Method for hanging stand hanging point selection and lifting control

Abstract

The invention discloses a method for hanging stand hanging point selection and lifting control. The method is characterized by according to a finite element model of an established hanging stand, using an improved particle swarm algorithm to obtain an optimal reverse chain arrangement point; designing a theoretical lifting point and a lifting route based on finite element analysis results of an initial force and a spatial displacement of the hanging stand; acquiring an actual offset through a difference value between a theoretical space coordinate of a displacement sensor and an actual space coordinate, and then taking the actual offset as an external load and putting into the finite element model of the hanging stand; and adjusting an acting force applied to the hanging stand by a reversechain. Through establishing a multi-hanging-point system optimization model, corresponding calculation of a fitness function is performed on the optimization model, a multi-hanging-point arrangementmode is selected. For layout of the hanging point, the improved particle algorithm is used to optimize a value range and an area of the hanging point so as to reduce an arrangement number of the hanging points and save hoisting equipment.

Description

technical field [0001] The invention belongs to the construction field of hanging stands, and in particular relates to a method for selecting and lifting control points of hanging stands. Background technique [0002] Stands generally refer to the seats provided for the audience to watch large-scale collective activities such as cultural and sports, entertainment performances, etc., mainly refer to the audience seats around the performance or competition venue, such as stadium stands, concert stands, etc.; existing The large-scale stands are generally assembled from multiple stands. During the assembly process of the stands, the stands are usually hoisted by a hanging machine. When the stands reach the designated position, the stands are put down. During the lifting process of the hanging stand, it is easy to cause a certain initial geometric deviation, or the arrangement of the lifting points will lead to local stress concentration, and the local stress will cause local dam...
