In order to effectively suppress the transverse random vibration of a class of irregular shape and structure valve for launch vehicle in the ground test, adopting the method of combining finite element simulation and experiment, the influence of different structure tools on the transverse vibration of the valve is investigated. Moreover, the impact of arrangement position of valve and semi-circular tool assembly on transverse vibration of valve is studied. Based on the analysis of the influence of tooling of different structures on the transverse random vibration of the valve, it is proposed that semi-circular fixture can effectively reduce the transverse vibration for this kind of valve. Furthermore, when placed in the center of vibration table or near the vibration source, can decrease transverse vibration of the valve remarkably.
