拉力試驗(yàn)機(jī)由于其應(yīng)用范圍***而被廣大客戶所使用，但是，針對(duì)不同的材料，不同的檢測(cè)項(xiàng)目，所需要的拉力試驗(yàn)機(jī)的主要功能自然不盡相同，如何挑選一臺(tái)既稱心如意，又能滿足自己要求的試驗(yàn)機(jī)，需要投入一定的精力來考慮。不同的材料選用不同的拉力試驗(yàn)機(jī)。1.薄膜材料，主要檢測(cè)材料的拉力和伸長(zhǎng)率，由于薄膜材料大多伸長(zhǎng)率較高，因此，需要大行程的試驗(yàn)機(jī)。比如行程在1米的拉力試驗(yàn)機(jī);2.橡膠材料,主要檢測(cè)材料的抗拉強(qiáng)度和伸長(zhǎng)率，該材料有較高的伸長(zhǎng)率，有時(shí)可達(dá)到1000%以上，必須使用大行程拉力試驗(yàn)機(jī)，通常試驗(yàn)空間不會(huì)低于900mm，甚至更大。該材料對(duì)伸長(zhǎng)率的檢測(cè)要求較高，以位移來代替變形已經(jīng)不能滿足試驗(yàn)要求，因此，大變形測(cè)量系統(tǒng)是比不缺少的。江西標(biāo)準(zhǔn)型號(hào)拉力試驗(yàn)機(jī)拉力試驗(yàn)機(jī)如何測(cè)試物體的屈服強(qiáng)度。</p><div

拉力機(jī)傳感器力量值跳動(dòng)比較大，是什么問題呢？答：力量跳動(dòng)大，首先要到校準(zhǔn)中，確認(rèn)下力量AD值***有幾位跳動(dòng)，如果是***3-4位跳動(dòng)，則表明AD采樣是正常的，跳動(dòng)大，可能是沒有校準(zhǔn)引起的，請(qǐng)重新校準(zhǔn)一下。另外，如果在校準(zhǔn)時(shí)，發(fā)現(xiàn)掛砝碼和不掛砝碼AD值差別不大，則需要檢查傳感器接線是否正確，或者傳感器有沒有損壞。如果AD值跳動(dòng)很大，***4-5位甚至更多為在跳動(dòng)，則表明輸入AD信號(hào)就不正常。則要從兩方面分析,AD不正常是干擾引起，還是板子本身AD模塊不正常。因此首先要排除干擾影響，將主板從機(jī)器中取出，板子只接電源，串口，力傳感器，確認(rèn)下AD跳動(dòng)有幾位，如果還是跳動(dòng)很大，則應(yīng)該是板子本身問題，需要返給我們維修。如果這樣跳動(dòng)不大，則表明是干擾導(dǎo)致AD跳動(dòng)，則需要檢查地線是佛接好，傳感器屏蔽線是否有接。

拉伸速度試驗(yàn)機(jī)的影響隨材料的不同而有所差異，因此做拉伸試驗(yàn)時(shí)必須嚴(yán)格按照標(biāo)準(zhǔn)試驗(yàn)方法規(guī)定的速率進(jìn)行試驗(yàn)，否則會(huì)對(duì)試驗(yàn)結(jié)果的準(zhǔn)確性造成影響。 </p> <p> <p> 1.抗拉強(qiáng)度：抗拉強(qiáng)度隨著試驗(yàn)速度的上升，抗拉強(qiáng)度增大，但到達(dá)一定階段后趨于穩(wěn)定電子萬能試驗(yàn)機(jī)橡膠拉力試驗(yàn)機(jī) </p> <p> 2.屈服強(qiáng)度：試驗(yàn)速度較慢時(shí)，屈服強(qiáng)度與抗拉強(qiáng)度相差比較大；試驗(yàn)速度愈快，屈服強(qiáng)度與抗拉強(qiáng)度的差值逐漸減少。 </p> <p> 3.斷后延伸率：拉伸速度的提高使斷后延伸率下降，到一定階段后斷后伸長(zhǎng)率下降趨于緩慢。 </p> <p> (另外塑性大的抗拉強(qiáng)度和斷后伸長(zhǎng)率對(duì)拉伸速度的敏感性大，而塑性小的抗拉強(qiáng)度和斷后伸長(zhǎng)率對(duì)拉伸速度敏感性則相對(duì)較小。 </p> <p> <br /> </p> <p> 一般情況拉伸速度的變化對(duì)試驗(yàn)結(jié)果的影響如上，但對(duì)于塑料材料，它屬于粘彈性材料，它的應(yīng)力松弛過程與變形速度緊密相連。當(dāng)拉伸速度減小時(shí)，拉伸強(qiáng)度減小，斷裂伸長(zhǎng)率增大；拉伸速度增大時(shí)，塑料呈現(xiàn)脆性，拉伸強(qiáng)度增大，斷裂伸長(zhǎng)率減小簡(jiǎn)支梁沖擊試驗(yàn)機(jī)。
