由于研制的充液拉深装备具有超高压特点，为适应计算机过程控制的需要，超高压压力控制系统中采用了减压装置，文中对减压装置的动态特性、缸体的强度、以及密封结构等问题进行了分析研究。并对超高压压力控制系统的动态响应性能进行了分析，为压力控制系统方案的确定提供了一定的理论依据，并根据实际情况选择了合适的超高压压力控制系统形式。
In order to meet the need of computer process control, the decompression device is adopted in the superhigh pressure control system. The dynamic characteristics of the decompression device, the strength of the cylinder body and the structure of the sealing structure And other issues were analyzed. The dynamic response performance of the EHV pressure control system is analyzed, which provides a theoretical basis for the determination of the pressure control system plan. According to the actual situation, the suitable EHV pressure control system is selected.
