Abstract  In order to develop a high-precision deep-sea pressure environment simulation test platform, a dual-piston high-precision water depth simulation method is proposed based on the compressibility of liquid. Firstly, the working principle of the method and the composition of the pressure simulation system are introduced; secondly, the influence of the main and auxiliary pressure systems on the measurement range and adjustment accuracy of the system is analyzed, and the physical model of the pressure system is further established and simulated. The results show that the system has good pressure following performance. Finally, a prototype experimental platform is built to carry out step-up and “diving-keeping-rising” pressure. Force experiments show that the system can achieve static accuracy of 0.02bar and dynamic accuracy of 0.1bar, which verifies the feasibility and validity of the measurement method.
