【正文】 摘要 隨著科學(xué)技術(shù)的不斷發(fā)展，對機械產(chǎn)品的要求也越來越高。機械產(chǎn)品需要滿足社會的需要，就應(yīng)該具有高精度、高效率、通用性和靈活性等性能，加上機械產(chǎn)品不斷加快的更新?lián)Q代速度，因此對檢驗設(shè)備也相應(yīng)地提出了精度高、效率高、通用性好和靈活性強的要求。電子萬能試驗機作為試驗機床家族中的高端產(chǎn)品，在現(xiàn)代機械行業(yè)領(lǐng)域內(nèi)被越來越多的采用，具有機型美觀，操作簡單，系統(tǒng)工作可靠，測量精度高等特點。 本設(shè)計為 1KN 拉壓萬能試驗機的結(jié)構(gòu)設(shè)計，試驗機本體仿照WDW100C1000C 進行設(shè)計，結(jié)構(gòu)上可滿足相應(yīng)的參數(shù)要求，試驗機重要部分的強度和剛度經(jīng)過軟件的模擬分析，滿足可靠性試驗臺的試驗要求。 關(guān)鍵詞： 加工中心； 試驗機；可靠性；拉壓力；結(jié)構(gòu)設(shè)計 Abstract With the continuous development of science and technology, the requirements of mechanical products have bee more products need to meet the needs of society, they should have high accuracy, high efficiency, versatility and flexibility performance． Coupled with the condition that upgrading speed of mechanical products is accelerating,so the machine equipment is raised correspondingly high precision, high efficiency, good versatility and flexibility requirements. Electronic universal testing machine， as a highend product of the CNC machine tool family ， is being more and more used in the field of modern machinery industry ,its capacity with Beautiful models, Simple Operation , high precision, High efficiency, high versatility features. Testing machine plays an important role on today39。s Machining Center, whose reliability has a huge effect on machine reliability. In order to improve the MTBF level of Machining Center, it is significant to invent a testing bed to test the reliability of Various materials. The article is the strutural design of the 1KN tension and pression testing test rig design ontologies modeled on the WDW100C1000C, the structure can meet the requirement of the Requirements of the corresponding strength and stiffness of important part of test bench is simulated by analysis software to meet the reliability test requirements.
