| Abstract: | FEM analysis of a kind BRB applicable to space structures was conducted by using software ANSYS.The hysteresis curve of the BRB was obtained.By comparison with the result of experiment,the factors affecting the BRB's performance were analyzed,and the origin of the difference in the results obtained with both the FEM analysis and the experiment was also given. |
