摘要
在我國大發(fā)展、快發(fā)展的大背景下,我們的國民經(jīng)濟也處于不斷上升的過程中,工業(yè)的發(fā)展成為帶動經(jīng)濟發(fā)展的重要力量。在這過程中,液壓技術也得到了較大的發(fā)展空間,液壓技術滲透在我國工業(yè)的各項領域中,其中,液壓傳動是一門較新的技術,雖然僅短短幾十年的發(fā)展歷程,可是如今卻被大規(guī)模地應用在礦山、冶金機械、工程機械、機床等多種機械以及相關的武器裝備里。
抗沖擊性能作為產品可靠性的重要組成部分,現(xiàn)在已備受產品生產者和使用者的關注。沖擊試驗則是測試產品抗沖擊性能約一個重要手段。為了提高檢測產品的抗沖擊性能的試驗水平,改進和完善沖擊試驗機性能則是一個重要的研究方向。本論文主要設計了一種對被試件進行沖擊性能試驗的試驗臺。介紹了該試驗臺液壓系統(tǒng)和測控系統(tǒng)的設計及工作原理，確定了元件的主要參數(shù)。驗算液壓系統(tǒng)的性能，以及液壓控制系統(tǒng)的設計步驟，以及設計液壓系統(tǒng)時應注意的問題。在綜合國內外文獻的基礎上介紹了液壓沖擊試驗機的發(fā)展歷史,研究與應用現(xiàn)狀,并介紹了液壓沖擊試驗與沖擊波形的運用狀況。
關鍵詞：液壓系統(tǒng)；測試；性能
Abstract
In our country under the background of great development, fast development, our national economy is rising in the process, the development of industry become 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 basis of comprehensive literature at home and abroad to introduce the development history of hydraulic impact testing machine, research and application status quo, and introduces the hydraulic impact test and the application of shock wave.
Key words: hydraulic system; test ;performance
