深海超高压环境模拟试验装置是深海关键技术与装备研究中必不可少的测试装置。采用传统的一体式压力筒研制大直径、超高压试验装置时难以克服应力集中的问题,安全性较低且造价昂贵。采用预应力钢丝缠绕技术研制的深海超高压环境模拟试验装置克服了其局限性,该装置是目前国内工作压力最高、可实现筒内环境数据监测且升降压自动控制的压力试验装置。文中简要介绍了该装置的系统组成及研制过程中主要关键技术问题及解决方法,最后介绍了典型实验应用,为深海超高压环境模拟试验装置的研制与应用提供参考。

The ultrahigh pressure testing equipment for the environment simulation of deep-sea is an essential testing device in the research of key technologies and equipment in the deep sea. It is difficult to overcome the problems of stress concentration by using a conventional integrated pressure cylinder. The method to develop a large diameter and ultrahigh pressure testing equipment is accompanied by low safety and high costs. In this paper, the ultrahigh pressure testing equipment for the environment simulation of deep-sea developed by pre- stressed steel wire-winding technology has been developed to overcome its limitations, and the device is currently under the highest working pressure in China. Meanwhile, it can monitor the environmental data in the cylinder and can achieve automatic control of lifting pressure. This paper briefly introduces the system components, the key technical problems and solutions in the development process. Finally, the typical experiment application of the equipment is introduced, which will provide beneficial reference for the development and application of experimental devices used to simulate ultrahigh pressure environment testing in the deep sea.
