• Assembly variation analysis
• Method of power balance
• Sheet metal parts

Purpose - The purpose of this paper is to propose a new assembly variation analysis model to analyze assembly variation for sheet metal parts. The main focus is to analyze assembly processes based on the method of power balance.
Design/methodology/approach - Starting with issues in assembly variation analysis, the review shows the critical aspects of tolerance analysis. The method of influence coefficient (MIC) cannot accurately analyze the relationship between part variations and assembly variations, as the welding point is not a point but a small area. Therefore, new sensitivity matrices are generated based on the method of power balance.
Findings - Here two cases illustrate the processes of assembly variation analysis, and the results indicate that new method has higher accuracy than the MIC.
Research limitations/implications - This study is limited to assembly variation analysis for sheet metal parts, which can be used in auto-body and airplane body.
Originality/value - This paper provides a new assembly variation analysis based on the method of power balance.
