摘要
在我国大发展、快发展的大背景下,我们的国民经济也处于不断上升的过程中,工业的发展成为带动经济发展的重要力量。在这过程中,液压技术也得到了较大的发展空间,液压技术渗透在我国工业的各项领域中,其中,液压传动是一门较新的技术,虽然仅短短几十年的发展历程,可是如今却被大规模地应用在矿山、冶金机械、工程机械、机床等多种机械以及相关的武器装备里。
抗冲击性能作为产品可靠性的重要组成部分,现在已备受产品生产者和使用者的关注。冲击试验则是测试产品抗冲击性能约一个重要手段。为了提高检测产品的抗冲击性能的试验水平,改进和完善冲击试验机性能则是一个重要的研究方向。本论文主要设计了一种对被试件进行冲击性能试验的试验台。介绍了该试验台液压系统和测控系统的设计及工作原理,确定了元件的主要参数。验算液压系统的性能,以及液压控制系统的设计步骤,以及设计液压系统时应注意的问题。在综合国内外文献的基础上介绍了液压冲击试验机的发展历史,研究与应用现状,并介绍了液压冲击试验与冲击波形的运用状况。

Abstract
In our country under the background of great development, fast development, our national economy is rising in the process, the development of industry e the important force in driving the development of economy. Hydraulic technology in the process, also get the larger development space, hydraulic technology in the domain of industry in China, among them, the hydraulic transmission is a relatively new technology, although only a short span of decades of development, but now has been largely used in mining, metallurgical machinery, engineering machinery, machine tools and various machinery and related equipment.
Shock resistance as an important part of product reliability, product producers and users of the watches now. Impact test is a test product shock resistance about an important means. In order to improve the level of detection products shock resistance of the test, to improve and perfect the impact testing machine performance is an important research direction. This paper mainly designs a shock performance testing of the specimens test rig. The test rig of hydraulic system are introduced and the design and working principle of measurement and control system, determine the main parameters of the element. Checking the performance of hydraulic system and hydraulic control system design steps, and the problems should be paid attention to when design the hydraulic system. On the
