拉力試驗(yàn)機(jī)主要由機(jī)型部分、測(cè)量部分、伺服驅(qū)動(dòng)部分、單片機(jī)測(cè)控系統(tǒng)、管理軟件等五方面組成。 </p> <p> <p> 1、機(jī)械部分：拉力試驗(yàn)機(jī)的機(jī)械部分包括立柱、機(jī)械平臺(tái)、減速齒輪箱、滾珠絲杠、固定橫梁、移動(dòng)橫梁等幾部分。在動(dòng)橫梁的滑道上有上下限位開(kāi)光裝置，能夠防止橫梁的突然上升或者下降將試樣的傳感器損壞。動(dòng)橫梁是由滾珠絲杠的旋轉(zhuǎn)來(lái)帶動(dòng)的，電機(jī)的主軸轉(zhuǎn)動(dòng)通過(guò)同步齒行膠帶轉(zhuǎn)移到減速器的滾珠絲杠上并帶動(dòng)橫梁上下移動(dòng)。 </p> <p> <br /> </p> 2、測(cè)量部分：拉力機(jī)的測(cè)量部分包括測(cè)力傳感器，光電編碼器、信號(hào)放大器、單片機(jī)、通訊電路、管理軟件等幾個(gè)部分。測(cè)量?jī)?nèi)容包括加載負(fù)荷測(cè)量、試樣變形測(cè)量、橫梁位移測(cè)量。加載負(fù)荷測(cè)量利用測(cè)力傳感器來(lái)測(cè)量，將力值的變化轉(zhuǎn)變?yōu)閼?yīng)變片電阻的變化，在通過(guò)電橋電路轉(zhuǎn)變?yōu)橄鄳?yīng)電壓的變化，通過(guò)對(duì)變化電壓的處理即可得出加載力的大小。橫梁位移的測(cè)量是通過(guò)伺服電機(jī)的增量式光電編碼器的反饋脈沖來(lái)獲得的，它的工作原理是通過(guò)對(duì)脈沖個(gè)數(shù)的計(jì)數(shù)來(lái)計(jì)算動(dòng)橫梁對(duì)應(yīng)的位移量，這些脈沖信號(hào)可以直接用單片機(jī)來(lái)計(jì)數(shù)和處理。 </p><p> 拉力測(cè)試機(jī)拉伸速度主要對(duì)于拉伸速度、斷后延伸率、屈服強(qiáng)度的影響。 </p> <p> <br /> </p> <p> 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(wàn)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(guò)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)。

伺服驅(qū)動(dòng)部分：拉力試驗(yàn)機(jī)的伺服驅(qū)動(dòng)部分包括伺服電機(jī)、驅(qū)動(dòng)驅(qū)動(dòng)器、單片機(jī)控制系統(tǒng)、通訊幾口、管理軟件機(jī)等幾個(gè)部分。伺服驅(qū)動(dòng)的功能是將計(jì)算機(jī)發(fā)出的命令通過(guò)單片機(jī)控制系統(tǒng)送給驅(qū)動(dòng)器，驅(qū)動(dòng)交流電機(jī)按設(shè)定的速度、方向轉(zhuǎn)動(dòng)，并適時(shí)停轉(zhuǎn)，從而控制動(dòng)橫梁的上升、下降、停止，完成試樣的拉伸和壓縮。 </p> <p> 單片機(jī)測(cè)控系統(tǒng)：拉力機(jī)的單片機(jī)測(cè)控系統(tǒng)是測(cè)量部分、伺服驅(qū)動(dòng)部分和管理軟件連接的中間橋梁，包括力值傳感器、變形傳感器、AD轉(zhuǎn)換器、光電編碼器等部分。通過(guò)傳感器將加載力的大小和試樣變形量的多少轉(zhuǎn)變?yōu)橄鄳?yīng)的電壓大小，經(jīng)過(guò)信號(hào)放大和AD轉(zhuǎn)換變成數(shù)字信號(hào)由單片機(jī)采集存儲(chǔ)，通過(guò)通訊電路送管理軟件計(jì)算，處理，繪制載荷—變形曲線圖。拉力試驗(yàn)機(jī)常見(jiàn)問(wèn)題以及解決方案。湖南定制型拉力試驗(yàn)機(jī)價(jià)格</p><p
