Embodiment Construction

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

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

[0055] (1) Decompose the task to obtain the number and type of degrees of freedom of the mechanism in each working stage.

[0056] Taking the overall task of the metamorphic mechanism in a working cycle as T, the task is decomposed with the simplest function that can be realized by the conventional mechanism as the basic task unit, and n subtasks T that are completed in sequence are obtained. i , each subtask corresponds to a work stage and a mechanism configuration M i ;(i=1,2,...,n). In each cycle, the metamorphic mechanism works cyclically and performs n times of configuration transformations: configuration 1→co...

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 and relates to a method for synthesizing mechanism configurations, in particular to a method for synthesizing metamorphic mechanism configurations based on function analysis. Background technique [0002] Metamorphic mechanisms can produce continuous and orderly configuration changes according to different environments, present different topological configurations, and meet different functional requirements. How to establish the theory and method system for the configuration design of metamorphic mechanisms is the primary problem that must be faced in the design of metamorphic mechanisms, 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 configuration synthesis methods for metamorphic mechanisms. One is to start with the mathematical description of metamorphic mechanisms, and use adjacency ...
