A form-finding method for tensegrity structures based on dynamic programming

ActiveCN116502294BMeet structural requirementsAccurate form finding resultsGeometric CADNatural language data processingTheoretical computer scienceDynamic programming
The application belongs to the technical field of form-finding of tensegrity structures, and particularly relates to a form-finding method for tensegrity structures based on a dynamic programming method. For any tensegrity structure, the dynamic programming method is used to determine the connection method of all rod members in the configuration, the balance matrix theory analysis and the geometric stability determination are comprehensively used, and the configuration meeting the requirements of the tensegrity structure is obtained. The main steps are as follows: firstly, the configuration is determined, the number of nodes is determined, and the node coordinates are input; the connection method of the cable is determined; the set of optional rod members of the configuration is determined; the dynamic programming table is established, and the boundary conditions are filled; the problem is solved step by step according to the recursive formula, and whether it is a tensegrity is determined according to the constraint conditions such as the balance matrix theory analysis and the geometric stability determination; and finally, the mode of all feasible rod member combinations of the determined configuration is output.

An aircraft derivative gas turbine engine compressor inlet device

ActiveCN224621803URealize intake rectificationAvoid affecting intake efficiency
This utility model belongs to the field of gas turbine technology, and specifically relates to an air intake device for an aero-derivative gas turbine compressor. The air intake device includes an intake casing, characterized in that: a shroud is fixed inside the intake casing, an inlet rectifier cone is fixed outside the intake casing, a cleaning pipeline is installed on the inlet rectifier cone, and a hydraulic motor drive and lubrication assembly is installed in the inner ring of the intake casing. The hydraulic motor drive and lubrication assembly is enclosed within the shroud, and its pipeline is connected to the hydraulic motor drive and lubrication assembly pipeline. The beneficial effects of this utility model are: it achieves gas turbine intake rectification, avoids leakage of parts affecting intake efficiency, and reduces intake resistance. By accelerating and uniformly introducing external air into the compressor first stage through a tapered channel, it reduces airflow separation, ensures that air enters the compressor flow path smoothly along the axial direction, and avoids compressor efficiency reduction or surge due to uneven flow velocity.
