| Abstract: | For valve control cylinder system, wrong deduction of change rate of pressure with respect to time will result in mistakes of natural frequency and damping ratio of the system, which directly influences the dynamic analysis of the system. This paper presents the correct solution of natural frequency and damping ratio of valve control cylinder system. |
