本文介绍在产生液压冲击后,用联锁方程来解决液压间接冲击在特定边界条件下的非恒定流计算问题。通过建立数学模型、计算分析和实验对比,可以看出:此法在理论上严格,可以准确计算出液压间接冲击的多相压强值及其周期;还能反映出,初始压强对液压间接冲击的影响;这种计算方法能充分体现液压间接冲击内在机理及暂态过程。图8幅。
In this paper, we introduce the interlocking equation to solve the unsteady flow calculation problem of hydraulic indirect impact under certain boundary conditions after the hydraulic shock is generated. Through the establishment of mathematical model, computational analysis and experimental comparison, it can be seen that this method is theoretically rigorous and can accurately calculate the multiphase pressure value and its period of indirect impact of hydraulic pressure. It can also reflect that the initial pressure affects the hydraulic indirect impact Influence; This calculation method can fully reflect the inherent mechanism of hydraulic indirect impact and transient processes.
