Dynamic prediction and compensation of aerocraft assembly variation based on state space model

摘要

Purpose - This paper aims to clarify the predicting and compensating method of aeroplane assembly. It proposes modeling the process of assembly. The paper aims to solve the precision assembly of aeroplane, which includes predicting the assembly variation and compensating the assembly errors. Design/methodology/approach - The paper opted for an exploratory study using the state space theory and small displacement torsor theory. The assembly variation propagation model is established. The experiment data are obtained by a real small aeroplane assembly process. Findings - The paper provides the predicting and compensating method for aeroplane assembly accuracy. Originality/value - This paper fulfils an identified need to study how the assembly variation propagates in the assembly process.
