Embodiment Construction

[0053] The invention is described in further detail below in conjunction with the accompanying drawings and embodiments, but is not used as a basis for any limitation of the invention.

[0054] like figure 1 As shown, a kind of metamorphic mechanism configuration synthesis method based on functional analysis of the present invention, comprises the steps:

[0055] (1) The task is decomposed, and the number and type of degrees of freedom of the mechanism in each work stage are obtained.

[0056] Take the overall task of the metamorphic mechanism in a working cycle as T, and take the simplest function that can be realized by the conventional mechanism as the basic task unit to decompose the task, and obtain n subtasks T to be completed in sequence i , each subtask corresponds to a work phase and an institutional configuration M i ; (i=1,2,...,n). In each cycle, the metamorphic mechanism works cyclically and performs n times of configuration transformation: configuration 1→conf...

Abstract

The invention relates to a metamorphic mechanism configuration synthesis method based on functional analysis. The method includes: decomposing a work task of a mechanism to acquire degree of freedom that the mechanism needs to have at each stage; performing aggregation operation to acquire number and type of degree of freedom of a metamorphic source mechanism; synthesizing according to a conventional mechanism synthesis method to acquire various possible configurations of the metamorphic source mechanism; screening according to configuration transformation requirements of the metamorphic process to acquire a good metamorphic source mechanism original configuration; integrating kinematic pairs in the original configuration to acquire a metamorphic kinematic pair and the metamorphic source mechanism; combining the metamorphic source mechanism with each working stage to acquire each configuration of the metamorphic mechanism, and using a metamorphic equation to describe the metamorphic process between the metamorphic source mechanism and each working stage mechanism as well as between each two adjacent working stage mechanisms.

Description

technical field [0001] The invention belongs to the field of mechanical mechanism theory, relates to a method for mechanism configuration synthesis, in particular to a metamorphic mechanism configuration synthesis method based on function analysis. Background technique [0002] The metamorphic mechanism can produce continuous and ordered configuration changes according to different environments, present different topological configuration states, and meet different functional requirements. How to establish the theory and method system of metamorphic mechanism configuration design is the primary problem that must be faced when designing metamorphic mechanism, and it is also one of the key problems in the development and application of metamorphic mechanism theory. At present, there are three main types of metamorphic mechanism configuration synthesis methods. One is to start from the mathematical description of metamorphic mechanism, and use adjacency matrix, map, etc. to des...
