In order to suppress the vibration of tubular vortex in operation, corresponding damping structure design and damping characteristics research were carried out. For the tubular vortex reducer, the design parameters of the damping structure were summarized. On this basis, the design process of the damping structure of the tubular vortex reducer was summarized. This method was used to design the damping structure and calculate the damping characteristics of an engine vortex reducer, and test verification was carried out. The results showed that the damper designed by this method has good damping effect and can reduce the stress level at key points by more than 80%. The test results and the normal pressure range to achieve the optimal damping effect were close to the calculation results, verifying the accuracy of the method in predicting the damping characteristics.
