HIGH DYNAMIC PRESSURE STANDARD USING A STEP PRESSURE GENERATOR

摘要

This paper describes how to implement a high dynamic pressure instrument using a step pressure generator and standardization based on a medium density equation. The step dynamic pressure without any big vibration due to an impulse caused by a trigger mechanism is generated upto 800 MPa. A basic design concept to eliminate the unnecessary vibration is proposed. In addition, density equations according to pressure are used to establish the high dynamic pressure standard. On the other hand, the effectiveness of conventional sebacate(di-2-ethylhexyl sebacate) oil density equations could be verified by the instrument.
