[2]疲勞試驗機分類編輯疲勞試驗機根據(jù)試驗頻率可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。頻率低于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的成為高頻疲勞試驗機，300Hz以上的成為超高頻疲勞試驗機。機械與液壓式一般為低頻，電機驅(qū)動一般為中頻和低頻，電磁諧振式為高頻，氣動式和聲學(xué)式為超高頻。復(fù)合材料不可以用電磁式高頻疲勞試驗機進行疲勞試驗，因為電磁式是采用電磁諧振原理驅(qū)動的，與試樣的剛性有關(guān)，所以復(fù)合材料只能用電機驅(qū)動疲勞試驗。[3]疲勞試驗機工作原理編輯高頻疲勞試驗機根據(jù)電磁諧振的原理工作，依靠電磁鐵的震蕩施加載荷，是載荷比較大20KN-300KN，頻率80-250Hz測試時間短的優(yōu)先。需要調(diào)頻率，頻率時固定幾個檔，根據(jù)使用客戶的反饋，調(diào)頻操作比較麻煩。低頻疲勞試驗機根據(jù)電液伺服的原理工作，依靠液壓作動缸的往復(fù)運動施加載荷，大載荷5KN-1000KN低頻率0-10Hz的優(yōu)先，一般建議在10Hz左右使用，更高的頻率對于液壓伺服閥、密封圈等等部件的摩擦損傷太大，后面的維護成本太高，不建議使用更高頻率。如果不考慮維護成本，使用20Hz，30Hz也是可以的。上海構(gòu)件彎曲疲勞試驗機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3。</p><div

突然斷裂。疲勞斷口明顯地分為兩個區(qū)域：較為光滑的裂紋擴展區(qū)和較為粗糙的斷裂區(qū)。裂紋形成后，交變應(yīng)力使裂紋的兩側(cè)時而張開時而閉合，相互擠壓反復(fù)研磨，光滑區(qū)就是這樣形成的。載荷的間斷和大小的變化，在光滑區(qū)留下多條裂紋前沿線。至于粗糙的斷裂區(qū)，則是***突然斷裂形成的。統(tǒng)計數(shù)據(jù)表明，機械零件的失效，約有70%左右是疲勞引起的，而且造成的事故大多數(shù)是災(zāi)難性的。因此，通過實驗研究金屬材料抗疲勞的性能是有實際意義的動態(tài)疲勞試驗機優(yōu)點編輯目前市場上有電液伺服的和非液壓油源驅(qū)動的，目前市場上大部分用的是液壓驅(qū)動的高載荷的動態(tài)疲勞試驗機，用于大的零部件或建筑工程等方面的測試，非液壓油源疲勞試驗機一般用于載荷要求較小或位移較小，高精度的測試，非液壓油源動態(tài)疲勞試驗機的優(yōu)點如下：1、干凈；2、穩(wěn)定；3、噪音低；4、安裝維護簡單方便；5、省電省水；6、安全；7、使用壽命長等。</p>主機采用雙立柱單空間結(jié)構(gòu)，由機座、作動器、立柱、可保證拉伸、壓縮疲勞試驗的特殊液壓夾頭，高精度負荷傳感器和帶液壓鎖緊裝置的無間隙可移動橫梁等組成。橫梁全程液壓提升、下降，具有液壓鎖緊功能，易于定位，鎖緊可靠，操作方便。橫梁位置在50～600mm范圍內(nèi)任意調(diào)整。作動器采用試臺、油缸一體化設(shè)計，高剛性，比較傳統(tǒng)的組合式油缸，泄漏環(huán)節(jié)少，更耐磨，剛度更高。 <p> 液壓源由油箱，與伺服電機一體的進口內(nèi)嚙合齒輪泵，電磁閥及閥塊，冷卻器，溢流閥，壓力表等組成。液壓源采用無泄漏技術(shù)，在任何工作環(huán)境和工作狀態(tài)下，油液無外泄及滴漏；液壓源采用降噪音技術(shù)，減少了運行噪音； </p> <p> 液壓源動力采用自適應(yīng)型的伺服泵技術(shù)，即根據(jù)試驗需求，設(shè)定頻率和振幅，當(dāng)這兩個參數(shù)給定的時候，控制系統(tǒng)將根據(jù)兩個參數(shù)自動調(diào)整油泵的流量，從而將系統(tǒng)的發(fā)熱量降到比較低，同時，系統(tǒng)的噪音也降到比較低，系統(tǒng)所消耗的電力、水能源都將降到比較低。該技術(shù)已在我公司大流量的疲勞試驗機上應(yīng)用，其效果十分明顯。是一種主要用于測定金屬及其合金材料在室溫狀態(tài)下的拉伸、壓縮或拉、壓交變負荷的疲勞性能試驗的機器4。</p><div
