          單環(huán)鏈循環(huán)載荷疲勞試驗(yàn)機(jī)測(cè)試方法

          來(lái)源:濟(jì)南中創(chuàng)工業(yè)測(cè)試系統(tǒng)有限公司   2022年10月08日 10:56  

          單環(huán)鏈循環(huán)載荷疲勞試驗(yàn)機(jī)主要適用于窄軌車(chē)輛單環(huán)鏈的循環(huán)疲勞、循環(huán)次數(shù)、載荷疲勞、往復(fù)疲勞、壽命、耐久疲勞、脈動(dòng)循環(huán)疲勞等性能測(cè)試。

          1、單環(huán)鏈疲勞試驗(yàn)時(shí)的上限應(yīng)力和下限應(yīng)力應(yīng)滿(mǎn)足表1規(guī)定的。

          單環(huán)鏈上下限應(yīng)力表1&nbsp;

          2、單環(huán)鏈循環(huán)疲勞測(cè)試時(shí),上限負(fù)荷和下限負(fù)荷應(yīng)復(fù)合表2規(guī)定的。

          單環(huán)鏈上下限負(fù)荷表2&nbsp;

          3、被試樣在表2所列的上限、下限脈動(dòng)作用下,其脈動(dòng)循環(huán)次數(shù)應(yīng)不低于30000次。

          &nbsp; &nbsp;&nbsp;單環(huán)鏈循環(huán)疲勞試驗(yàn)機(jī)試樣夾持

          窄軌車(chē)輛單環(huán)鏈依據(jù)MT 244.1-2005 煤礦窄軌車(chē)輛連接件 連接鏈 標(biāo)準(zhǔn)而生產(chǎn)驗(yàn)收的。

          單環(huán)鏈的疲勞試驗(yàn)應(yīng)符合下表的規(guī)定,試驗(yàn)中不允許出現(xiàn)明顯裂紋。當(dāng)疲勞試驗(yàn)達(dá)到規(guī)定次數(shù)時(shí),單環(huán)鏈如果出現(xiàn)裂紋,則應(yīng)對(duì)該試樣進(jìn)行破斷拉力試驗(yàn),其破斷負(fù)荷應(yīng)不低于360kN。
