平板压力阀减速顶是一种新型减速顶,它结构简单、制动功较高。由于采用了平板压力阀,故消除了液动力的影响,使这种减速顶压力变化平稳。为了从理论上对这种平板压力阀工作特性进行探讨,作者用流体力学和液压流体力学的基本理论,推导了平板压力阀压力分布及轴向力变化规律,同时分析了影响压力阀超调特性的诸因素,为新型减速顶的结构设计和试验方案提供依据。
Flat pressure valve deceleration top is a new type of deceleration top, which has a simple structure, high braking power. As a result of the flat-plate pressure valve, it eliminates the impact of hydrodynamic, so that slow down top pressure changes smoothly. In order to theoretically study the working characteristics of this type of plate pressure valve, the author derives the pressure distribution and axial force variation of the plate pressure valve by using the basic theory of fluid mechanics and hydraulic fluid mechanics, Of the factors that provide the basis for the structural design and test program of the new decelerator.
