Abstract: In order to solve the problems of the main equipment frame design feasible assessment of small and medium sized gas turbine test rig and the range of toughened model, the structure dynamic characteristics under load status of the main equipment frame was analyzed basing on FEM, not only for the untake/take belt box body gas turbine, but also for the dynamometer. The method of bolted surface were generalized,where the mass element method was used for solving load state, the spring element method and toughened model were used for treating bolted surface. The results indicate that as for the method of bolted surface treatment, the maximum of gas turbine base frame is 2.85%, while the minimum of the dynamometer is 19.2%. And the analysis verifies structure design to meet the requirements, and then provides the guarantee for the safe operation of the test section.
