Abstract: According to the dynamic characteristics of a new capacitive high bore pressure tester,which is decided by the vibration characteristics of the pressure tester shell subjected to pressure,the dynamic model of the tester shell under external pressure was established,and the dynamic properties of the tester shell were studied.The calculation results show that the first vibration frequency of shell radial vibration is above 75kHz,and the frequency spectrum of the bore pressure is below 5kHz.Consequently,the influence of shell vibration on the test precision of bore pressure can be ignored.
