VIBRATION RESISTANCE OF THE AUTOMATIC DEVICE OF AXIAL UNLOADING OF THE TPU
The results of vibration resistance research of automatic device axial unloading of turbopump unit (TPU) are reviewed. The mathematical model of the device of this type is developed. She allows to define at a design stage influence on vibration resistance system key parameters -a range of regulation of axial force, volume of the unloading chamber and compressibility of a working liquid. Frequency characteristics vibration activity and transients on axial moving of a rotor influences in the form of jump and blow are resulted.
