【摘要】：使用液压驱动的深海载人潜水器,压力补偿器可消除海水压力对液压系统影响,补偿器内径作为其关键结构参数,其设计长期以来一直依靠经验,为解决此问题,通过数学建模,得到补偿压力波动峰值和补偿膜片内外压差峰值,得出补偿器内径是影响这两者的主要结构参数,其值越大,膜片内外压差峰值越小;结合滚动膜片强度理论,依据滚动膜片内外压差峰值须小于滚动膜片安全工作压力这一准则,得到补偿器内径的边界约束和取值方法,基于补偿器内径这一关键参数,压力补偿器可以实现精确以及可靠性设计,此设计方法在一些深海设备上获得应用,实际应用证明了该方法的可行性和有效性。
[Abstract]:Using hydraulic driven deep-sea manned submersible, the pressure compensator can eliminate the influence of seawater pressure on hydraulic system, and the inner diameter of compensator is the key structural parameter. Its design has been relying on experience for a long time, in order to solve this problem. Through mathematical modeling, the peak value of compensation pressure fluctuation and the peak value of compensation pressure difference inside and outside of diaphragm are obtained, and the main structural parameters affecting them are the inner diameter of compensator, the larger the value, the smaller the peak value of pressure difference inside and outside of diaphragm. According to the criterion that the peak value of pressure difference inside and outside the rolling diaphragm must be smaller than the safe working pressure of the rolling diaphragm, the boundary constraint and the method of selecting the inner diameter of the compensator are obtained, based on the key parameter of the inner diameter of the compensator. The pressure compensator can be designed accurately and reliably. This design method has been applied to some deep-sea equipments. The practical application has proved the feasibility and effectiveness of the method.
