摘　　要：三组元水下热动力系统是近期最热门的研究课题之一。本文提出了一种端面间隙控制方法,通过分析影响容积式比例控制器工作压差和泄漏量的各种因素,给出了比例控制器的精度分析方法。分析可知:比例控制器的比例精度主要由各路的泄漏量决定,而泄漏量由间隙和工作压差决定;提出的端面间隙控制方法,可有效地控制内泄漏,提高比例精度。该精度分析方法及其间隙控制方案对各种液压马达的设计具有参考价值。Tri-propellant thermal propulsion system is one of the hotspot subjects in the research field of underwater vehicles recently. To improve efficiency of underwater vehicles, a method of radial clearance control of the tri-proportion has been proposed in the paper. Based on analyzing the factors which influence the pressure difference and leakage oftri-ptoportion controller, a way which is used for precision analysis and proportion adjustment has been given by the medianoptimizing theory. The results show that accuracy of the proportion controller is depended on all the leakage, while the leakage is decided by radial clearance and pressure difference; the leakage can be controlled effectively and the accuracy of the proportion can be improved obviously with the radial clearance control method. The method of accuracy analysis and clearance control has reference value on design various hydraulic motors
