高頻疲勞試驗機特別是電機式高頻疲勞試驗機還在零部件疲勞試驗領(lǐng)域有較廣的應(yīng)用。[1]高頻疲勞試驗機國內(nèi)外現(xiàn)狀編輯疲勞試驗機按頻率分為低頻疲勞試驗機、中頻疲勞試驗機、高頻疲勞試驗機、超高頻疲勞試驗機。低頻低于30Hz的稱為低頻疲勞試驗機，30-100Hz的稱為中頻疲勞試驗機，100-300Hz的稱為高頻疲勞試驗機。300Hz以上的稱為超高頻疲勞試驗機。機械與液壓式一般為低頻，機電驅(qū)動為中頻和低頻，電磁諧振式為高頻，氣動式和聲學式為超高頻。國外對高頻疲勞試驗機的研究開發(fā)相比國內(nèi)早很多，瑞士Amsler和英國Instron公司對高頻疲勞試驗機的研發(fā)比中國相對較早。而中國國內(nèi)對于高頻疲勞試驗機的研究相對滯后，主要的研究廠家為長春試驗機研究所和紅山試驗機廠兩家。在上世紀50年代末期，參考瑞士Amsler公司的10HFP422為主要的研究對象，對其進行學習、分析、研究，1968年末國內(nèi)參照英國Instron公司的許多產(chǎn)品，特別是英國公司的1603型機器，這種機型的技術(shù)對國內(nèi)的高頻試驗機的制造有著重大的影響，該機型主機結(jié)構(gòu)方面和電控單元在70年代時影響高頻疲勞試驗機的發(fā)展，所以國內(nèi)高頻疲勞試驗機在發(fā)展過程中又借鑒了許多Instron的新技術(shù)和Amslerd的機械單元和電控單元產(chǎn)品。浙江拉伸疲勞試驗機疲勞試驗機也將更加的人性化、智能化和功能化8。</p><div

動力單元中有由電磁振動器提供振動動力源來提供激勵，形成振動源。若電磁振動器輸出的激振力的頻率相位值與整機系統(tǒng)的固有頻率相同，則整個振動系統(tǒng)產(chǎn)生共振，則配重質(zhì)量物體在整機上產(chǎn)生共振現(xiàn)象，輸出的慣性力往復作用于被測試試件上，以此完成疲勞測試。電液伺服型疲勞試驗機是以恒壓伺服液壓泵站作為動力源來對試件進行加載。氣壓驅(qū)動型疲勞試驗機是以恒壓伺服氣壓泵站作為動力源來對試件進行加載。杠桿、離心機構(gòu)驅(qū)動型和曲柄機構(gòu)驅(qū)動型疲勞試驗機依靠機械結(jié)構(gòu)的直線行程來構(gòu)成機器的動力源。[1]高頻疲勞試驗機電液高頻編輯疲勞試驗機是一種主要用于在室溫狀態(tài)下，測定金屬及其構(gòu)件的疲勞性能、疲勞壽命，完成預制裂紋及裂紋擴展等疲勞試驗的機器。試件在激振器產(chǎn)生的交變載荷作用下進行斷裂韌性試驗，測試金屬材料裂紋擴展速率及材料的門坎值。當激振系統(tǒng)的振動頻率等于系統(tǒng)自身的固有頻率時，即系統(tǒng)發(fā)生共振，所產(chǎn)生的微小激振力經(jīng)過放大后作用在試件上可進行材料疲勞試驗。電液高頻疲勞試驗機由于其動態(tài)響應(yīng)快、輸出功率大等優(yōu)點，因而在疲勞試驗機領(lǐng)域得到較廣應(yīng)用。[2]結(jié)構(gòu)電液高頻疲勞試驗機的實物圖電液高頻疲勞試驗機的激振器被安裝在試驗機的底座內(nèi)。</p><p>

7.試樣斷裂時的伸長率（扯斷伸長率）。二、根據(jù)以上所測參數(shù)的要求。橡膠拉伸試驗過程中需要**的數(shù)據(jù)有兩項：拉力力值和標距變化量。所以用于測試橡膠拉伸性能的橡膠拉力試驗機必須滿足以下四個要求：1.大行程。由于橡膠在拉伸時變形量很大，尤其是乳膠制品，伸長率有可能高達1000%以上。所以在橡膠試樣斷裂之前，必須保證夾持器有足夠的行程。2.高精度及高頻率的數(shù)據(jù)采集。拉伸橡膠不需要很大的力，拉力測量范圍不需要很大，所以需要力值的精度較高。一般要求測力儀，拉力機，硫化儀能夠求取小數(shù)點后兩位以上精度的力值。此外由于檢測橡膠拉伸性能需要拉伸過程中的數(shù)個拉力值，而拉伸試驗又不可重復，所以即時準確記錄每個試驗段的拉力力值對于試驗成敗起著非常重要的作用。3.準確的標距測量和記錄裝置（如圖）。試樣標距的測量是計算橡膠伸長率的重要數(shù)據(jù)，所以橡膠拉伸試驗中拉力試驗機必須準確地測量試樣的應(yīng)變量，并即時地記錄下來。4.可以準確描述應(yīng)力－應(yīng)變曲線的裝置。拉伸試樣中的拉力值和標距之間有著密切的聯(lián)系，例如：試樣的定伸應(yīng)力需要測量試樣拉伸到給定伸長率的力值，而定應(yīng)力則需要測量試樣拉伸到給定應(yīng)力的標距。試驗完成后。疲勞試驗機特點是可以實現(xiàn)高負荷、高頻率、低消耗，從而縮短試驗時間，降低試驗費用8。浙江拉伸疲勞試驗機</p><p
