapered cylinder is Beta in a range from 0 DEG to 45 DEG. The small end diameter is 420mm. An included angle between central axis of the optical inclined tapered cylinder and the central axis of the main tank is an off-axis angle Alpha in a range from 30 DEG to 90 DEG, and the central axis of the optical inclined tapered cylinder and the central axis of the maintank are co-planar and cross each other. An intersecting line of an intersection hole of the inclined tapered connection pipe and the tank is a three-dimensional spatial curve forming an oval planarcurve in vertical face rectangular projection. The intersecting line of the hole is a continuous smooth curve composed of obtuse angle curves and acute angle curves in geometry. The oval curve has four characteristic points which are Theta 1, Theta 2, Theta 3 and Theta 4. Compared with the prior art, the horizontal type vacuum container tank having the inclined tapered connection pipe provided bythe invention is distinctive in effect when being applied to engineering practice.
Description
technical field [0001] The invention belongs to the technical field of vacuum vessels for spacecraft heat tests. Specifically, the invention relates to a horizontal vacuum vessel cylinder with an oblique conical nozzle structure, which is used to guide related openings and reinforcement structures. Background technique [0002] In the development of space environment simulation equipment, due to the functional requirements of the system, it is necessary to protrude various connecting structures from the vacuum vessel cylinder. According to the geometric position of the connecting pipe relative to the cylinder, it can be divided into orthogonal connecting pipes, circumferential mitered pipes and axial mitered pipes. Due to the asymmetric characteristics of the axially mitered pipe structure in the transverse direction of the container cylinder, the stress concentration in the area where the pipe intersects with the cylinder is significantly greater than that of the orthogonal...
