Three valve vibration modes calculated 12 volt solenoid
        The purpose of the valve vibration modes calculated to determine the use of equivalent static or dynamic analysis method for subsequent calculations to determine the first natural frequency is greater than or less than 33Hz.
        Fixed constraints on the end face of the valve inlet and outlet flanges, modal calculation, extract the natural frequency of the third order, the calculation results are shown in Table 1, the first to the third order mode shapes shown in Figure 2.high pressure hydraulic fittings
