Abstract: The simulation analysis of C-type accumulator no-load vibration based on modal method is presented in this paper. The simulated structural mode and natural frequency of the accumulator are in consistence with those of test results, the analysis method is verified to be effective. At the same time, an improved structural scheme is proposed regarding to the no-load vibration. A wider bracket obtained by the calculation is verified to be the optimal scheme to improve no-load vibration of C-type accumulator.
