The method of optimal design for parts of hoop detachable connections
The article considers the main provisions of method developed in JSC "IrkutskNIIhimmash" and applied to optimal design of hoop detachable connections with high pressure. The method is based on the finite element method combined with applied methods of multivariate optimization. The proposed method allows designing a hoop detachable connection of the minimum weight, which satisfies restrictions on strength and tightness. Following the method, the author software has been developed. Being the part of the software system COMPASS, the author software is to design engineering equipment. The proposed method and software program enabled to introduce a number of typical-sized hoop detachable connections at a chemical plant JSC "Angarsk Petrochemical Company" of petroleum company "Rosneft". Thus, this method and the software program have allowed optimizing maintenance and repairing costs for high-pressure equipment, and decreasing occurrence rate of industrial injuries during repairing operations.
