摘要	Large rigid-body displacement parameters within finite element analysis results are hard to be extracted. We propose an algorithm to solve this problem. Firstly, the constraint equations are established. The linear coordinate equations and objective function are then constructed. By using Lagrange multiplier method and Taylor series expansion, the solution algorithm is derived. Numerical simulation results reveal that the algorithm can separate ultra-large rigid-body rotation within the range of +/- 180 degrees with the accuracy of less than 1 parts per thousand and the solving efficiency is more than twice that of the trigonometric function method. The application experiments show that the algorithm can meet the actual engineering requirements.
