但試驗費用較高、耗時較長，試驗的可重復(fù)性和規(guī)律性較差，因此***采用人工模擬環(huán)境試驗，也就是采用環(huán)境試驗機，主要的環(huán)境試驗機有下列幾種：a.老化試驗機b.濕熱試驗機又分：恒定溫濕試驗機、交變濕熱試驗機、常溫濕熱試驗機c.溫度沖擊試驗機如：管材冷熱循環(huán)試驗機d.壓力沖擊試驗機如：管材壓力循環(huán)試驗機e.煙霧試驗機f.密封試驗機g.低氣壓試驗機h.霉菌試驗機i.防腐試驗機j.外力試驗機如全自動落錘沖擊試驗機、門窗力學(xué)性能試驗機、接插件拉力壓力試驗機k.高低溫試驗機二、對于力學(xué)性能試驗，可分為動態(tài)試驗機和靜態(tài)試驗機（1）動態(tài)試驗機：以一定的頻率按要求的波形對試樣進(jìn)行長期試驗，直至一定的時間或試樣破裂。如高頻疲勞試驗機、低周疲勞試驗機等。（2）靜態(tài)試驗機：以勻速的方式對試樣施力，直至試樣破斷。如***試驗機、壓力試驗機等。三、根據(jù)使用方式，還可分為在線檢測試驗機和非在線檢測檢測試驗機（1）在線檢測試驗機在生產(chǎn)設(shè)備聯(lián)用，在生產(chǎn)過程中就能知道產(chǎn)品的某些物理性能。如鋼管生產(chǎn)線中的管材耐壓爆破試驗機，**后一道生產(chǎn)流程就是向鋼管中充水做打壓試驗。（2）非在線檢測檢測試驗機大部分的試驗設(shè)備均在試驗室工作，都屬于非在線檢測檢測試驗機。疲勞試驗機也將更加的人性化、智能化和功能化4。</p><div

試驗機機種分類編輯試驗機分為化學(xué)成分試驗機和物理性能試驗機，他們之間都有不同的功用，都是用來檢測產(chǎn)品是否符合國家規(guī)定的相關(guān)標(biāo)準(zhǔn)。試驗機行業(yè)主要生產(chǎn)制造以下八類產(chǎn)品：金屬材料試驗機；沖擊試驗機：用來于測定金屬材料在動負(fù)荷下抵抗沖擊的性能，以便判斷材料在動負(fù)荷下的性質(zhì)。分為手動沖擊試驗機、半自動沖擊試驗機、數(shù)顯沖擊試驗機、微機控制沖擊試驗機等；沖擊試驗低溫儀：是金屬低溫沖擊試驗中**理想的試樣冷卻、保溫設(shè)備；沖擊試樣缺口拉床：加工試樣缺口，分為沖擊試樣缺口手動拉床、沖擊試樣缺口液壓拉床和沖擊試樣缺口電動拉床等沖擊試樣缺口投影儀，用來檢測加工出的試樣缺口是否合格；***試驗機：主要用于金屬、非金屬的拉伸、壓縮、彎曲和剪切試驗。試驗操作和數(shù)據(jù)處理符合國標(biāo)GB/T228-2010《金屬材料室溫拉伸試驗方法》的要求，如果改變結(jié)構(gòu)形式及更換相關(guān)零件，可同時滿足ASTM，ISO等國際相關(guān)標(biāo)準(zhǔn)的要求。適用于冶金、建筑、輕工、航空、航天、材料、大專院校、科研單位等領(lǐng)域。分為數(shù)顯式***試驗機、微機屏顯式液壓***試驗機、微機控制電液伺服***試驗機等2.非金屬材料試驗機；液壓***試驗機3.力與變形測試儀器。檢測設(shè)備一般有疲勞試驗機和游標(biāo)卡尺7。浙江飛機結(jié)構(gòu)件疲勞試驗機</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(biāo)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(dá)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(fù)，所以即時準(zhǔn)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(zhǔn)確的標(biāo)距測量和記錄裝置（如圖）。試樣標(biāo)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(zhǔn)確地測量試樣的應(yīng)變量，并即時地記錄下來。4.可以準(zhǔn)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(biāo)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(biāo)距。試驗完成后。浙江飛機結(jié)構(gòu)件疲勞試驗機</p><p
