Planning system and method for shield body assembly sequence of shield machine

Abstract

The invention provides a planning system and method for a shield body assembly sequence of a shield machine, and aims to lower the complexity of planning the shield body assembly sequence of the shield machine and obtain the assembly sequence meeting user demands to the maximum extent. The system comprises an assembly resource management module connected with a database, an assembly sequence planning module and a virtual assembly simulation module, wherein the assembly resource management module stores resources required for planning the shield body assembly sequence of the shield machine; the assembly sequence planning module stores various information required for planning a to-be-assembled shield body assembly sequence of the shield machine, and calculates and selects a pre-planning result of a shield body part assembly sequence of the shield machine by utilizing a discrete particle swarm universal gravitation search algorithm; and the virtual assembly simulation module performs verification on the feasibility of the pre-planning result, and determines and outputs a plan of the to-be-assembled shield body part assembly sequence of the shield machine. The planning system is flexible and low in assembly sequence planning complexity.

Description

technical field [0001] The invention belongs to the technical field of computer-aided process design, and in particular relates to a planning system and method for shield body assembly sequence of a shield machine, which can be used to improve assembly efficiency in production, and can assist and guide operators. Background technique [0002] Assembly sequence planning is to plan and select the assembly sequence of parts according to certain requirements on the basis of assembly information model, which is the most important issue in industrial manufacturing process. Optimizing the assembly sequence can greatly reduce the cost and time of industrial products. In the process of assembly sequence planning, considering the relevant physical constraints and geometric constraints in the assembly program, how to choose an optimal assembly sequence planning from many geometrically feasible assembly sequence planning becomes a key point. sexual issues. The evaluation criteria of t...

Problems solved by technology

However, the disadvantages of this system are: the system’s planning of the parts assembly sequence in the virtual assembly process of the shield machine is somewhat divorced from the actual production. The disassembly method can only be used to plan the assembly sequence of the same product, and it cannot be assembled flexibly. At the same time, the system fails to connect with the database, that is to say, the parts added in the database cannot be updated to the assembly process module in time, which is not convenient for subsequent staff to combine the assembly process module with the design and development shield machine-associated
