摘  要
液压传动相比与其他传动具有体积小、可方便地实现无极调速、易实现过载保护和操作简单等优点，因此在当今工业化中应用广泛。但是由于液压系统的自身特点，其存在的液压冲击是不可避免的。与电气系统类似，液压系统中也存在着惯性元件，即液感和液容，它们和电容电感一样，有感性和容性的性质。由于其物理本质，液感和液容可以有效地抵抗液压系统中产生的液压冲击，而液感和液容又与管道的参数密切相关。基于以上理念，本文主要研究针对某一特定的液压系统，如何设置合理的管道参数才能够有效地抵抗因阀的快速启闭而引起的液压冲击。本文先采用数学计算的方法，推导出液压冲击和液容液感的数学模型以及液容液感抵抗液压冲击的数学模型，在此基础上借助AMESim进行仿真，验证数学模型的正确性，最后在Solidworks中对AMESim中仿真时用到的液压系统进行三维装配。
本文的研究成果表明，虽然管道的直径越小，产生的液压冲击越大，但是随着管道直径的变小，液压管道抵抗液压冲击的效果也随之变小。在设计液压系统的管道时，为了利用管道的感性和容性消除液压冲击，设计者应权衡利弊，设置合理的管道参数，使得管道既能有效地消除液压冲击，又不至于存在过大的液压冲击峰值。

Abstract
Hydraulic transmission compared to other small, can easily achieve stepless speed, simple operation and easy to implement overload protection, etc., it is widely used in today's industrialization. However, due to its own characteristics of the hydraulic system, hydraulic impact of its existence is inevitable. Similar to the electrical system, hydraulic system, there are also inertial element, namely a sense of liquid and liquid capacity, inductance and capacitance, as they have inductive and capacitive properties. Because of its physical nature, a sense of liquid and liquid content can effectively resist hydraulic shock generated in the hydraulic system, and a sense of liquid and liquid content is closely related to the parameters of the pipeline Based on the above ideas, this paper studies on a specific hydraulic system, how to set reasonable parameters of pipeline to be able to effectively resist hydraulic shock due to the rapid opening and closing of the valve caused. This article first method uses mathematical calculations derived hydraulic fluid capacity and fluid feeling the impact of the mathematical model and the fluid being liquid capacity to resist hydraulic shock mathematical model on the basis of the aid AMESim simulation to verify the correctness of the mathematical model, and finally Solidworks in the hydraulic system in AMESim simulation used in the three-dimensional assembly.

Results of this study show that, although the smaller the diameter of the pipe, the greater the resulting hydraulic impact, but with smaller diameter pipe, hydraulic pipe hydraulic shock resistance effect also will be smaller. In the design of the hydraulic system piping, in order to take advantage of inductive and capacitive pipeline eliminate hydraulic shock, the designer should be weighed, set reasonable parameters of the pipeline so that the pipeline can effectively eliminate hydraulic shock, but not so the existence of an excessive hydraulic peak shock.
